Presenter: Chuong Chantha
Research Background - Cambodia has experienced civil wars for several decades. The most
serious one is in Pol Pot regime.
- Because human resource is vital for the development of the country; therefore, education sector was set up as one among the priority goals of Cambodian Government Rectangular Strategy .
- To improve the quality of human resource
- So, Teacher Training Center (TTCs) have been taken into account (MoEYS). Particularly, many NGOs and partnerships, such as JICA, VVOB, SCN, SVA, and so on are participating to develop TTCs which mainly emphasized on science education.
- Contextually, the goal of science education is to develop scientific skills or process skills (Baseline survey, 2009)

What is Science Process Skills (SPS)?
SPS are the methods of investigation used for solving problems (Campbell, 1979) SPS are the valuable aspect of science (Burns et al., 1985) SPS are the intellectual skills practiced in scientific situation (Ramig et al., 1995) SPS are the ways to solving problem (Lumbantobing, 2004) SPS are the scientific method, scientific thinking and critical thinking (MONICA, 2005) SPS are the things that scientists do when they study and investigate (Rezba et al., 2007). SPS provide students to learn by doing, experiencing and associating science subject with
daily life. SPS are skills which make the learning in Science and Technology lesson easy, develop students’ curiosity and make them active, introduce the laboratory atmosphere by driving the students to make research and facilitate to convey the learning from Science and Technology lesson to the real life (OZTURK et al., 2010)
3 Science Process Skills are the key to encourage students to inquire something
new in learning science to reach technological society
Research Background
Categories and SPS components
Science process skills were divided into three groups: basic, intermediate, and advanced levels (Charlesworth and Lind, 1995; Donmez and Azizoglu, 2010; Farsakoglu, Sahin, Karsli, Akpinar, & Ultay, 2008)
Abdullah, 2010; Lumbantobing, 2004; Paul, 1970; Rezba, Sprague, McDonnough, & Matkins, 2007; STEPSAM2, 2009; SAPA, 1975; pointed out that, there are two main groups of SPS: those are basic science process skills and integrated science process skills.

Research Background
Problem Statement
7
Fortunately, from 2009 up to 2012, STEPSAM2 project had provided training to TTCs which
focused on Lesson Study and Inquiry-Based Lesson in the concept of providing science process skills
But until 2009, science trainers and trainees still showed their constraint on “scientific skills or process skills” (STEPSAM2, 2009; MAEDA et al., 2006)
Science process skills were introduced into Cambodian
science education since 1999 in grade 4, 2000 in grade 5 and
2001 in grade 6 guidance books. So far, there is no any studies to evaluate the
level of science process skills of trainees, therefore
I want to conduct a research on the field
This study aims:
- To examine the extent of science process skills of elementary teacher trainees in PTTCs in Cambodia
- To identify the differences in science process skills across PTTCs, gender and educational levels.
★ PTTCs: Provincial Teacher Training Colleges

Objectives
Research Question
To achieve these objectives, this study was guided by the following questions:
1)- To what extent do elementary teacher trainees in PTTCs in
Cambodia possess science process skills?
2)- Is there any significant difference in science process skills across
PTTCs, gender as well as educational levels?

Summary of literature review
Regions, Gender, and Education Levels
11
Regions: There was significant difference between region and region (Nevin et al.,
2010; Radford et al., 1992)
Gender: There was a significant difference between gender (Aydinli et al., 2011;
Cakir et al., 2010; DONMEZ et al., 2010).
However, there was no significant difference between female and male students’ science process skills levels (Duran et al., 2010; OZTURK et al., 2010, CHAGUNA and YANGO, 2008)
Educational Levels: Significant difference on grade levels or educational levels (Duran et al.,
2010; Aydinli et al., 2011; Radford et al., 1992, Dokme et al., 2009). In contrast, the achievement on the process skill subtests is quite
uniform at all grade levels (CHAN, 2002; PADILLA and OKEY, 1983)

Level of science process skills by Educational Levels
Discussion In this study, the result showed that the elementary teacher trainees were likely to get above 50% on observing, classifying, inferring, measuring and predicting skill but below average in case of communicating skill. This is because of during student time, they are seemingly not allowed to express or communicate much during class activity.
Elementary teacher trainees were likely to get below average score of integrated science process skills. Specifically, trainees tended to have the lowest score in defining operationally. Actually, competence in defining operationally is crucially important in the precise use of terms in communication about investigations and experiments (Paul, 1970). Logically, trainees were weak in communicating skill so they were also weak in defining operationally too.
The level of science process skills varied by PTTCs. This implied that the quality of PTTCs in this study might be different from one to another.
26
Discussion Based on my interview with PTTC’s directors, science trainers, Japanese volunteers, and STEPSAM2 coordinator, the idea below explained why science process skills among trainees were different across the PTTCs: Trainers’ motivation, absence and ability “……. Our PTTC got a good result because the trainers have motivation to teacher, come all the time, and they always develop their ability…..” Mr. KOIZUMI Fumiasa, Ms. MOTOE; Japanese volunteers, Mr. Set Seng, STEPSAM2 coordinator Schools’ sources “……..improvisation is very important. Without them I/they don’t know how to teach science….” Mr. Lim Sokha, science trainer in Takeo PTTC, Mr. Set Seng Assistance by Japanese volunteers “……. He help me a lots. He made teaching materials, teach us how to use it and always give me some ideas….” Mr. Koa Kha, science trainer in Prey Veng PTTC, Mr. Lim Sokha Experimenting “…… He always teaches student using experiment all the time…..” Mr. Koa Kha, Mr. KOIZUMI Fumiasa, Management “……Management is very important……” Mr. Set Seng, Ms. Motoe Projects “…… Project (example: STEPSAM project, Hiroshima Project, VSA…) helps us very much to improve our ability” Mr. Set Seng, Mr. Lim Sokha, Mr. Horng Sam Oeun, Takeo PTTC vice director. 27
Conclusion
28
Elementary teacher trainees possess higher ability in basic science process skills than integrated science process skills. Among all the basic science process skills, elementary teacher trainees
have high ability in observing skill and low ability in communicating skill. Anyway, among all the integrated science process skills, elementary
teacher trainees have the lowest ability in operational definition.
The level of science process skills of trainees differs across PTTCs. Trainees from Takeo and Prey Veng PTTC possess the highest ability in both basis and integrated science process skills.
However, the level of science process skills of trainees were not significantly different across gender as well as educational levels
Implications
Integrated science process skills should be reconsidered in the curriculum and teaching process
PTTC’s inputs (such as trainer’s motivation, absence and ability, school’s sources, number of experimentations, management) need to be given more attention
Other project collaboration (Japanese volunteers, STEPSAM project, Hiroshima project) should be more focused
29
Should cover other PTTCs
Should find out the reason why elementary teacher trainees had low ability in some components
Quantitative research should be conducted to verify the second finding
