OVERVIEW

The State Board for Educator Certification (SBEC) has approved Texas educator standards thatdelineate what the beginning educator should know and be able to do. These standards, whichare based on the state-required curriculum for students — the Texas Essential Knowledge and Skills(TEKS) — form the basis for the Texas Examinations of Educator Standards® (TExES®) program.This initiative, administered by Texas Education Agency (TEA), will affect all areas of Texaseducation — from the more than 170 approved Texas Educator Preparation Programs (EPPs) to themore than 7,000 Texas school campuses. This standards-based system reflects SBEC’s commitmentto help align Texas education from kindergarten through college. SBEC and TEA’s roles in thisK–16 initiative will ensure that newly certified Texas educators have the essential knowledge andskills to teach the TEKS to the state’s public school students.

This manual is designed to help examinees prepare for the TExES test in this field. Its purpose is tofamiliarize examinees with the competencies to be tested, test question formats and pertinent studyresources. EPP staff may also find this information useful as they help examinees prepare for careersas Texas educators.

USING THE TEST FRAMEWORK

The Texas Examinations of Educator Standards (TExES) tests measure the content knowledgerequired of an entry-level educator in a particular field in Texas public schools. This manual isdesigned to guide your preparation by helping you become familiar with the material to be coveredon the test you are planning to take, identify areas where you feel you may be weak and increaseyour knowledge in those areas by helping you design a study plan.

When preparing for this test, you should focus on the competencies and descriptivestatements, which delineate the content that is eligible for testing. A portion of the contentis represented in the sample questions that are included in this manual. These test questionsrepresent only a sampling of questions. Thus, your test preparation should focus on thecompetencies and descriptive statements and not simply on the sample questions.

ORGANIZATION OF THE TEXES TEST FRAMEWORK

The test framework is based on the educator standards for this field.

The content covered by this test is organized into broad areas of content called domains. Eachdomain covers one or more of the educator standards for this field. Within each domain, the contentis further defined by a set of competencies. Each competency is composed of two major parts:

1. the competency statement, which broadly defines what an entry-level educator in this fieldin Texas public schools should know and be able to do, and

2. the descriptive statements, which describe in greater detail the knowledge and skills eligiblefor testing.

The educator standards being assessed within each domain are listed for reference at the beginningof the test framework, which begins on page 12. These are followed by a complete set of theframework’s competencies and descriptive statements.

THE TEXES TESTS FOR TEXAS TEACHERS

As required by the Texas Education Code §21.048, successful performance on educator certificationexaminations is required for the issuance of a Texas educator certificate. Each TExES test is acriterion-referenced examination designed to measure the knowledge and skills delineated in thecorresponding TExES test framework. Each test framework is based on standards that weredeveloped by Texas educators and other education stakeholders.

Each TExES test is designed to measure the requisite knowledge and skills that an entry-leveleducator in this field in Texas public schools must possess. The tests include both individual(stand-alone) test questions and questions that are arranged in clustered sets based on real-worldsituations faced by educators.

DEVELOPMENT OF THE NEW TExES TESTS

Committees of Texas educators and members of the community guide the development of thenew TExES tests by participating in each stage of the test development process. These workingcommittees are composed of Texas educators from public and charter schools, university and EPPfaculty, education service center staff, representatives from professional educator organizations,content experts and members of the business community. The committees are balanced in terms ofposition, affiliation, years of experience, ethnicity, gender and geographical location. The committeemembership is rotated during the development process so that numerous Texas stakeholders may beactively involved. The steps in the process to develop the TExES tests are described below.

1. Develop Standards. Committees are established to recommend what the beginning educatorshould know and be able to do. Using the Texas Essential Knowledge and Skills (TEKS) asthe focal point, draft standards are prepared to define the knowledge and skills required of thebeginning educator.

2. Review Standards. Committees review and revise the draft standards. The revised draftstandards are then placed on the TEA website for public review and comment. Thesecomments are used to prepare a final draft of the standards that will be presented to the SBECBoard for discussion, the State Board of Education (SBOE) for review and comment and theSBEC Board for approval. Standards not based specifically on the TEKS, such as those forlibrarians and counselors, are proposed as rule by the SBEC Board; sent to the SBOE for its90-day review; and, if not rejected by the SBOE, adopted by the SBEC Board.

3. Develop Test Frameworks. Committees review and revise draft test frameworks that arebased on the standards. These frameworks outline the specific competencies to be measuredon the new TExES tests. Draft frameworks are not finalized until after the standards areapproved and the job analysis/content validation survey (see #4) is complete.

4. Conduct Job Analysis/Content Validation Surveys. A representative sample of Texaseducators who practice in or prepare individuals for each of the fields for which an educatorcertificate has been proposed are surveyed to determine the relative job importance of eachcompetency outlined in the test framework for that content area. Frameworks are revised asneeded following an analysis of the survey responses.

Page 13: 114 Math Science 4-8

5. Develop and Review New Test Questions. The test contractor develops draft questions thatare designed to measure the competencies described in the test framework. Committeesreview the newly developed test questions that have been written to reflect the competenciesin the new test framework. Committee members scrutinize the draft questions forappropriateness of content and difficulty; clarity; match to the competencies; and potentialethnic, gender and regional bias.

6. Conduct Pilot Test of New Test Questions. All of the newly developed test questions thathave been deemed acceptable by the question review committees are then administered to anappropriate sample of candidates for certification.

7. Review Pilot Test Data. Pilot test results are reviewed to ensure that the test questions arevalid, reliable and free from bias.

8. Administer TExES Tests. New TExES tests are constructed to reflect the competencies, andthe tests are administered to candidates for certification.

9. Set Passing Standard. A Standard Setting Committee convenes to review performance datafrom the initial administration of each new TExES test and to recommend a final passingstandard for that test. The SBEC Board considers this recommendation as it establishes apassing score on the test.

TAKING THE TEXES TEST AND RECEIVING SCORES

Please refer to the current TExES Registration Bulletin or the ETS TExES website atwww.texes.ets.org for information on test dates, test centers, fees, registration procedures andprogram policies.

Your score report will be available to you in your testing account on the ETS TExES onlineregistration system by 5 p.m. Central time on the score reporting date indicated in theRegistration Bulletin. The report will indicate whether you have passed the test and will include:

• A total test scaled score. Scaled scores are reported to allow for the comparison ofscores on the same content-area test taken on different test administration dates.The total scaled score is not the percentage of questions answered correctly and isnot determined by averaging the number of questions answered correctly in eachdomain.

– For all TExES tests, the score scale is 100–300 with a scaled score of 240 as theminimum passing score. This score represents the minimum level of competencyrequired to be an entry-level educator in this field in Texas public schools.

• Your performance in the major content domains of the test and in the specificcontent competencies of the test.

– This information may be useful in identifying strengths and weaknesses in yourcontent preparation and can be used for further study or for preparing to retake thetest. However, it is important to use caution when interpreting scores reported bydomain and competency as these scores are typically based on a smaller number ofitems than the total score and therefore may not be as reliable as the total score.

• A link to information to help you understand the score scale and interpret yourresults.

A score report will not be available to you if you are absent or choose to cancel your score.

For more information about scores or to access scores online, go to www.texes.ets.org.

APPROACHES TO ANSWERING MULTIPLE-CHOICE QUESTIONS

The purpose of this section is to describe multiple-choice question formats that you will see onthe Mathematics/Science 4–8 test and to suggest possible ways to approach thinking about andanswering the multiple-choice questions. However, these approaches are not intended to replacefamiliar test-taking strategies with which you are already comfortable and that work for you.

The Mathematics/Science 4–8 test is designed to include a total of 120 multiple-choice questions,out of which 100 are scored. The number of scored questions will not vary; however, the number ofquestions that are not scored may vary in the actual test. Your final scaled score will be based onlyon scored questions. The questions that are not scored are being pilot tested in order to collectinformation about how these questions will perform under actual testing conditions. These questionsare not identified on the test.

All multiple-choice questions on this test are designed to assess your knowledge of the contentdescribed in the test framework. In most cases, you are expected to demonstrate more than just yourability to recall factual information. You may be asked to solve a multistep problem; analyze andinterpret mathematical information in a variety of formats; determine a mathematical function thatmodels a given situation; or supply information needed to prove a mathematical statement.

When you are ready to respond to a multiple-choice question, you must choose one of four answeroptions labeled A, B, C and D. Leave no questions unanswered. Nothing is subtracted from yourscore if you answer a question incorrectly. Questions for which you mark no answer are counted asincorrect. Your score will be determined by the number of questions for which you select the bestanswer.

Calculators. Scientific calculators will be provided at the test center. See the TExES RegistrationBulletin for the brand and model of the calculator that will be available.

Definitions and Formulas. A set of definitions and formulas will be provided as part of the test. Acopy of those definitions and formulas is provided in Chapter 5 of this preparation manual.

On the following pages, you will find descriptions of these commonly used question formats, alongwith suggested approaches for responding to each type of question. In the actual testing situation,you may write on the scratch paper provided at the testing center. Your final response must beselected on the computer.

SINGLE QUESTIONS

In the single-question format, a problem is presented as a direct question or an incomplete statement,and four answer options appear below the question. The following question is an example of thistype. It tests knowledge of Mathematics/Science 4–8 Competency 010: The teacher analyzes theproperties of two- and three-dimensional figures.

EXAMPLE 1

1. The Great Pyramid at Giza is approximately 150 meters high and has a square baseapproximately 230 meters on a side. What is the approximate area of a horizontal crosssection of the pyramid taken 50 meters above its base?

A. 5,880 square meters

B. 11,760 square meters

C. 23,510 square meters

D. 35,270 square meters

SUGGESTED APPROACH

Read the question carefully and critically. Think about what it is asking and the situation it isdescribing. Eliminate any obviously wrong answers, select the correct answer choice and markyour answer.

TExES Preparation Manual — Mathematics/Science 4–8 41

SUCCEEDING ON MULTIPLE-CHOICE QUESTIONS

Page 46: 114 Math Science 4-8

The horizontal cross section will be a square in the plane parallel to the base of the pyramid and50 meters above it. In order to estimate the area of the cross section, you will need to know theapproximate length of one of its sides. This can be calculated using your knowledge of proportionsand the properties of similar geometric figures. In solving problems that involve geometry, drawinga diagram is often helpful.

The figure shows a vertical cross section through the center of the square base of the pyramidperpendicular to a side of the base. The measurements given in the test question have beentransferred to the diagram. Notice that since CG + GF = 150, and it is given that GF = 50, thenCG = 100. You must find BD, the length of the sides of the square cross section. Also note that�CBD and �CAE are similar because they have two angles whose measures are equal; they share�C and the measure of �B is equal to the measure of �A since they are corresponding anglesformed by a transversal and two parallel lines. Because the two triangles are similar, their altitudes

and sides must be proportional and you can write: CGCF

BDAE

= . Now substitute the values for the

lengths of the line segments to get 100150 230

= BD. Solving this gives BD = 153.33. Since the horizontal

cross section is a square, its area is the square of the length of BD, or (153.33)2 = 23,511.11 square feet.Now look at the response options. The correct response is option C, rounded to the nearest tensquare meters.

Setting up the proportion incorrectly as 50150 230

= BD and using this value for the side of the cross

section leads to option A. Option B results from assuming that the cross section is an isosceles

right triangle instead of a square, and option D comes from assuming that the area of the cross

section is 100150

= of the area of the base of the pyramid.

EXAMPLE 2

The following questions tests knowledge of Mathematics/Science 4–8 Competency 030: The teacherunderstands the structure and function of living things.

2. Use the diagram below to answer the question that follows.

On a class field trip, students encounter some brightly colored shelf-life structures attachedto the trunk of a dead tree. Which of the following is the best description of how thisorganism obtains matter and energy from the environment?

A. It obtains energy from the dead wood and absorbs carbon dioxide and water vaporfrom the air

B. It obtains energy from the sunlight, absorbs carbon from the dead wood and obtainswater vapor from the air

C. It obtains energy from sunlight and obtains carbon and water from the dead wood

D. It obtains energy, carbon and water from the dead wood

SUGGESTED APPROACH

Read the question carefully and critically. Think about what it is asking and the situation it isdescribing. Eliminate any obviously wrong answers, select the correct answer choice and markyour answer.

As you read this question, it should be clear from the diagram that the shelf-like structures arefungi. Think about the characteristics that distinguish fungi from other organisms. One importantdifference is how fungi obtain energy and nutrients. Unlike plants, fungi lack chlorophyll and donot photosynthesize, obtaining all their energy and nutrients from the absorption of organic matter.

Now look at the response options. The correct response is option D. All other options refer to somepart of the photosynthetic cycle and therefore do not pertain to fungi.

Sometypes of stimulus material included on the test are geometric diagrams, charts, data tables, graphs,equations, passages, samples of student work and descriptions of classroom situations. In such cases,you will generally be given information followed by an event to analyze, a problem to solve or adecision to make.

You can use several different approaches to respond to these types of questions. Some commonlyused strategies are listed below.

Strategy 1 Skim the stimulus material to understand its purpose, its arrangement and/or itscontent. Then read the question and refer again to the stimulus material to obtainthe specific information you need to answer the question.

Strategy 2 Read the question before considering the stimulus material. The theory behindthis strategy is that the content of the question will help you identify the purposeof the stimulus material and locate the information you need to answer thequestion.

Strategy 3 Use a combination of both strategies; apply the “read the stimulus first” strategywith shorter, more familiar stimuli and the “read the question first” strategy withlonger, more complex or less familiar stimuli. You can experiment with thesample questions in this manual and then use the strategy with which you aremost comfortable when you take the actual test.

Whether you read the stimulus before or after you read the question, you should read it carefully andcritically.

As you consider questions set in educational contexts, try to enter into the identified teacher’s frameof mind and use that teacher’s point of view to answer the questions that accompany the stimulus. Besure to consider the questions in terms of only the information provided in the stimulus — not interms of your own class experiences or individual students you may have known.

EXAMPLE 1

First read the stimulus (a description of the concept being studied).

Use the diagram and the information below to answer the two questions that follow.

Students in a math class are investigating concepts related to motion in one dimension. Thevelocity-versus-time graph shows the velocity of a student walking in a straight line, collectedat one-second intervals over a period of nine seconds.

Now you are prepared to address the first of the two questions associated with this stimulus. The firstquestion measures Mathematics/Science 4–8 Competency 007: The teacher uses and understands theconceptual foundations of calculus related to topics in middle school mathematics.

Which of the following methods could be used to estimate the student’s acceleration betweent = 3 and t = 5 seconds?

A. Find the average of the velocities at t = 3 and t = 5 seconds

B. Find the equation of the curve that best fits the data and evaluate it at t = 4 seconds

C. Find the length of the line connecting the velocities between t = 3 and t = 5 seconds

D. Find the slope of the line connecting the velocities at t = 3 and t = 5 seconds

SUGGESTED APPROACH

You are asked to estimate the acceleration of the student between 3 and 5 seconds, that is, theaverage acceleration over this time period. Average acceleration is the rate of change of velocity with

respect to time, ΔΔvt

vt

= −−

2 1

12

vt

. Therefore, divide the difference in the velocities at 5 and 3 seconds

by the total time elapsed, here 5 – 3 = 2 seconds. You should recognize this expression as representingthe slope of a line connecting two points, or the difference in the y-coordinates divided by the differencein the x-coordinates. Therefore, option D is correct.

Page 50: 114 Math Science 4-8

Option A finds the average velocity in the time interval, while option B finds an expression forvelocity as a function of time and interpolates how fast the student is moving at t = 4s. Option Cdetermines the length of the curve and has no physical significance.

Now you are ready to answer the next question. The second question also measures Mathematics/Science 4–8 Competency 007: The teacher uses and understands the conceptual foundations ofcalculus related to topics in middle school mathematics.

Which of the following methods could be used to estimate the total distance the student hastraveled between t = 0 and t = 5 seconds?

A. Find the median value of the velocities from t = 0 to t = 5 seconds, inclusive

B. Find the ratio of the velocities at t = 0 and t = 5 seconds

C. Find the area under the curve between t = 0 and t = 5 seconds

D. Find the average value of the velocity-over-time ratios for t = 0 and t = 5 seconds

SUGGESTED APPROACH

In order to calculate the distance traveled by the student during a particular time interval, multiplythe rate of travel by the length of time the student is moving; in other words, d = rt where drepresents distance, r represents rate (velocity), and t represents time. For example, during theinterval from t = 1 to t = 2 seconds, multiply the average velocity during the interval, approximately

0 25. ms ,by the length of the interval, 2 – 1 = 1 second. This can be represented geometrically by the area

of the rectangle of height = 0 25. ms , and base = 1s under the curve between t = 1s and t = 2s. To get

an estimate of the total distance traveled by the student, you need to sum the distance traveled duringeach of the one-second intervals from 0 through 5 seconds. This is approximately equal tothe area under the curve from t = 0 to t = 5 seconds. Therefore option C is correct.

Option A gives the median value for the velocity, which by itself cannot be used to estimate thedistance traveled by the student. The ratio of the velocities (option B) is not helpful in determiningthe total distance covered. Finding the average of the velocities at t = 0 and t = 5 (option D) is not byitself sufficient for calculating the distance traveled between those times.

EXAMPLE 2

First read the stimulus (a diagram of a stratigraphic section of rock).

Use the illustration below to answer the two questions that follow.

Now you are prepared to address the first of the two questions associated with this stimulus. The firstquestion measures Mathematics/Science 4–8 Competency 039: The teacher understands the historyof the earth system.

1. The igneous intrusion in the illustration has been dated to be 13 million years old, and thevolcanic ash layer has been dated to be 24 million years old. Which of the followingstatements about the ages of fossil X and fossil Y is most accurate?

A. Fossil X is younger than fossil Y, and both fossils are older than 24 million years old

B. Fossil X and fossil Y are both between 13 million and 24 million years old

C. Fossil X is older than fossil Y, and both fossils are younger than 13 million years old

D. Fossil X is younger than 13 million years old, and fossil Y is older than13 million years old

Page 52: 114 Math Science 4-8

SUGGESTED APPROACH

First examine the figure in the stimulus, noting the positions of the rock layers and the fossils labeledX and Y. You should be able to create a combined stratigraphy for the entire section by matching upthe pattern of layers on either side of the igneous intrusion. Locate the fossils labeled X and Y andconsider their relationship in the combined stratigraphy. It is clear that the two fossils are found inthe same stratigraphic layer located above the 24-million-year-old volcanic ash. Since they are abovethe volcanic ash layer, they must be younger than 24 million years old. Since the igneous intrusioncut through the layer in which the fossils were located 13 million years ago, both fossils must be atleast that old. Options A, C and D all state that one fossil is older than the other. Therefore, thecorrect response is option B.

Now you are ready to answer the next question. The second question also measures Mathematics/Science 4–8 Competency 039: The teacher understands the history of the earth system.

2. The discontinuity represented by the line labeled W in the illustration is most likely to be

A. a thrust fault.

B. an igneous intrusion.

C. a transverse fault.

D. an erosion surface.

SUGGESTED APPROACH

The second question requires you to recognize the characteristics of an unconformity in astratigraphic section. Note that the unconformity in the diagram cuts across several stratigraphiclayers and the igneous intrusion and that these are missing above the unconformity. Options A, B andC all refer to faults or intrusions. Faults result in the displacement of layers relative to other layers,while intrusions are characterized by the insertion of igneous rock through or between layers. In thiscase, the relationship of the layers to one another and to the sandstone above the unconformityindicates that the unconformity is an erosion surface and that option D is the correct response.

CLUSTERED QUESTIONS

You may have one or more questions related to a single stimulus. When you have at least twoquestions related to a single stimulus, the group of questions is called a cluster.

Use the passage below to answer the two questions that follow.

More than half of the world’s population cooks and heats with biomass fuels: wood, dung or cropwastes. Such fuels are inexpensive and available in remote rural locations, but they produce smokecontaining large amounts of soot and cancer-causing agents. Research in the United States andZimbabwe suggests that people could improve their health and their cooking efficiency by usingroots and gourds as fuels instead of other types of biomass. The roots and gourds, which are native toand grow well in arid climates, ignite more easily than other biomass fuels and give off virtually nosmoke. This cleaner burning is a result of more thorough and efficient combustion. More efficientburning means people burn fewer roots and gourds than they do other fuels.

THE DAY OF THE TEST

You should have ended your review a day or two before the actual test date. Many clichés you mayhave heard about the day of the test are true. You should:

• Be well rested.

• Take the appropriate identification document(s) with you to the test center (identificationrequirements are listed in the Registration Bulletin and on the ETS TExES website atwww.texes.ets.org).

• Take 3 or 4 well-sharpened soft-lead (No. 2 or HD) pencils with good erasers.

• Eat before you take the test.

• Be prepared to stand in line to check in or to wait while other test takers are beingchecked in.

• Stay calm. You can’t control the testing situation, but you can control yourself. Testadministrators are well trained and make every effort to provide uniform testingconditions, but don’t let it bother you if a test doesn’t start exactly on time. You will havethe necessary amount of time once it does start. Using the Reducing Test Anxiety bookletin the days before you test may be helpful in mentally and emotionally preparing yourselfto test. It is available free at www.texes.ets.org.

You can think of preparing for this test as training for an athletic event. Once you have trained,prepared and rested, give it everything you’ve got. Good luck.
