Promising Practices in STEM Teaching and Learning: A Meta-Synthesis
The term STEM was first used in the 1990s and was frequently used to label anything that involved one or more
of the following four disciplines: science, technology, engineering, or mathematics (Bybee, 2010). Mathematics
and science have been the focus of practical applications of science, technology, engineering, and mathematics
(STEM), while technology and engineering have taken a back seat. Often technology teachers claim that they
integrate the T and E in STEM, but they continue to think of STEM as a set of four separate subjects (Sanders,
2009). Technology influences the lives of people every day in a myriad of ways, but the typical person
understands little about it. An increased emphasis of technology in education would position students to better
understand the changes in the world around them and how the use of technology is integral to science,
engineering, and mathematics applications (Bybee, 2010). Advocates of STEM education have encouraged
increased integration of technology and engineering in the K-12 curriculum. Technology is more than just
computer literacy; it includes handheld devices and instruments that can be applied in science and engineering.
STEM literacy includes and integrates literacy in all four subject areas. Scientific literacy can be defined in
terms of knowledge and processes applied to decisions in the natural world. Technological literacy involves not
only the ability to use new technologies but also an understanding of how they are developed and how they
affect our lives. Engineering literacy includes using the engineering design process to solve problems that cross
discipline lines. Mathematical literacy requires students to be able to analyze and reason in order to solve
problems and interpret solutions (Hanover Research, 2011). Interdisciplinary STEM education creates a synergy
expanding beyond the four individual subject areas toward the solving of problems that overlap the four
disciplines and their subcategories. Unfortunately, the integration of STEM education in the K-12 classrooms
has been slow. Many high schools claim to implement a STEM program, but the subjects continue to be taught
in isolation with few connections between them. Although these efforts may be a start in the right direction,
they need to move more definitively in the direction of Project-Based Learning (PBL) using the engineering
design process to solve problems that include other subject areas (Lantz, 2009). One event that may help to
move the education field toward integrated STEM is the inclusion of technology literacy on the National
Assessment of Educational Progress (NAEP). Requiring STEM education for all students will be a step toward
better preparation of students for the highly technological and quickly changing world today (Bybee, 2010;
Dugger, 2010).
Providing a high-quality education that prepares students for majors and careers in STEM fields remains
challenging for educators. Over the last 8-10 years, there has been an increased interest in exposing students to
integrated studies in STEM areas to better prepare them to solve 21th century problems that require knowledge
in multiple fields. New or modified teaching strategies that emulate real world work situations may be required
to successfully implement the new experiences in learning. The purpose of this study is to determine what
STEM strategies have been effective in increasing student knowledge and ultimately an interest in STEM fields.
Research Question
What are the promising practices in middle and high-school STEM teaching and learning?
Texas A&M University 5
Article Coding Procedures
To answer the research question, a comprehensive search of STEM practices in teaching middle school and
high school was conducted using the following search terms for the title: "STEM practice" OR teaching OR
learning OR education OR "high school" OR "middle school" OR research NOT cell NOT cells
The idea of integrated STEM was first prominently used in classrooms around the United States in 2005; as a
result, the criterion for the time period surveyed was set for January 1, 2005 through the date of the search,
August 28, 2013. We did not require the word “STEM” in the title because the term was not widely used in the
earlier years. We considered any article that included some integration of at least two of the STEM fields to be
STEM.
We used two comprehensive search engines available through the Texas A&M University Library System:
Google Scholar and EBSCO. The Google Scholar search returned 1,128 hits, and the EBSCO Academic Search
Complete (with medical journals eliminated) returned 7,621 hits. We screened studies to eliminate those related
to an agricultural or medical meaning of “STEM” (e.g., plant stems, stem cell research), elementary level,
undergraduate level, or graduate level STEM education, and studies dealing only with STEM careers. We also
checked references on each codable study to locate additional articles. Studies used in this meta-analysis
consisted of journal articles, paper and poster presentations, dissertations, reports, and book chapters. We
collected all studies available that appeared to relate to middle school or high school STEM education, resulting
in a compilation of 509 artifacts with 61 of these artifacts fulfilling the criteria to be included in this meta-
synthesis. In the search for integrated STEM, there were likely articles missing that used technology in
mathematics or science education because there were no doubt thousands of them. Although the word “STEM”
was not a required criterion, and artifacts that integrated any two of the STEM subjects were accepted, there
would be many articles that use technology in mathematics or science education that would not meet the search
criteria (e.g., science simulation, math program). Sixty-one artifacts were classified into five categories Reform
Based Teaching and Learning (see Table 1), Informal Education (see Table 2), Teacher Factors (see Table 3),
Technology (see Table 4), and School Factors (see Table 5) and commonalities within the five categories were
sought. The rest of the report will detail these five categories.
Category 1: Reform-Based Teaching and Learning
Educational reformers who are interested in improving teaching and learning encourage teachers to use
practices that are student-centered and constructivist in nature such as inquiry-, Project-, and problem-based
learning. These practices enable students to (1) feel excited about the world around them; (2) engage
knowledgeably in public discussion about issues of scientific and technological concern; and (3) increase their
economic productivity as a result of knowledge and skill acquisition (NRC, 1996). Furthermore, reform-based
teaching and learning practices have a history of producing positive outcomes (Anderson, 2002) such as
increases in cognitive achievement and skills (Shymansky, Kyle, & Alport, 1983), scientific literacy,
vocabulary knowledge, conceptual understanding, critical thinking, and positive attitudes (Haury, 1993). The
results of these practices, however, are mixed. Strobel and van Barneveld (2009) conducted a meta-synthesis of
extant meta-analyses comparing problem-based learning to traditional classroom instruction. They found that
problem-based learning promoted long-term retention of content knowledge, developed skills, and satisfied both
teachers and students, whereas traditional practices were more effective for short-term retention of knowledge
which was measured by standardized exams. When Kirschner, Sweller, and Clark (2006) analyzed extant
research related to reform-based practices such as inquiry, problem-based learning, and other constructivist
Texas A&M University 6
approaches, they found that less able learners had a decrease in content knowledge after the reform-based
practices were implemented but reported these same students enjoying the experiences.
Artifact coding. The meta-synthesis on reform-based teaching and learning practices resulted in 25 artifacts
from the years 2005-2013 (see Table 1). The practices were classified as inquiry, engineering-design, Project-
Based Learning (PBL), problem-based learning, Legacy Cycle, and hands-on activities. Students were exposed
to reform-based practices in a variety of settings at different grade levels, explored a variety of STEM-related
subjects, and were immersed in these STEM-related learning environments for different lengths of time. In
addition, different target groups of students were the focus of the studies and some teachers received
professional development (PD). Students were exposed to these reform-based strategies in both formal and
informal settings. Fourteen studies examining students in formal classrooms and the remaining 11 in informal
settings such as afterschool and weekend programs (3), summer programs (5), or combined afterschool and
summer programs (3). Students were in middle school (12), high school (11), or both (2). These students were
involved in different subjects related to integrated STEM, Science, Mathematics, Engineering, and Technology
along with writing, reading, and social studies. Students were engaged in STEM-related projects using six
different reform-based practices for one week or less (3), two to five weeks (6), six weeks to one semester (6),
or more than one year (6). Four of the studies did not describe the length of time that students were engaged.
Groups of females (10) and minorities (8) were targeted in the various studies. In nine of the 25 studies, the
students’ teachers received PD designed to aid them in the implementation of the reform-based practices. Most
of these reform-based teacher and learning practices focused on the following: 1) enhancing students’ content
knowledge (17), 2) developing students’ skills (8), 3) increasing students’ use of technology (3), 4) promoting
students’ interests in STEM-related college majors and careers (8), 5) examining students’ perceptions and
attitudes (12), and 6) providing rich learning environments for students (1).
Findings. In the meta-synthesis studies, inquiry was the most used reform-based teaching and learning practice.
Though it is a widely-used practice, inquiry has a myriad of meanings. These meanings change depending on
the context (e.g. Aulls & Shore, 2008; Grandy & Duschl, 2007; NRC, 1996). Inquiry was used in nine of the
meta-synthesis studies, and it was not defined in four of these studies (Duran, Hoft, Lawson, Madjahed, &
Orady, 2013; Heggen, Omokar, & Payton, 2012; Hylton, Otoupal-Hylton, Campbell, & Williams, 2012;
Wimpey, Wade, & Benson, 2011). Little and Leon de La Barra (2009) only briefly described inquiry as
questioning and hands-on minds-on. Ricks (2006) provided additional descriptions of inquiry as a student-
centered, active learning practice focusing on questioning, critical thinking, and problem-solving. Ricks (2006)
also stated that inquiry should mirror as closely as possible the enterprise of practicing real science. Three of the
studies described inquiry according to the National Science Education Standards’ definition of scientific inquiry
(Ketelhut, 2006; Kim et al., 2011; Williams, Ma, Prejean, Ford, & Lai, 2007). The National Science Education
Standards defines scientific inquiry as
…the diverse ways in which scientists study the natural world and propose explanations based on
the evidence derived from their work. Inquiry also refers to the activities of students in which they
develop knowledge and understanding of scientific ideas, as well as an understanding of how
scientists study the natural world. (National Research Council, 1996, p.23)
This definition captured both the role of inquiry in scientific endeavors and the activities of students as they
developed knowledge and understanding of scientific activities and how scientists study the natural world.
Engineering-design was used in five of the 23 research studies included in this meta-synthesis. The authors of
two studies stated that they had used an engineering-based practice; however, they failed to define what they
Texas A&M University 7
meant (Hudson, English, & Dawes, 2012; Klahr, Triona, & Williams, 2007). The authors of the remaining
studies defined engineering-design too differently but the core of the descriptions remained the same - the
identification and design of a solution to address the needs of the problem and the testing of the solution
(Mehalik, Doppelt, & Schuun, 2008; Schnittka, 2008; Richards, Hillock, & Schnittka, 2007). The engineering-
design practice was described concisely by Mehalik, Doppelt, and Schuun (2008) as a practice that systems
engineers used in the design and analysis of systems with iterative stages where students articulated their own
needs for a design. Students followed the following seven stages of a design process where they describe the
current situation, identify needs, develop criteria, generate alternatives, choose an alternative, create and test
prototypes, and reflect and evaluate.
Studies incorporating PBL were also found (4). While two of the four studies contained claims that students
engaged in PBL, they neither defined what they meant by PBL nor provided sufficient detail (Brown et al.,
2010; Kampe & Oppliger, 2011). The two studies that contained definitions both recognized PBL as a
constructivist practice where students had the opportunity to design their own projects and find solutions to
open-ended problems collaboratively (Lou, Liu, Shih, & Tseng, 2011; Olivarez, 2012). Olivarez (2012) also
discussed how PBL encourages student motivation and promotes academic rigors along with encouraging
multiple subject area integration and proper scaffolding by the instructor.
Reform-based practices that were not used as often as other practices, according to this meta-synthesis, included
problem-based learning, (3) and the Legacy Cycle (2) along with general hands-on (2) activities. Lou, Shih,
Diez, and Tsend (2011) defined PBL as a student-centered practice used in a meaningful learning situation that
was focused on the solution to a problem taken from a real situation. Students took initiative to construct
knowledge and effectively developed a solution to the problem by providing the resources, guidance, and
opportunities for exploration. Duran and Sendig (2012) described their study as design-based inquiry; however,
they did define what they meant and contextually their student intervention appeared to incorporate problem-
based learning. Zhe, Doverspike, Zhao, Lam, and Menzemer (2010) did not define problem-based learning.
Two other studies incorporated the Legacy Cycle. Klein and Sherwood (2005) defined the Legacy Cycle as a
practice where a strong contextually based challenge was issued to students and they had to generate ideas, view
different perspectives, research, complete formative self-assessment, and share their product, whereas Kanter
and Schreck (2007) discussed the benefits of the Legacy Cycle. These benefits included the student learning
concepts via inquiry in answering the driving questions and motivating students. The two studies using hands-
on practices did not provide enough detail to determine how specific reform-based practices were used
(Menzemer, 2007; Mosina, Belkharraz, & Chebanov, 2012). However, students in both studies engaged in their
own projects and explored, probed, observed, and collected data.
Reform-based learning practices were the focus of 25 studies explored in the meta-synthesis. Inquiry and
engineering-design were the most widely used practices; however, Project-Based, problem-based, Legacy
Cycle, and hands-on were also represented. Though we were able to classify these studies, with the exception of
hands-on, according to the practice used, many of the studies either did not define the practice used or rarely
provided definitions for the practice that closely matched the definitions found in other studies. Only three of
the studies (inquiry) contained the same definition for practice because of their use of the National Science
Education Standards. Though care was taken in categorizing these practices, the results are uncertain due to the
lack of uniformity or the dearth of definitions provided when the studies labeled the reform-based learning
strategy used.

Conclusions. Student outcomes from reform-based teaching and learning practices centered around six
subcategories: content, skills, technology use, majors and careers, perceptions and attitudes, and learning
environments.
Content Knowledge: One of the main goals of the reform-based teaching and learning strategies found in the
studies appeared to be increasing students’ content knowledge (17). For studies exploring the effects of inquiry,
four out of six showed positive gains pre- to posttest on students’ content knowledge regarding STEM, science,
technology, and math (Duran et al., 2013; Hylton et al., 2012; Ricks, 2006; Williams et al., 2007). Heggen et al.
(2012) found that students who participated in the inquiry-based afterschool program had higher science and
mathematics scores than their peers. Wimpey et al. (2011) had mixed results when they compared the pre- and
posttest gains between students in an inquiry setting versus students in a traditional setting. Inquiry students
showed greater posttest gains for Algebra than the traditional students; however, these students showed lower
gains for Algebra II than traditional students. The inquiry students’ science scores did show greater gains than
traditional students. Little and Leon del la Barra (2009) did not report any gains for their students’ engineering
and technology knowledge.
Engineering-design based practices appeared to offer benefits for students’ development of content knowledge.
Three of the four engineering design-based studies encompassing content knowledge also demonstrated
increases in students’ content knowledge in science, engineering, and math (Mehalik, Doppelt, & Schuun, 2008;
Schnittka, 2012; Richards, Hallock, & Schnittka, 2007). Furthermore, Mehalik et al. (2008) found that science
content knowledge increased more on the posttest for engineering design-based projects than inquiry. In
addition, the engineering design-based approach helped low achieving African Americans more than any other
group of students. Klahr et al. (2007), however, did not find any difference from pre- to posttests between
virtual engineering design-based learning environments and physical hands-on learning environments for
students’ engineering content knowledge.
Unlike the previous practices, the outcomes expressed in the PBL studies did not emphasize content knowledge.
Only one of the four PBL studies examined the results of the teaching and learning practice for content
knowledge. Lou, Liu, Shih, and Tseng (2011) found that there were significant positive differences between
students’ content and procedural knowledge in STEM when the students participated in PBL rather than
traditional practices. The focus of the other reform-based teaching and learning practices was increasing content
knowledge, with four of the six studies providing results. The results, however, were mixed with only Klien and
Sherwood (2005) and Menzemer (2007) reporting positive results. Klien and Sherwood found that students who
were taught using the Legacy Cycle to study an interdisciplinary biomedical engineering curriculum had
significantly greater gains in biology, physics, and anatomy and physiology content knowledge than students in
traditional classrooms. Menzemer (2007) reported that both typical students and Special Learning Disability
students showed gains in content knowledge related to STEM when engaged in hands-on activities. Studies by
Lou, Shih, Diez, and Tseng (2011) and Kanter and Schreck (2007) had mixed results for increasing content
knowledge. The qualitative results from Lou et al.’s study revealed that students had mixed thoughts on the
development of their STEM content knowledge. Some students reported that problem-based learning helped
them develop their content knowledge, whereas some students said that it did not. Students were, however, able
to connect and apply mathematics knowledge to their scientific knowledge. Kanter and Schreck, when
implementing the Legacy Cycle, found that students who had a greater initial understanding of biological
concepts scored higher on the more cognitively difficult concepts and application and were more likely to show
results of meaningful understanding. Students who demonstrated a low level of biological content knowledge
understandings were only able to show gains in basic biological understanding.

Skills: Another student outcome that researchers examined while exploring the effects of reform-based practices
was the development of skills related to STEM. Overall, the reform-based teaching and learning practices
increased students’ skills in various STEM related subjects. Studies examining Engineering-Design Based
practices did not explore students’ STEM-related skills. Skill development was studied in three of the eight
inquiry studies. Both Duran et al. (2013) and Little and Leon de la Barra (2009) found using pre- and posttests
that students’ technology skills increased while engaged in inquiry activities. Williams (2007) reported that
inquiry skills did not improve between pre- and posttests. They believed this was a result of students not
engaging in a systematic process, not being able to focus on a specific design, goal, or process, and that the
facilitators lacked the knowledge to guide their students through the inquiry process. PBL had a positive impact
on students’ writing, technology (Brown et al., 2010), and STEM-related workforce skills (Kampe & Oppliger,
2011). Olivarez found that when PBL practices were compared to traditional practices that students’ math,
science, and reading skills differed significantly with students having higher gains as a result of PBL (2012).
Problem-based learning practices had a positive impact on students’ skills development such as critical
thinking, inference, and inductive reasoning (Duran & Sendag, 2012). Students also used engineering skills to
guide their problem-solving skills (Lou, Shih, Diez, & Tseng, 2011).
Technology Use: The use of increased technology was another student outcome that was studied by researchers
examining the implementation of STEM reform-based practices. This increased use of technology was
supported by Heggen et al. (2012) who found that inquiry-based practices increased students’ use of both
mobile phones and computers. The increase in technology use included solving mathematical and scientific
problems. Duran et al. (2013) found that when students engaged in inquiry-based learning the results of their
technology use were mixed. Students increased their use of common technology during the intervention but
only half of the students increased their use of more advanced STEM technologies. Students’ use of basic
STEM tool sets stayed the same through the intervention. Students increased their use of technologies while
engaged in PBLs, such as software for databases, robotics programing, modeling, and computer game
development along with communicative technologies such as blogs, podcasting, and social networking (Kampe
& Oppliger, 2011).
Majors and Careers: A goal of many of the implementations of reform-based practices was to increase
students’ interests in STEM majors and future careers. As a result of being engaged in problem-based learning
practices revolving around STEM, females realized that they could have a career related to STEM due to their
knowledge development, activities they participated in, and interest towards STEM which was fostered during
the intervention. They also realized that they needed to promote their own abilities so they could have a career
in STEM (Lou, Shih, Diez, & Tseng, 2011). Problem-based learning programs also increased both male and
female students’ desire to participate in and confidence towards having a STEM-related career (Zhe et al.,
2010). For hands-on practices, 81% of underrepresented minority students who were involved in a youth center
promoting STEM chose to enter a STEM-related major. PBLs also had positive impacts on students’ desire to
enter STEM fields; Kampe and Oppliger (2011) found that 64% of their students had an interest in having a
STEM career. While other reform-based practices showed positive results related to STEM majors and careers,
inquiry-based practices had mixed results. After engaging in inquiry-based practices students were more
positive about having a science-related (Heggen et al., 2012; Ricks, 2006) or computing-related (Heggen et al.,
2012) career, did not demonstrate a change towards their desire to become an engineer (Little & Leon de la
Barra, 2009), and were mixed in their desire to pursue a STEM career (Duran et al., 2013). Students who had
previously thought about having mathematics as a career continued their desire to enter a mathematics field,
whereas students who were uncertain about mathematics as a career became less inclined to enter the field after
engaging in inquiry-based practices (Duran et al., 2013).
Texas A&M University 10
Perceptions and Attitudes: Many of the researchers examined student perceptions and attitudes towards STEM
related-activities, interests, attitudes towards STEM in general or a specific STEM subject, attitudes towards
people involved in STEM careers, and their self-efficacy regarding their abilities to be successful towards
STEM content and skills. Overall, students who engaged in inquiry-based practices had positive attitudes and
perceptions towards STEM. These students had developed increasingly positive attitudes towards learning
science (Ricks, 2006) and computing (Heggen et al., 2012) and strengthened their confidence in mathematics
and science skills (Hylton et al., 2012). Furthermore, if attitudes towards science or STEM were overwhelming
positive, these attitudes did not change during the intervention (Duran et al., 2013; Heggen et al., 2012). One of
the studies found that students with higher self-efficacy initially collected more data using their scientific
inquiry skills in a virtual environment; however, after several visits self-efficacy no longer had an impact since
both low and high self-efficacy groups were collecting data equally. Also, self-efficacy did not have an impact
on the gathering of different sources within the virtual environment (Ketelhut, 2006). Another study found that
though the attitudes towards science and scientists were positive for males after the intervention, females were
just anxious towards science though their views towards science became more positive. The females also
reported that technology made science learning interesting, made the data more accurate, and helped with
visualization and understanding (Kim et al., 2011). Studies using engineering design-based practices showed
mixed results. In classrooms where engineering design and science content were integrated, attitudes towards
engineering were more positive as a result of the interventions with female students showing greater gains
(Schnittka, 2012). However, in a physical science and engineering environment using either hands-on or virtual
activities, the confidence level towards the ability to use engineering was the same for students participating in
the activities, but the female students’ confidence was consistently lower than males (Klahr et al., 2007). PBL
practices also showed mixed results. Students had positive attitudes towards their summer workshop experience
(Kampe & Oppliger, 2011) and STEM PBL practices had a positive influence on students’ behavioral
intentions, attitudes, and desire to learn (Lou, Liu, Shih, & Tseng, 2011). However, PBL did not have an impact
on students’ self-efficacy and caused it to decrease towards social studies (Brown et al., 2010). When hands-on
practices were used, both typical and Special Learning Disability students were satisfied with their STEM
intervention, were more interested in STEM, and had higher self-efficacy towards STEM. The Special Learning
Disability students, however, showed lower results on perceptions and attitudes towards STEM, but nonetheless
these results were still positive.
Learning Environments. Reform-based teaching and learning practices can promote students’ STEM learning in
an interactive and technology-based environment. Hudson et al. (2012) examined female students in an
engineering design-based learning environment. They found that their students exhibited the following
behaviors: 1) sought opportunities to clarify engineering terms that enabled them to enter into discourse around
their design and construction of an engineering prototype, 2) connected the task to their conceptual
understandings, 3) asked questions that advanced their project design and construction, and 4) discussed the
practicalities of their design and debated ideas without being judged. As a result of the type of learning
environment that enabled the female students to engage in those types of activities, the students were successful
in the engineering design-based project and had positive STEM-interactions.

Category 2: Informal STEM
Informal STEM learning environments generally provide occasions for scientific learning minus the time
constraints generally found in more formal settings (Hofstein & Rosenfeld, 1996). Informal learning settings
(i.e., museums, zoos, science centers, and science camps) often have the tools, resources, and expertise to
support STEM learning opportunities. The advantages of flexible time constraints in informal learning
environments facilitate greater chances to augment conceptual learning, reflection time, assessment of subject
matter, and informal discussions. These environments provide opportunities to facilitate student understanding
and transform science processes and concepts. Within informal science settings there are many opportunities for
scaffolding student science knowledge, attitudes, and science and STEM career options.
The TIMSS report suggested that because the United States places considerable emphasis on STEM instruction
and learning in formal settings (schools), they may overlook opportunities for rich informal science education
resources for reinforcement (Lee, 1998). Gerber, Cavallo, and Marek (2001) found that a large percentage of
students’ science learning can happen in informal learning environments outside formal classroom walls in
places like homes, camps, museums, after school programs, or in everyday experiences (Gerber et al., 2001).
When students engage in valuable informal STEM activities, they possess higher scientific reasoning abilities
than those who are not participating (Gerber et al., 2001).
National education groups have examined the impact of informal science on STEM knowledge. The National
Research Council (NRC, 1996) suggested that informal science education can complement and scaffold STEM
teaching and student learning. The implementation of programs intended to increase K-12 student involvement
in STEM, both formal and informal, was a priority for the mitigation of the shortage of students going into
STEM careers and measuring the effectiveness of these programs was necessary to be ensured of the programs’
impact (National Science Board [NSB], 2010). The NSB (2010) demonstrated the demand for equality across
students (race, gender, ethnicity) within STEM programs. The National Academy of Sciences (NAS
Committee, 2007) advocated for increasing participation in STEM of underrepresented minority and low-
income students. This participation may lead to further success of the STEM initiative. The NAS stated that
summer inquiry-based research programs were one venue for increasing participation of underrepresented
minority and low-income students.
Informal science learning has gained prominence as a possible contributor to student learning. These informal
environments also can be viewed as mechanisms for linking formal and informal science education efforts to
produce further collaborative endeavors focused on improving student learning in the STEM areas (Falk,
Osborne, Dierking, Dawson, Wenger, & Wong, 2012; NRC, 1996). Research has shown us that students and
adults pursue STEM understandings in and out of school using community resources (Bell, Lewenstein, Shouse,
& Feder, 2009).
Artifact Coding. The meta-synthesis on informal education resulted in 22 artifacts from the years 2006 through
2012 (see Table 2). The venues for the studies which were classified as informal learning ranged from mainly
after-school programs/clubs (8) to summer camps (14) with some including follow-up mentorships. The lengths
of the activities ranged from 3 hours (1), 40 hours (2), 80 hours (1), two days (1), three days (1), four days (1),
one week (1), two weeks (5), one month (2), seven weeks (1), ten weeks (2),18 months (1) to a longitudinal
three-year (1) study. A total of 1,835 participants were studied within 20 of the studies that provided
Texas A&M University 12
demographics with a range from 21 to 239 participants within each study. Some of these participants were from
underserved, underrepresented, low SES, and minority populations (6 studies/576 students); some were chosen
randomly or by lottery (3 study/390 students); while others only attended if they had a high aptitude, high
STEM interest and/or high scores in mathematics and science (6 studies/ 420 students). Many informal
activities had more than one focus with one using as many as seven different teaching pedagogies. These
pedagogies included the following: inquiry, hands-on activities, PBL, technologies, small and large group
activities, field trips, modules, roles models, discussions, collaboration, science projects, and mentors. Most of
these informal activities contained a combination of two or more of these pedagogical strategies. Subject areas
included science, mathematics, engineering, technology, STEM, music, and robotics with some containing more
than one of these specific subject areas in the informal settings. Most of these informal activities focused on
specific objectives: 1) increasing student knowledge and understanding, 2) increasing the STEM pipeline by
developing a wider breadth of understanding for STEM careers, and 3) improving student attitude and
confidence in STEM areas.
Findings. Results indicated that informal venues enhanced content knowledge and understanding, career and
major choices, and attitudes and confidence.
Content knowledge: Williams et al. (2007) showed that students’ physics content knowledge increased during a
robotics summer camp with middle school students. The majority of secondary students after being exposed to
science careers in a 4-day summer STEM camp increased on measures of science content, motivation,
knowledge, and development of science (Marle, Decker, Kuehler, & Khaliqi, 2012). Ricks (2006) demonstrated
statistically significant gains in participants’ science knowledge after a month-long camp including fieldtrips
and hands-on activities. Johnson, Hayden, Farmer, Hataway, Reynolds, and McConner (2013) using a summer
research program approach with talented underserved students found that 97% of them enriched their learning
in STEM.
Careers and majors: Camp students were more likely to enroll in STEM classes and choose STEM majors,
increasing the STEM pipeline. Hubelbank, Demetry, Nicholson, Blaisdell, Quinn, Rosenthal, and Sontgerath,
(2007) demonstrated that middle school girls in their camp chose a greater number of elective mathematics and
science courses in high school and more of these girls later chose engineering as a major. In one camp with
challenging engineering tasks, 67% of the students improved their GPA and 98% went to college (Hylton et al.,
2012). In an after school and summer camp (Mosina, Belkharraz, & Chebanov, 2012), as many as the 81.8% of
campers chose STEM majors while 95% of the talented secondary students in another 2-week camp (Johnson et
al., 2013) thought about majoring in STEM. Camp students in a ten-week informal environment were also more
motivated to consider a career in STEM (Zhe et al., 2010). Retrospectively, Ricks (2006) discovered that a
significant number of high-STEM interested previous camp participants selected STEM majors. In general,
after school and summer camps focusing on STEM topics had a positive effect on students’ impressions of
STEM careers and were highly associated with students wanting to pursue a STEM career. What is not clear is
how many students already possessed a predilection for STEM, and this might have been manifested in their
choosing to attend an after school or summer STEM camp.
Attitudes and confidence: As a result of informal STEM interventions students’ experiences improved their
attitudes about STEM and self-confidence within respective STEM disciplines. Instructors noted an
improvement in middle school students’ self-confidence during their one month camp (Hylton et al., 2012). A
significant increase in positive student attitude toward and knowledge about engineering careers was found by
Hirsch, Kimmel, Rockland, and Bloom (2006) during their engineering focused camp. Likewise, Zhe et al.
(2010) noted that high school students in their camp increased their self-confidence in STEM and improved
Texas A&M University 13
their independent research skills. Ricks (2006) saw an improvement in science attitudes after a 4-week summer
camp. Hispanic campers had higher gains in their increased confidence of success in and intentions toward
science careers as they developed a science social niche and greater motivation and attitudes toward science
(Marle et al., 2012). Hoyles, Reiss, and Tough, (2011) demonstrated that there should be a STEM club in every
school because they promoted positive impacts for students.
Some studies found both positive and negative effects. In one intervention, there was a drop in scores after one
semester because camp students faced their misconceptions about the topic, but after more instruction and
reflection on the misconception, there was increased scientific understanding (Miller, Ward, Sienkiewicz, &
Antonucci, 2011). There were no significant differences in engineering self-efficacy (Hubelbank et al., 2007);
however, qualitative data showed no gender differences in self-efficacy or knowledge gains – even though
certain sessions in the camp appealed to specific genders and their effect and knowledge gained were not
compromised (Marle et al., 2012).
Conclusions. Findings from these informal activities indicated that camps and after school clubs and activities
produce positive results. Most of these informal activities improved content knowledge about STEM subjects,
students’ attitudes toward STEM, and choice of STEM majors. Some recommendations included having STEM
clubs in every school. It was also suggested that girls preferred workshops with social aspects. Thus, it is
important to provide more activities to engage girls. Many of the studies suggested a support system should be
included for students and parents using mentors and/or role models if at all possible. The studies on informal
education show some encouraging results when the use of these role models and mentors were included in their
camps and semester long research projects.
Category 3: Teacher Factors
Teacher factors are attitudes, knowledge, beliefs, and practices of the teacher that impact student learning and
instructional practices. Many factors contribute to a student’s academic success, but research has suggested
that, among school-related factors, teacher factors matter most (Rand Corporation, 2012). Teacher factors
included, for example, teachers’ willingness to integrate technology (Yoon, 2010), or teachers’ perceptions of
the “type” of student that they would encourage to pursue engineering studies (Nathan, Tran, Atwood, Prevost,
& Phelps, 2010). Teacher factors also included classroom factors that were determined by the attitudes, beliefs,
or practices of the teacher, for example fostering students’ team skills through teacher designed collaborative
learning activities. Some overlap of the artifacts may be present among the categories—such as technology.
Artifacts for the meta-synthesis were categorized as teacher factors if the artifact, in some way, addressed
student outcomes related to teacher factors.
Artifact Coding. Twelve artifacts were retained from the literature search that pertained to the influence of
teacher factors on student success in STEM secondary education (see Table 3). Themes related to teacher
factors were identified through an iterative process of constant comparison among the 12 artifacts. Early in the
analysis process, tentative linkages were developed between theoretical themes and evidence of effectiveness as
demonstrated in student outcomes. As the coding progressed and themes for effective teacher factors for STEM
teaching and learning were categorized, the coding process shifted towards verification. Artifacts were revisited
and reviewed again as additional themes and evidence of teacher factors emerged.
Findings. Six principle themes for teacher factors were identified within the 12 artifacts analyzed: a) high
teacher content knowledge, b) deep understanding of STEM teaching practices (effective pedagogy), c) frequent
and effective integration of technology, d) effective use of team skills and collaborative learning, e) high teacher
Texas A&M University 14
self-efficacy, and f) emphasis on “deliberate instructional practice.” Evidence among the artifacts indicates
positive student outcomes (e.g., improved content knowledge, improved skills, or improved attitudes towards
science) for the six teacher factors. Each of the six themes is discussed in more detail in the following sections.
Teacher content knowledge: Teacher content knowledge had a substantial impact on student outcomes. Five of
the artifacts reviewed established a positive relationship between teachers’ content knowledge and students’
gains in content knowledge (Moskal, Skokan, Kosbar, Dean, Westland, Barker, & Nguyen, 2007; Silverstein,
Dubner, Miller, Glied, & Loike, 2009; Ragusa, 2012; Lambert, 2007; Hotaling et al., 2012). The higher the
teachers’ knowledge of the subject matter, the higher the students’ performance, after instruction, on concept-
inventory type tests. Instruments used to measure content knowledge included state standardized tests,
researcher developed content-specific tests, and passing rates on state mandated science or mathematics tests. In
four of the five cases exploring the influence of teacher content knowledge, the research on student outcomes
followed a teacher PD series that included a component of instruction dedicated to building content knowledge
in specific areas of current research and technology. All four PD series, however, also included in-depth
instruction of STEM teaching strategies (for example problem-based learning, inquiry, or engineering design).
In most cases, it was not possible to separate the effects of increased teacher content knowledge on student
outcomes from improved teaching strategies or other teacher factors. Clear evidence of this relationship,
however, was demonstrated in one study by Hotaling et al. (2012). Researchers grouped the teacher
participants by posttest content scores into three categories: low content knowledge, medium content
knowledge, and high content knowledge. They then compared student scores, following an instructional
intervention, by teacher category. High posttest teacher scores significantly predicted higher posttest student
scores, especially for the weaker students. In contrast, both weaker and stronger students had lower posttest
scores if their teachers’ scores were low, but the weaker students did very poorly when this was the case.
Teachers may take several years to translate new content knowledge into educational practices. Silverstein et
al. (2009) found that it took three to four years, following a PD experience focused on authentic research
experience, to see an increase in the teachers’ students’ scores on the state assessment for science. In years three
and four following the research experience for teachers, students of the participating teachers scored
significantly higher (10.1 percent) on the state assessment for science than students of non-participating
teachers. Integrated teacher content knowledge positively affected student learning. Teachers with a broad
content base tended to teach with a greater degree of science discipline integration, and the students of these
teachers outperformed students of teachers who taught with a discipline specific focus (Lambert, 2007).
Based on evidence from the artifacts reviewed, teacher content knowledge appeared to be the most critical
teacher factor contributing to student success in STEM secondary education. Teacher content knowledge was
most effective when it was broad, covered a range of disciplines, and integrated. STEM teachers should have
an understanding of concepts in mathematics, physical sciences, life sciences, and geoscience. And, once
teachers acquired new content knowledge, it took additional time to translate the content knowledge to
educational practices.
STEM teaching practices: Teachers’ understanding and effective use of STEM teaching practices had a positive
impact on student outcomes. A deep understanding of STEM teaching practices was explored by five of the 12
artifacts reviewed (Moskal et al., 2007; Silverstein et al., 2009; Mji, 2006; Finson, 2006; Ragusa, 2012).
Teacher instructional practices that modeled authentic scientific and engineering practices fostered improved
student content knowledge, increased skills, and improved attitudes towards STEM disciplines and careers.
These instructional practices included integration of content and problem-solving tasks (Moskal et al., 2007);
use of constructivist education practices (Silverstein et al., 2009); data-driven instruction (Silverstein et al.,
Texas A&M University 15
2009); and engineering inquiry-based learning (Ragusa, 2012). As an example, Silverstein et al. (2009)
described a PD activity in which teacher participants acted as researchers in a faculty mentor’s lab for 16 weeks
divided between two summers. Specific elements of the research experience, that Silverstein et al. (2009)
contributed to improved STEM teaching strategies, were the teachers’ lab management skills and confidence
gained from the research experience (self-efficacy), and the connections teachers made between studying an
authentic contemporary science problem and classroom applications of that problem. Teachers who were more
competent and confident in lab experiences and lab management skills were more likely to implement regular
demonstrations and experiments for their students. Students with regular exposure to experiments were then, in
turn, more likely to perform at a high level on the science portion of the National Assessment of Educational
Progress (NAEP) (Wenglinsky, 2000; Braun et al., 2009).
Unlike specific teaching strategies for STEM education, general teaching styles did not appear to have much
effect on students’ perceptions of science or scientists. Finson, Pedersen, and Thomas (2006) explored the
influence of teaching styles (didactic, conceptual, or exploratory) on students’ perceptions of scientists using
students’ drawings. It was hypothesized that students of the exploratory teaching style would have a broad
perception of scientists, whereas students of the didactic teaching style would have a stereotypical perception.
No correlation could be made between general teaching style and students’ perceptions of scientists. These
results, in combination with the other study results, inferred that specific teaching strategies, rather than
teaching styles, influenced student outcomes in STEM education. STEM teaching strategies should model
authentic scientific and engineering practices.
Integration of technology: The teacher’s ability to effectively integrate student use of technology is often
thought to have a positive impact on student outcomes in STEM education. Several artifacts mentioned teacher
use of technology during PD activities, but only three of the 12 artifacts analyzed for teacher factors directly
addressed the effects of teachers’ abilities and/or confidence for technology integration in the classroom on
student outcomes (Yoon & Liu, 2010; Hoyles et al., 2011; Hotaling et al., 2012). Hotaling et al. (2012) found
that teachers who were successful in utilizing technology (sensors) for the classroom had spent significant time
using the technology during a summer training period, had sufficient follow-up during the academic year with
support from the university, and had a high level of engagement with the learning community established
during the summer PD activity.
Yoon and Liu (2010) found a similar, but opposite trend. Teachers participating in a summer PD activity
demonstrated poor adoption of the technology used in their PD (simulation and visualization tools) due to lack
of time, lack of institutional support, and low engagement with a learning community. Yoon and Liu (2010)
made two critical distinctions in the study. First, communication technology differed from education
technology. Education technology was similar to “data-driven instruction” (Silverstein et al., 2009) where the
students were acting as scientists using technology as a tool to collect, organize, and interpret information.
Adoption and integration of education technology appeared to be more difficult. This may be due to the
simultaneous cognitive demands of teaching a new technology while also teaching skills for data analysis and
interpretation. Second, Yoon and Liu (2010) emphasized the importance of “negotiating the middle ground”
among the teacher, the institution (e.g., their school and district), and the students. Too often, contextual factors
were not considered when designing PD related to technology integration for secondary STEM education.
Among the artifacts analyzed for the meta-synthesis, integration of technology appeared to have a mixed effect.
Positive outcomes, due to technology, appeared to co-vary with other factors such as teacher content
knowledge, the presence of campus support, or active engagement within a learning community. Use of
education technology that encouraged data-driven instruction appeared to be the preferred method used in the
Texas A&M University 16
described PD activities. This may be because data-driven instruction reflects authentic science and engineering
practices.
Team skills and collaborative learning: Collaborative learning is a social process of knowledge building that
requires students to work as an interdependent team towards a clear objective resulting in a well-defined final
product, consensus, or decision (Wright et al., 2013). Collaboration requires team skills, and collaborative
learning requires structure and guidance from the teacher as the facilitator. Five artifacts out of the 12 artifacts
reviewed discussed teacher factors necessary to facilitate collaboration: such as grouping structure, grouping
process, or activity design (Duran et al., 2013; Moskal et al., 2007; Nag, Katz, & Saenz-Otero, 2013;
Nourbakhsh et al., 2005; Zhe et al., 2010).
Moskal et al. (2007) intentionally focused on collaboration during a PD event for teachers. Mathematics and
science teachers, who collaborated during the PD event to understand a STEM problem or to create a STEM
integrated lesson, were observed frequently utilizing collaborative learning and STEM integration in their
classroom by external evaluators. Students of the participating teachers were more likely than students in a
comparison group to indicate an interest in pursuing a STEM-related degree or career and demonstrated slightly
better scores on the state assessment test (Moskal et al., 2007). The effects of team skills and collaborative
learning cannot be isolated in this example from the effects of gains in teacher content knowledge or
pedagogical skills. Teachers, however, often teach the way they were taught. Collaborative learning in the PD
event increased the likelihood of the teacher fostering a collaborative learning environment in their classroom.
Poorly structured group activities may foster competition and isolation rather than team skills and collaboration.
Nag et al. (2013) explored a structured series of gaming competitions among students working remotely from
diverse locations across the United States. In order to incentivize collaboration, they used a model of “layered
collaboration.” Students worked together as a team, worked outside of their team in alliances, and worked with
opponents during competitions to achieve game objectives. The game was structured in an effort to encourage
collaboration within competition. Results of the tournament scores indicated alliances of teams scored higher on
average by more than one standard deviation than individual teams. In addition, the majority of game
participants agreed, through survey responses, that the competition had improved their leadership and team
skills, and had increased their interest in leadership. These results indicated the greater the degree of
collaboration, the greater the gains in student content knowledge and skills, in this case computer programming,
engineering-based problem solving, and leadership skills. Collaborative learning, a factor determined by a
teachers’ own learning experiences and skills for developing activities that encouraged students’ team skills,
supported positive student outcomes for STEM education.
Teacher self-efficacy: is a person’s belief in his or her ability to succeed in a particular situation. The most
effective way of developing self-efficacy, in a specific area, is through mastery experiences (Bandura, 1994).
The most effective way of developing self-efficacy for teaching STEM is to apply STEM content knowledge in
the context of real-world problem solving through authentic STEM research experiences (Silverstein et al.,
2009). Four of the 12 articles reviewed for teacher factors included evidence of a positive relationship between
teacher efficacy and improved STEM teaching and learning (Hoyles et al., 2011; Ragusa, 2012; Silverstein et
al., 2009; Yoon & Liu, 2010).
Silverstein et al. (2009) found that, following two summers of research experiences for teachers, the teachers’
use of constructivist education practices increased, their confidence to acknowledge their own gaps in content or
skills increased, and their skills in lab management skills increased. The authors attributed gains in teacher self-
efficacy for teaching STEM to the authentic contemporary research experiences and to the regard by the
Texas A&M University 17
scientists of the teachers as researchers (i.e., increased sense of professionalism). This increase in teacher self-
efficacy eventually translated to increased science scores for the students of the teacher participants. Similar to
other studies, however, it was not possible to attribute the positive student outcomes solely to teacher self-
efficacy. Rather, it inferred a combination of teacher content knowledge, pedagogical skills, and self-efficacy.
Deliberate instructional practice: is the intentional use of a set of activities designed to improve student
performance, challenge the learner, and provide feedback to the learner and the teacher through formative
assessment techniques (Marzano, 2011). Expertise is acquired by extensive engagement in practice activities
that are related to the broader learning goal, and individual differences in performance can often be attributed to
differences in the amount of deliberate practice (Ericsson, Krampe, & Tesch-Romer, 1993). Deliberate
instructional activities are designed by the teacher to help students improve specific aspects of their overall
performance. The deliberate practice is typically scheduled for a fixed period of time, on a regular schedule, and
of a limited duration. The activities must be appropriate, yet challenging, and the level of difficulty should allow
for successive refinement of skills through repetition, reiteration, and informative feedback (van Gog, Ericsson,
Rikers, & Paas, 2005).
Two of the artifacts reviewed for teacher factors contributing to success in STEM made an explicit association
between deliberate instructional practices and positive student outcomes. The deliberate instructional practices
investigated included the following: a) an emphasis on learning to read content-area text (Ragusa, 2012), and b)
teachers’ modeling of reflection (Hotaling et al., 2012).
An emphasis on learning to read content-area text, also referred to as disciplinary literacy (Shanahan &
Shanahan, 2008), was used to improve teacher performance and student learning in a quasi-experimental study
by Ragusa (2012). Disciplinary literacy, in contrast to content area literacy, is advanced literacy instruction
embedded within content-area classes. The difference is that content literacy emphasizes general reading and
communication techniques that a novice might use to make sense of text, while disciplinary literacy emphasizes
the unique strategies used by experts to read, understand, and communicate within a specific discipline.
Although Ragusa (2012) did not mention the term disciplinary literacy, the reading strategies taught were
utilized specifically for understanding and communicating STEM-disciplinary text and could be considered
instruction in disciplinary literacy.
In order to instruct students on the practices needed to understand the structure and use of scientific
informational text, teachers were taught, through a PD program, how to utilize question generation strategies
(QGS) and question answer relationship strategies (QAR) (Raphael & Au, 2005) specific to STEM-disciplinary
text (Ragusa, 2012). The teachers (n=53) then integrated these deliberate practices in their classroom instruction
with their students (~ 5,000). The result was higher student science knowledge, improved student science
literacy, and increased enthusiasm for science. Other factors, individually or synergistically, may have
contributed to these outcomes. In addition to deliberate practice on learning to read STEM-specific text, the PD
also incorporated teacher content knowledge and STEM pedagogical practices (specifically inquiry instruction).
A second deliberate instructional practice exhibiting significant positive student outcomes was that of teachers
modeling reflection. Reflection has been defined as a mode of understanding that requires “becoming critically
aware of one’s own tacit assumptions and expectations, and those of others, and assessing their relevance for
making an interpretation” (Mezirow, 2000).
Hotaling et al. (2012) described a cohort of teachers that was encouraged to model reflection by discussing
pretest results for algebra and electricity units with their students. The pretest results for each unit were put
Texas A&M University 18
online and were immediately available to be shared, aggregated by class, with the students. The results were
displayed in a graphical format. About half of the teachers participating in the study reported that they discussed
the pretest results with their students. Following the units of study, students’ posttest results (for content
knowledge) were compared by teachers that discussed the pretest results versus those that did not and by
weaker versus stronger students. Discussing the results was “correlated with significantly higher scores for both
stronger and weaker students. Even more important, it had the greatest impact on the weaker students, in some
cases almost equalizing the scores between the two groups” (Hotaling et al., 2012, p. 29). The authors did not
refer to the strategy of discussing pretest results as “modeling reflective thinking.” However, through discussion
of pretest results teachers were encouraging students to become aware of assumptions and expectations and to
self-assess their existing knowledge of the content—this was reflection.
Specific strategies or methods the teachers used to discuss the pretest results were not described. A better
understanding of how they facilitated reflection through discussion of the pretest results would have been
beneficial. Deliberate practice with disciplinary literacy, utilizing QGS and QAR strategies in order to model
and facilitate student reflection, could feasibly yield significant positive outcomes for STEM learning.
Conclusions. Six principle themes for teacher factors were discussed in this section: a) high teacher content
knowledge, b) deep understanding of STEM teaching practices (effective pedagogy), c) frequent and effective
integration of technology, d) effective use of team skills and collaborative learning, e) high teacher self-
efficacy, and f) emphasis on “deliberate instructional practice.” The central point condensed from review of the
12 artifacts related to teacher factors is that teacher content knowledge appears to be the most important teacher
factor impacting student outcomes. Other essential points related to teacher content knowledge include the
following: a) teacher content knowledge is a significant predictor for student academic success, b) gains in
teacher content knowledge are typically facilitated through summer PD activities, c) many of the PD programs
span a long period of time (up to two years) and include support for the teachers during the academic year, and
d) it takes a long time (two plus years) for teachers to transfer new content knowledge into actions and practices
in the classroom.
Effective STEM pedagogy appears to be the second most important teacher factor impacting student outcomes.
Teacher content knowledge and effective STEM pedagogy were often taught through the same PD program,
and positive student outcomes were attributed to both. Therefore, it is not feasible to state the impact of
improved STEM pedagogical practices separate from the influence of increased teacher content knowledge.
Effective STEM instructional practices included integration of content and problem-solving tasks (Moskal et
al., 2007); use of constructivist education practices (Silverstein et al., 2009); data-driven instruction (Silverstein
et al., 2009); and engineering inquiry-based learning (Ragusa 2012). Results indicate these instructional
practices foster improved student content knowledge, increased skills, and improved attitudes towards STEM
disciplines and careers.
Technology adoption and integration by the teacher appears to have a mixed effect on student outcomes.
Positive outcomes, contributed to technology, appear to co-vary with other factors such as teacher content
knowledge, the presence of campus support, or active engagement within a learning community. Use of
education technology that encourages data-driven instruction is the preferred method used in the described PD
activities. This may be because data-driven instruction reflects authentic science and engineering practices.
However, this is also the type of technology that has a low adoption rate among teachers due to factors such as
lack of time, lack of institutional support, and low engagement with a learning community. Positive student
outcomes as a result of teacher integration of educational technology depend more on the content knowledge,
self-efficacy, and STEM instructional methods of the teacher than they do on the technology itself.
Texas A&M University 19
Team skills and collaborative learning were discussed in five of the 12 artifacts reviewed for teacher factors. Of
these five, three made casual references to the importance of collaboration and how they structured
collaborative teams within the outreach and/or PD programs, but they did not measure student outcomes based
on levels or degree of collaboration. One artifact, however, described in detail how they structured teams,
activities, and criteria for the primary purpose of fostering multiple layers of collaboration while discouraging
passive cooperation and negative competition (Nag et al., 2013). They categorized the participants based on the
layer of collaboration they had achieved (up to 3 layers) and compared the score results among the categories.
They found that the greater the degree (or layer) of collaboration, the greater the gains in student content
knowledge and skills. Collaborative learning is a teacher factor that can enhance STEM student outcomes.
One artifact attributed gains in teachers’ self-efficacy to positive student outcomes (Silverstein et al., 2009).
However, others inferred the influence of teacher confidence for content, teacher confidence for a specific
technology, or teacher confidence for managing a lab/classroom to positive student outcomes. Although teacher
self-efficacy appears to be an important teacher factor for STEM success, the artifacts reviewed inferred that it
was strongly associated with teacher content knowledge and STEM instructional practices.
Deliberate instructional activities were designed by the teacher to help students improve specific aspects of their
overall performance. Deliberate teacher practices discussed by two of the artifacts reviewed for teacher factors
were an emphasis on learning to read content-area text and teacher modeling of reflection. Both artifacts
presented results from quasi-experimental research indicating significant positive student outcomes associated
with these practices.
Teacher factors are a significant contributor to student academic success in STEM. Teacher content knowledge
is the most crucial of the teacher factors, followed by STEM instructional practices (or pedagogy). Integration
of technology, teacher self-efficacy, and team-building skills are closely associated with teacher content
knowledge and STEM instructional practices. PD programs, therefore, should concentrate on building STEM
content knowledge in an authentic context (e.g., research) paired with instruction/modeling on how to modify
the content and research practices into STEM instructional practices. PD that prioritizes building teacher
content knowledge should include multiple sessions over an extended period of time with support provided
during the academic year. Lastly, program directors and stakeholders should not expect an immediate direct
impact on student learning resulting from increased teacher content knowledge. It takes considerable time to
transfer new content and skills into classroom practices.
Category 4: Technology
Artifact Coding. There were 25 articles, presentations, posters, or other documents that discussed integrating
technology with mathematics, science, or engineering, resulting from the search for STEM teaching and
learning artifacts from 2005 through 2013 (see Table 4). There are doubtless many more articles that describe
the use of technology in teaching mathematics, science, or engineering, but they did not meet the search criteria
and thus were not included. For example, the search terms would not have identified an article about
simulations in science or animations in mathematics. There are many technology-related terms that were not
included in the search; the main focus was on STEM integration. Determining the categorization of the studies
and activities that used technology was problematic because technology can cut across all types of educational
settings (formal and informal), was used in different teaching strategies (e.g., problem-based learning, PBL,
inquiry, engineering design), was used for different purposes (e.g., increase content knowledge, improve
Texas A&M University 20
attitudes towards STEM), and there were many different types. There were no other particular themes that
emerged common among studies using technology other than the integration of STEM-related subjects. The
decision was made to discuss these artifacts by type of technology used though many used a combination of
different types of technology.
Robotics. More than half (13 of 25) of the artifacts that discussed the use of technology as part of STEM
integration described robotics projects. Three of the studies addressed content knowledge, eight focused on
technology skills, nine discussed STEM interest, and nine others concentrated on 21st century skills. All of the
robotics projects were implemented in informal environments, in summer camps, and after school programs.
Long-term goals were generally related to improving student attitudes toward STEM and increasing student
interest in STEM majors and careers (Adamchuk, 2009; Duran et al., 2013; Javidi & Sheybani, 2010; Kampe &
Oppliger, 2011; Moskal et al., 2007; Nugent, Barket, White, & Grandgenettt, 2011; Stephen, Bracey, & Locke,
2012; Strautmann, 2011; Welch, 2010). Increased content knowledge in mathematics, science, and engineering
was a goal of several of the robotics programs, but whether or not goals were met was generally measured
through student self-reports (Adamchuk, 2009; Moskal et al., 2007; Nag et al., 2013). Students were provided
opportunities to improve 21st century skills, such as problem solving and collaboration, by using robotics to
solve the problems presented to them (Adamchuk, 2009; Duran & Sendag, 2012; Duran et al., 2013; Kampe &
Oppliger, 2011; Moskal et al., 2007; Nag et al., 2013; Nourbakhsh et al., 2005; Nugent et al., 2011; Welch,
2010). Increasing confidence in programming computers or handheld devices was a positive outcome of
robotics activities (Nourbakhsh et al., 2005), while some programs sought only to increase student use of and
confidence in the use of technologies in general (Duran & Sendag, 2012; Duran et al., 2013; Javidi & Sheybani,
2010; Kampe & Oppliger, 2013; Moskal et al., 2007; Nugent et al., 2011; Strautmann, 2011).
Computer Simulations. The use of simulations for training in the corporate world as well as for educational
applications has increased as the cost of computers has decreased. Simulations in the real world save time and
money while effectively training employees for potentially dangerous or complicated tasks. In the educational
environment, simulations provide experiences to students they would not normally be able to access. There
have been a few literature reviews on the ways simulations assist in student learning, but they were not focused
on STEM learning. In May 2013, a brief report was published, introducing an upcoming meta-analysis on
computer-based simulations for STEM learning; however, the final report is not yet available. The preliminary
findings indicated that simulations did improve student learning, and additional scaffolding increased the effect
(D’Angelo, Rutstein, Harris, Haertel, Bernard, & Borokhovski, 2013).
Nine of the 25 documents examined for this report described projects that used simulations of some type. Many
were not well characterized; however, one specifically mentioned robotics (Nag et al., 2013) and one involved
simulations in games (Sumners, Handron, & Jacobson, 2012). One project used a five-week simulation project
to address national standards for middle school students in persuasive writing, social studies, and science. The
simulation addressed water resources and solving a crisis in the availability of clean water. For students in both
Connecticut and Chicago, there were positive changes in self-efficacy in technology use. The project originated
with a single five-week simulation and has grown to a 14-week project with five different simulations (Brown
et al., 2010; Lawless, Brown, & Boyer, 2011).
Another simulation project was an action research project designed with a specific mathematical academic goal
in mind—to deepen understanding of scaling and proportional reasoning among middle school students.
Students participated in a four-week web-based interactive activity supported by group work and discussions.
Students believed the activities improved their understanding of scaling and proportions, increased their
confidence in their abilities to be successful in mathematics, and enjoyed the simulations (Chapman, 2012).
Texas A&M University 21
Simulations in the form of collaborative games were used to increase knowledge about the geological clock
(Johnson-Glenberg, Birchfield, Savvides, & Megowan-Romanowicz, 2011), to compare results of learning in
physical versus virtual hands-on science activities (Kalhr, Triona, & Williams, 2007), and to increase student
interest in STEM careers (Strautmann, 2011; Tan, Ngo, Chandrasekaran, & Cai, 2013).
Curricular units aligned with standards for high school biology and physical science included a summer
workshop for teachers, a small contingent of students for a summer pilot, and implementation in the classroom
with continued support for teachers. There were a number of difficulties encountered in such a project. First of
all, teachers needed to be familiar with and comfortable using the educational technologies, connecting the
activities with high school content, understanding nanotechnology as a different science rather than an addition
to existing sciences. They likewise required access to download necessary software on classroom computers.
Overall, teachers reported increased comfort levels with technology, but students did not (Yoon & Liu, 2010).
Handheld Technology. Besides the handheld calculator, many projects described in the artifacts collected used
other handheld devices that worked with either calculators or computers to collect data. The handheld
technologies used included cameras, motion sensors, various types of probes, global positioning systems (GPS),
geographic information systems (GIS), and other data collection devices. Often the handheld devices were used
to collect data to be analyzed on the graphing calculator or computer. Many projects were not specific as to how
and through what means data were analyzed, but the authors did state that they were using GPS or GIS devices
or other devices to collect information about the environment, such as conditions in the water or the air.
Among the artifacts that discussed the use of handheld technology, all but two also included robotics,
programming, or both. The projects that involved robotics with handheld devices focused on increasing student
interest in STEM subjects and/or STEM majors and careers. In addition, students had opportunities to improve
21st century skills, particularly problem solving and collaboration (Adamchuk et al., 2009; Kampe & Oppliger,
2011; Moskal et al., 2007; Stephen et al., 2012). Several studies included providing students with experience in
programming as one of their goals (Adamchuk et al., 2009; Hotaling et al., 2012; Moskal et al., 2007).
In one program, students first constructed a set of sensors from common electronics components, as teachers led
them through the science and mathematics principles necessary to build the sensors. They then tested the
sensors, programmed them, and used them to collect data to monitor water quality. Later, they used
programming skills to collect data and send it wirelessly to computerized sensor stations and formed a wireless
sensor network. Teachers were provided with 120 hours of PD to support the implementation of the integrated
STEM curriculum (Hotaling et al., 2012).
The use of motion sensors to create position-time, velocity-time, and acceleration-time graphs provided
interactive learning for students through visualization of science and mathematics concepts. Students gained
more content knowledge by use of the open source SmartGraphs software, and teacher experience with the
sensors and software contributed to even greater gains (Kay, Zucker, & Staudt, 2013).
The development of the Mobile Application Development for Science (MAD Science) curriculum centered
around using sensors to gather and analyze data from the environment. The program was designed for middle
school students in an after-school program. Students collected data samples related to a civic problem in the
community, analyzed the results, and presented their findings. The main goal of the program was to increase
student engagement and continued interest in science and technology (Heggen et al., 2012).
Texas A&M University 22
Programming. Seven of the nine articles that mentioned programming used it in connection with a robotics
project, and those were discussed briefly in the section on robotics. One of the remaining articles, where
students constructed sensors as well as programming them, was described in the previous section (Hotaling et
al., 2012). Another study described a one-week summer music technology program in which students worked
with computer-based instruments. They built a speaker and learned about sound transduction, sound waves and
sinusoidal function, frequencies and the inverse relationship to wave length, and computerized interfaces with
music. The purpose was to engage and interest students under-represented in STEM through music, an integral
part of their lives (Kim et al., 2011).
Other Technologies. One artifact involved a more traditional use of technology through computer-aided
instruction. Rather than just using the computer instruction to directly teach content, the system was used to
confront students with misconceptions about decimal numbers. Feedback was provided for wrong answers to
assist students in recognizing illogical concepts that they held. Students’ understanding and use of decimal
numbers improved following the instruction, and the retention of knowledge was high (Huang, Liu, & Shiu,
2008).
Another project’s goal was to increase middle school students’ interest in STEM careers by providing
information about what STEM professionals do in their jobs. Video interviews of STEM professionals were
created and edited for appeal to teenagers and were shown over an eight-week period. STEM career interests
were measured before, after half of the videos were shown, and after all of the videos were shown. The effect
was small but positive, and researchers noted that combining the videos with other methods might have
produced stronger results (Wyss, Heulskamp, & Siebert, 2012).
Findings. Of the technologies described in the 25 artifacts, robotics was used most frequently; however, this
type of technology was used only within informal settings, not in secondary classrooms. Many other types of
technologies were incorporated into the robotics after school programs, and summer camps and competitions,
such as simulations, hand-held devices, and programming. Simulations were the second most frequently used
technology application, providing virtual access to real-life situations and games for learning. Technology use
enabled students to demonstrate positive gains in content knowledge, enhance technology related skills,
experience a variety of teaching strategies, contemplate entering STEM majors or careers, become interested in
and enjoy STEM-related subjects, and develop 21st century skills.
Conclusions. There were considerably more studies that had stated goals of engaging students in STEM
learning, growth in knowledge and comfort with various technologies, increasing interest in STEM studies and
careers, and improving student attitudes about STEM courses than there were with main goals to increase
students’ mathematics or science content knowledge. In general, long-term projects working on relevant
problems produced positive results for student interest in STEM majors and careers, but these projects were
conducted in informal environments, usually with voluntary involvement. For studies that addressed content
knowledge, the strongest results were seen in science content, with fewer gains in mathematics content.
For projects that involved STEM teaching and learning in the formal school setting, teacher PD was generally
addressed. Teacher content knowledge seemed to be the most critical piece in success, but that knowledge was
minimally useful without the pedagogical knowledge to implement the integrated STEM curriculum. At times,
the limitations in the school settings to access and fully implement the necessary technology diminished the
success of the project. With a high level of fidelity of implementation, goals related to STEM teaching and
learning were realized.

Category 5: School Factors Influencing STEM Learning
Coding Artifacts. Ten artifacts of the meta-synthesis were based on school factors (see Table 5). The general
methodological choice was quasi-experimental. The samples were small, highly idiosyncratic, and without clear
criteria related to any modern reporting practices (American Educational Research Association, 2006; American
Psychological Association, 2001). Three studies used nationally representative data while the rest used
convenience samples (Legewie & DiPrete, 2012; Lynch, 2009; Maltese, 2008). Of the studies using convenient
sampling, only two included sufficient information about the sample in hand to determine a population and
none explicitly compared their sample to the population. The study durations were generally short with low
intensity. The studies ranged from 90 minutes to 16 hours and only one study included the administered survey,
while most studies did not use outcome measures but relied on informal interviews or researcher notes. Of the
four studies that incorporated some type of curriculum, only one reported on providing PD for teachers and
none of the studies included student-learning outcomes.
Conclusions. Among those factors, course taking in high school, particularly in 11th and 12th grades, were
highly associated with earning a STEM degree in 5 years. Students who took a calculus course were most
likely to earn a STEM degree. With regard to taking science courses, most students earning a STEM degree had
taken physics as compared to only 9% who took chemistry alone (Tyson et al., 2007). Contradictorily, a
nationally representative sample indicated that when controlling for student characteristics, neither parental nor
high school characteristics had any statistically significant effect on post-secondary STEM enrollment. Rather,
gender, race, and science and math achievement and interest were the strongest predictive factors in STEM
enrollment when holding parental and school characteristics constant. Once students entered post-secondary
education, Blacks, Hispanics, and Asians were all more likely to major in an NCES-defined STEM field than
Whites (Lynch, 2009).
The results for course taking were different for males and females. Females took more rigorous mathematics
and science courses in high school. However, only half the number of females went on to earn a STEM degree
as compared to males (Legewie & DiPrete, 2012; Tyson et al., 2007). This trend was persistent regardless of
which combination of high school mathematics and science courses were taken (Tyson et al., 2007). This was
aligned with students who had a strong identity in a particular field and those who also had a strong penchant to
claim an interest in a STEM field (Hazari, Sonnert, Sadler, & Shanahan, 2010).
There were apparent differences by ethnicity, shedding new light on the issues of equity. Nearly 33% of Asian-
American students earned a STEM degree, only 12.8% of White students did so, but Hispanic and Black
students tended to perform on par with their counterparts once in college. When considering SES, students on
free lunch in high school who obtained a baccalaureate degree were more likely to be in STEM fields than those
students who paid for their lunch (Tyson, et al., 2007).
Whole school STEM programs that applied the engineering design process and addressed Standards for
Technological Literacy developed by the International Technology and Engineering Educators Association
(ITEEA) (Goodwin, Brawley, Ferguson, Price, & Whitehair, 2013) achieved about on par with non-whole
STEM schools. Whole school programs required PD because teachers had little or no prior experience with
engineering design or the applications of various technologies. After two four-day PD sessions that included
hands-on experience with tools, electronics, materials selection, and STEM lesson planning, students were
engaged and enthusiastic, and all teachers incorporated the engineering design process, Standards for
Texas A&M University 24
Technological Literacy, and cross-curricular activities on a regular basis. Students indicated that the Whole-
School STEM program helped them learn, increased their interest in school, and increased the frequency with
which they used STEM tools. In particular, underachieving students were particularly responsive to STEM
activities, and demonstrated levels of leadership, enthusiasm, and success that were much higher than in other
academic subjects. Building a STEM identity was within the capabilities of the teacher by focusing the class on
conceptual understanding, conducting labs that addressed students’ beliefs about the world, discussing currently
relevant science and the benefits of being a scientist, and encouraging students to take science classes. The first
finding was that a conceptual understanding focus was positively related to physics identity, dovetailed with a
host of other research that found a link between physics conceptual understanding and performance (Hazari et
al., 2010).
Other STEM Interventions
The use of attitudinal and dispositional change agents was the dominant factor represented. Students who had
the disposition or inclination to consider post-secondary STEM matriculation were more likely to have a
positive attitude toward a STEM career after voluntarily participating in 16 hours per year of workshops
conducted by university STEM professors (Cantrell et al., 2009).
The following was the original question driving this literature review: What are the promising practices in
middle and high-school STEM teaching and learning? The most promising practice identified was increasing
teacher content knowledge, followed by improving teachers’ pedagogical practices for STEM teaching and
learning. Many of the studies focused on students’ STEM learning followed by a PD event for teachers that
focused on teacher content knowledge, reform-based STEM teaching practices, and/or STEM research
experience for teachers. Five artifacts reviewed established a positive correlation between teacher content
knowledge and student performance. However, it was difficult to attribute student performance solely to teacher
content knowledge. Direct empirical evidence of this relationship was demonstrated in one of the five studies
(Hotaling et al., 2012). Teacher content knowledge had a substantial impact on student outcomes.
Promising pedagogical reform-based practices included PBL, problem-based learning, inquiry-based learning,
engineering design, hands-on practices, and the legacy cycle. Of these reform-based practices, inquiry was the
most often used followed by engineering design. One of the main goals of the reform-based teaching and
learning strategies for 12 out of 23 artifacts appeared to be increasing students’ content knowledge, and—for
the most part—student content knowledge was enhanced in programs focused on that objective. Of the 12
artifacts focused on improving student content knowledge, ten showed a positive effect. Of those ten studies,
four utilized inquiry, three utilized engineering design, one used PBL, one used the legacy cycle, and one
focused on hands-on strategies. Inquiry represents the most often studied reform-based practice, and these
results indicate that it may also be the most promising.
However, caution is necessary. Inquiry was poorly defined in several of the studies, and it is sometimes used as
a catchall term. In addition, even though it may indicate average positive gains in content knowledge, prior
research has shown these gains to be highly heterogeneous with different outcomes for low versus high
performers. In other words, students struggling with STEM courses do not seem to perform as well with inquiry
as students with a high interest or aptitude for STEM (Kirschner et al., 2006; Tai & Sadler, 2009). Keeping in
mind the need for quality differentiated instruction, reviewers were especially interested in promising practices
for less able and less motivated learners. Engineering design appears to show the most promise in this area with
research indicating that low achieving African Americans gained substantially using this reform-based practice
(Mehalik et al., 2008).
Texas A&M University 25
Considerably more of the artifacts reviewed had stated goals other than increasing students’ mathematics or
science content knowledge. Most of those reviewed had the following non-content related objectives: engaging
students in STEM learning, expanding students’ knowledge and/or comfort with various technologies,
increasing interest in STEM studies and careers, and improving attitudes about STEM. In general, long-term
projects working on relevant problems produced positive results for student interest in STEM majors and
careers, but these projects were most often conducted in informal environments, usually with voluntary
involvement. Among the 22 items reviewed related to informal STEM learning, findings support the use of
informal learning environments to enhance content knowledge, skills, attitudes, and interest for STEM.
However, caution is again necessary. Equity issues related to “closing the gaps” involve strategies for access to
equal participation as well as strategies for access to equal success. Even though STEM summer camp
opportunities and after school activities attempt to recruit underrepresented and/or low achieving students, the
reality is that access to informal STEM activities is often based on students’ expressed interests, prior academic
achievement, teacher recommendation, time availability and flexibility, travel availability and flexibility, and
overall levels of ambition/motivation. It is difficult, then, to attribute success to an elective program when
factors such as teachers’ expectations and student motivation have not been controlled for. Promising practices
that may be gleaned from the studies on informal education could be transitioned and adopted in formal
education settings such as the typical classroom. These practices include students identifying and solving
authentic problems, content-focused field trips, interactions with experts in STEM fields, and long-term projects
that require true STEM integration terminating with results and conclusions.
For projects that involved STEM teaching and learning in the formal school setting, teacher PD was generally
addressed. Teacher content knowledge seemed to be the most critical piece in success, but that knowledge was
minimally useful without the pedagogical knowledge to implement the integrated STEM curriculum. At times,
the limitations in the school settings to access and fully implement the necessary technology diminished the
success of the project. With a high level of fidelity of implementation, goals related to STEM teaching and
learning were realized.
