Question 1Component 1: Content Knowledge

A teacher gives a short exit ticket at the end of a lesson to see which students can apply the day's concept and then regroups the next day accordingly. This use of assessment is best described as

  1. norm-referenced, because it compares students' scores with one another
  2. formative, because the results are used to adjust instruction while learning is still in progress Correct answer.
  3. diagnostic, because it identifies students' prior knowledge before instruction
  4. summative, because it is administered at the end of a lesson

Explanation

Assessment is classified by purpose, not by length or timing alone. Formative assessment gathers evidence during learning so the teacher can adapt instruction; an exit ticket used to regroup students is a standard example. Summative assessment judges achievement after instruction, and diagnostic assessment precedes instruction.

Question 2Component 1: Content Knowledge

Vygotsky's zone of proximal development refers to the range of tasks that a learner

  1. can accomplish with guidance but not yet alone Correct answer.
  2. can complete only by trial and error
  3. is genetically predisposed to master at a fixed age
  4. can perform independently without any assistance

Explanation

The zone of proximal development is the gap between what a learner can do alone and what the learner can do with support from a more capable other. Instruction is most effective when aimed at this zone, where scaffolding makes the difference. Tasks fully mastered already or wholly beyond reach fall outside it.

Question 3Component 1: Content Knowledge

Which sequence matches the gradual release of responsibility model of instruction?

  1. Independent practice, guided practice, modeled instruction
  2. Modeled instruction, independent practice, guided practice
  3. Guided practice, modeled instruction, independent practice
  4. Modeled instruction, guided practice, independent practice Correct answer.

Explanation

Gradual release transfers cognitive responsibility from teacher to student in stages: the teacher models (I do), students work with support (we do), and students work alone (you do). Each stage depends on the support established in the one before it. Reordering the stages removes the scaffolding students need before independent work.

Question 4Component 1: Content Knowledge

After posing a higher-order question to the whole class, a teacher pauses several seconds before calling on anyone. The primary purpose of this pause is to

  1. shorten the amount of class time devoted to the question
  2. move the lesson along at a brisker pace
  3. give more students time to process the question and formulate a response Correct answer.
  4. ensure that only confident students volunteer an answer

Explanation

Wait time of roughly three to five seconds after a question increases response length, raises the number of students who participate, and improves the quality of reasoning. Higher-order questions require processing time, so a pause broadens access rather than slowing the lesson for its own sake.

Question 5Component 1: Content Knowledge

In Bandura's social cognitive theory, a student's self-efficacy is best described as the student's

  1. judgment about whether a particular outcome is desirable
  2. expectation that effort will be noticed by the teacher
  3. general intellectual ability as measured by an aptitude test
  4. belief about their own capability to succeed at a specific task Correct answer.

Explanation

Self-efficacy is a task-specific belief in one's capability to organize and execute the actions a task requires. It is learned from mastery experiences, vicarious models, persuasion, and physiological states, and it predicts effort and persistence. It is not a fixed trait or a measure of general ability.

Question 6Component 1: Content Knowledge

A teacher prepares three versions of a science investigation that address the same concept but vary in complexity, scaffolding, and pace. This adjustment primarily differentiates instruction by

  1. behavior
  2. readiness Correct answer.
  3. interest
  4. learning profile

Explanation

Tiered tasks hold the learning goal constant while varying difficulty and support, which is differentiation by readiness. Differentiation by interest builds choices around student passions, and differentiation by learning profile varies how students prefer to take in or show learning. Behavior is not one of the standard readiness, interest, and profile categories.

Question 7Component 1: Content Knowledge

Which learning objective is written in observable, measurable form?

  1. Students will develop a deep understanding of how ecosystems function.
  2. Students will list three stages of mitosis. Correct answer.
  3. Students will gain an appreciation for the importance of recycling in their community.
  4. Students will become familiar with the general process of photosynthesis.

Explanation

A measurable objective names an observable action and, ideally, a criterion for success. Verbs such as list, identify, compare, or explain can be observed and scored. Verbs such as appreciate, understand, or become familiar describe internal states that cannot be directly assessed.

Question 8Component 1: Content Knowledge

The most effective way to prevent most classroom disruptions is to

  1. arrange desks in rows facing the front of the room
  2. teach and rehearse routines early in the year Correct answer.
  3. post consequences for misbehavior where all students can see them
  4. respond to every disruption with a consistent verbal reprimand

Explanation

Strong management is largely preventive: expectations and routines are taught, practiced, and reinforced so students know exactly what to do. Predictable procedures reduce ambiguity, which is where most off-task behavior begins. Consequence systems and reprimands operate after disruption has already occurred.

Question 9Component 1: Content Knowledge

Which task best requires students to operate at the analyze level of Bloom's revised taxonomy?

  1. Rating the poem's overall quality on a five-point scale
  2. Reciting the definitions of imagery, rhyme scheme, and tone
  3. Breaking a poem into its imagery, rhyme scheme, and tone, and explaining how these parts work together Correct answer.
  4. Explaining in their own words what the poem is about

Explanation

Analyze involves breaking material into constituent parts and determining how the parts relate to one another and to an overall structure or purpose. Recalling definitions sits at remember, paraphrasing sits at understand, and judging quality sits at evaluate. Only the first task requires examining internal relationships.

Question 10Component 1: Content Knowledge

A test produces nearly the same score for the same student each time it is given, but it does not measure the knowledge it claims to measure. This test is

  1. reliable but not valid Correct answer.
  2. neither reliable nor valid
  3. valid but not reliable
  4. both reliable and valid

Explanation

Reliability concerns consistency of results across occasions, forms, or raters; validity concerns whether scores support the intended interpretations and uses. A test can be perfectly consistent while consistently measuring the wrong thing. Reliability is necessary but not sufficient for validity.

Question 11Component 1: Content Knowledge

An analytic rubric differs from a holistic rubric primarily in that an analytic rubric

  1. rates separate criteria or dimensions of a performance independently Correct answer.
  2. lists criteria without describing levels of quality
  3. is reserved for scoring standardized tests
  4. assigns a single overall score to a whole performance

Explanation

An analytic rubric divides a performance into separate criteria and scores each one, often with descriptive levels, which yields criterion-specific feedback. A holistic rubric instead assigns one overall judgment based on the total impression. Both can be used with classroom and standardized tasks.

Question 12Component 1: Content Knowledge

Under IDEA, the least restrictive environment requirement means that students with disabilities are

  1. always placed in general education classes regardless of individual needs
  2. educated with nondisabled peers to the maximum extent appropriate Correct answer.
  3. placed in separate settings until they meet grade-level benchmarks
  4. assigned to whatever setting their parents prefer

Explanation

Least restrictive environment requires that students with disabilities be educated alongside nondisabled peers to the maximum extent appropriate and be removed to separate settings only when supplementary aids and services cannot support success. Placement is an individualized team decision. It is a presumption of inclusion, not an absolute rule.

Question 13Component 1: Content Knowledge

Which statement accurately distinguishes Section 504 plans from IEPs?

  1. A 504 plan provides accommodations, whereas an IEP provides specialized instruction and related services. Correct answer.
  2. A 504 plan provides specialized instruction and related services, whereas an IEP provides only physical accommodations such as ramps and accessible seating.
  3. A 504 plan is written only for students who qualify for special education, whereas an IEP covers any student with a health condition.
  4. A 504 plan requires annual measurable goals monitored by a team, whereas an IEP provides only informal supports.

Explanation

Section 504 of the Rehabilitation Act prohibits discrimination and provides accommodations for students with a physical or mental impairment that substantially limits a major life activity. IDEA entitles eligible students to a free appropriate public education with specialized instruction, related services, and measurable goals. An IEP is more procedural and instructional; a 504 plan is typically narrower.

Question 14Component 1: Content Knowledge

A teacher lets students choose to read a text, listen to an audio version, or watch a captioned video of the same content. Which Universal Design for Learning principle does this choice primarily address?

  1. multiple means of action and expression
  2. multiple means of representation Correct answer.
  3. multiple means of assessment
  4. multiple means of engagement

Explanation

Offering the same content in text, audio, and captioned video provides multiple means of representation, which addresses how information is presented and perceived. Action and expression concerns how students demonstrate learning, and engagement concerns how motivation and interest are sustained.

Question 15Component 1: Content Knowledge

A newcomer English learner rarely speaks during her first months in class but follows directions and responds nonverbally. The most appropriate teacher response is to

  1. require her to answer aloud every day so she gets speaking practice
  2. continue providing comprehensible input, accept nonverbal responses, and gradually encourage participation Correct answer.
  3. excuse her from content instruction until her oral English develops
  4. refer her immediately for a speech-language evaluation

Explanation

A silent period is a normal phase of second language acquisition in which a learner comprehends and participates nonverbally before producing speech. Forcing production raises anxiety, while excluding the student from content denies access to the language and subject matter she needs to develop. Teachers should maintain comprehensible input and low-pressure participation.

Question 16Component 1: Content Knowledge

Which feedback is most likely to improve a student's argumentative writing?

  1. You're a natural writer - great job!
  2. Good work this time; keep it up.
  3. Your claim is clear, but two of your three evidence sentences don't support it, so revise those. Correct answer.
  4. B-minus. See me after class.

Explanation

Effective feedback is specific, goal-referenced, and actionable, telling the student what to do next relative to the target. Praise about ability and overall grades give little information about how to improve. This response names the problem and the revision needed.

Question 17Component 1: Content Knowledge

Metacognition in learning refers to a student's ability to

  1. retrieve information automatically without conscious effort
  2. monitor and regulate their own thinking and strategy use Correct answer.
  3. respond to rewards and punishments in the classroom
  4. process information through a single preferred learning style

Explanation

Metacognition includes knowledge about one's own thinking and the regulation of that thinking through planning, monitoring, and evaluating strategy use. It is deliberate and effortful, distinguishing it from automatic retrieval. The well-known claim that matching instruction to a single learning style improves learning is not supported by evidence.

Question 18Component 1: Content Knowledge

In cooperative learning, positive interdependence means that

  1. each member completes an independent portion with no shared accountability
  2. each student's success depends on the group's collective success Correct answer.
  3. the teacher assigns identical tasks to every group in the class
  4. group members compete with one another for a limited number of top grades

Explanation

Positive interdependence exists when students perceive that they can reach their goals only if the other group members also reach theirs, typically through shared goals, roles, and resources. It is paired with individual accountability so no member can coast. Competition and isolated work both remove the mutual dependence.

Question 19Component 1: Content Knowledge

A teacher learns that many families in her class run small businesses from home and builds a mathematics unit on pricing and profit around that experience. This practice best reflects

  1. norm-referenced curriculum planning
  2. a deficit-based approach to family involvement
  3. drawing on students' funds of knowledge Correct answer.
  4. a standardized test preparation strategy

Explanation

Funds of knowledge are the skills, practices, and bodies of knowledge that households and communities possess and transmit. Building instruction on those resources is a core element of culturally responsive teaching because it connects school content to students' lived experience. Deficit approaches, by contrast, treat home culture as a barrier.

Question 20Component 1: Content Knowledge

When students hold a persistent misconception about a science concept, the most effective instructional approach is to

  1. postpone the topic until students are older
  2. state that the idea is wrong and move on to new material
  3. elicit the misconception and present conflicting evidence students must reconcile Correct answer.
  4. repeat the correct explanation until it replaces the misconception

Explanation

Conceptual change requires that learners become dissatisfied with an existing idea, encounter an alternative that is intelligible and plausible, and find it useful. Simply restating the correct explanation often leaves the prior idea intact because students assimilate the new words into their old model. Confronting the misconception with discrepant evidence creates the need to restructure thinking.

Question 21Component 1: Content Knowledge

A class that previously read for pleasure is offered a prize for each book completed; afterward, students' voluntary reading declines. This outcome is best explained by

  1. the overjustification effect, in which expected rewards reduce intrinsic motivation Correct answer.
  2. observational learning, in which students imitate peers who read
  3. the spacing effect, in which practice is distributed over time
  4. negative reinforcement, in which a reward removes an unpleasant stimulus

Explanation

When an expected tangible reward is attached to an activity that was already intrinsically interesting, students may reinterpret their behavior as driven by the reward, and free-choice engagement often drops. This is the overjustification effect. It is most likely with expected, tangible, task-contingent rewards rather than praise or unexpected recognition.

Question 22Component 1: Content Knowledge

A student who learned to analyze arguments in history class applies the same reasoning to evaluate a scientific claim. This is an example of

  1. far transfer Correct answer.
  2. stimulus generalization
  3. rote learning
  4. near transfer

Explanation

Transfer is the application of prior learning to new situations. Far transfer occurs across substantially different contexts or domains, such as moving an argument-analysis skill from history to science, while near transfer stays within similar contexts and task demands. Far transfer is generally harder to achieve and depends on abstract, principled understanding.

Question 23Component 1: Content Knowledge

On a 40-item test, one item is answered correctly by most high-scoring students but by few low-scoring students. This item's discrimination index is

  1. negative, indicating high scorers did worse than low scorers
  2. positive and relatively high, indicating the item distinguishes strong from weak performance Correct answer.
  3. undefined, because discrimination cannot be computed for multiple-choice items
  4. near zero, indicating the item measures something unrelated to the test

Explanation

The discrimination index compares the proportion correct in a high-scoring group with the proportion correct in a low-scoring group. A large positive difference means the item separates students who know the content from those who do not, which is desirable. Near-zero values indicate no separation, and negative values indicate a flawed or miskeyed item.

Question 24Component 1: Content Knowledge

A student is fluent in everyday English conversation but struggles with academic reading and writing in content areas. This pattern is best explained by

  1. the difference between BICS, which develops in one to two years, and CALP, which takes five to seven years Correct answer.
  2. a lack of motivation to learn academic English
  3. the natural order hypothesis, in which grammar is acquired in a fixed sequence
  4. a receptive language disorder that requires a special education referral

Explanation

Basic interpersonal communicative skills are context-embedded and typically develop within one to two years, while cognitive academic language proficiency is context-reduced and demanding, usually taking five to seven years. A student can therefore sound fluent socially while still lacking the academic language needed for content-area reading and writing. This gap is a normal developmental difference, not a disorder or a motivational problem.

Question 25Component 1: Content Knowledge

A student earns a score of 70 on a test whose standard error of measurement is 4. Which interpretation is most defensible?

  1. The true score likely lies in a band around 70, roughly 66 to 74. Correct answer.
  2. The student performed better than 70 percent of the students in the norm group.
  3. The student's score would be identical on every possible parallel form of the test.
  4. The student's true score is exactly 70 because the test was standardized on a large norm group.

Explanation

The standard error of measurement estimates the variability of observed scores around a student's true score, so an observed score is best reported as a confidence band rather than a precise point. A band of roughly one standard error above and below the observed score is the conventional interpretation. Test standardization does not eliminate measurement error.

Question 26Component 1: Content Knowledge

A student with a disability receives extended time and a separate quiet room for unit tests. These supports are best classified as

  1. remediations that reteach missing skills
  2. interventions that replace core instruction
  3. modifications that change what the test measures
  4. accommodations that change access to the test Correct answer.

Explanation

Accommodations alter how a student accesses instruction or assessment-timing, setting, presentation, or response format-without changing the content or the standards being measured. Because the student still answers the same items on the same objectives, the supports are accommodations rather than modifications.

Question 27Component 1: Content Knowledge

After asking a higher-order question, a teacher pauses several seconds before calling on anyone. The main purpose of the pause is to

  1. keep the lesson moving at a brisk pace
  2. reduce the number of wrong answers offered
  3. ensure students are called on in order
  4. produce more responses and fuller answers Correct answer.

Explanation

Wait time of three to five seconds after a question gives students time to retrieve and organize ideas before responding. Research consistently links extended wait time to more volunteers, longer and more elaborated answers, and greater participation by students who rarely speak.

Question 28Component 1: Content Knowledge

At the end of a lesson, students write one sentence answering a question, and the teacher uses those responses to plan the next day's instruction. This is an example of

  1. a summative assessment of mastery
  2. a formative assessment used to adjust teaching Correct answer.
  3. a diagnostic assessment given before instruction
  4. a norm-referenced measure

Explanation

Formative assessment is any evidence gathered during learning that is used to adjust instruction while it can still make a difference. Because the exit responses shape the next lesson, the task functions formatively regardless of its format.

Question 29Component 1: Content Knowledge

A mathematics teacher has students build a problem with base-ten blocks, then draw a diagram of it, then solve it with numerals. This sequence reflects

  1. peer tutoring in mixed-ability pairs with a checklist
  2. the concrete-to-representational-to-abstract sequence Correct answer.
  3. an open-ended problem-based learning cycle
  4. repeated drill and practice with corrective feedback

Explanation

The concrete-representational-abstract sequence moves from manipulative modeling, to visual or drawn models, to symbolic notation. Linking each representation explicitly helps students build meaning for procedures rather than memorizing steps.

Question 30Component 1: Content Knowledge

In a kindergarten lesson, children clap once for each sound they hear in the spoken word "fish." This activity develops

  1. vocabulary breadth
  2. reading fluency
  3. phonemic awareness Correct answer.
  4. phonics knowledge

Explanation

Phonemic awareness is the ability to notice and manipulate individual sounds in spoken words, without reference to print. Segmenting a spoken word into sounds is a phonemic awareness task; phonics would involve matching those sounds to letters.

Question 31Component 1: Content Knowledge

A parent asks to see their child's cumulative file. Under the federal education privacy law governing these records, the school must

  1. let the parent inspect the records promptly Correct answer.
  2. release records only after the student turns eighteen
  3. provide copies only to a court with a subpoena
  4. refuse unless the parent files a written complaint

Explanation

The federal privacy statute gives parents (and eligible students) the right to inspect and review education records within a specified period, generally no more than 45 days after a request. Schools may not require a complaint or a subpoena as a precondition for a parent's own review.

Question 32Component 1: Content Knowledge

Which teacher comment is most likely to support a student's persistence on difficult work?

  1. You kept revising until the design worked. Correct answer.
  2. You are so talented at this subject.
  3. You got the highest score in the class.
  4. That was fast; you must be a natural.

Explanation

Feedback that names effort, strategy, and revision supports the belief that competence grows through work, which sustains persistence after setbacks. Comments that attribute success to fixed ability or to comparative rank give students little to do differently when a task becomes hard.

Question 33Component 1: Content Knowledge

In a multi-tiered system of support, Tier 1 refers to

  1. referral for special education evaluation
  2. small-group tutoring for students below benchmark
  3. intensive individual intervention for a few students
  4. core instruction and universal screening for everyone Correct answer.

Explanation

Tier 1 is the general education core: high-quality instruction and universal screening or progress monitoring provided to all students. Increasingly intensive, targeted supports are added at Tiers 2 and 3 for students who need them.

Question 34Component 1: Content Knowledge

A teacher replaces independent practice with fully worked examples for students who are new to two-step equations. This choice is most consistent with which finding?

  1. Practice should be interleaved across unrelated subject areas.
  2. Novices benefit most from studying worked examples first. Correct answer.
  3. Students learn best when problems come before any explanation.
  4. Retrieval practice only strengthens recall of isolated facts.

Explanation

For learners with little prior knowledge, studying worked examples reduces the cognitive load of searching for a solution method and frees attention for understanding the steps. As competence grows, the advantage fades and students should solve problems with less support.

Question 35Component 1: Content Knowledge

A teacher mixes volume, surface-area, and proportion problems in one homework set instead of grouping all problems of one type. This practice is intended mainly to

  1. help students select the right strategy per problem Correct answer.
  2. reduce the time students spend on homework
  3. make grading easier by spreading out items
  4. raise scores by making the work less demanding

Explanation

Interleaving forces students to identify which concept or procedure a problem requires, a discrimination skill that blocked practice conceals because every item uses the same method. The trade-off is that performance during practice may look worse while learning and transfer improve.

Question 36Component 1: Content Knowledge

A teacher gives a student a graphic organizer for essay planning, then gradually removes it as the student's drafts improve. This best illustrates

  1. differentiating the product according to student readiness
  2. using formative data to determine a final grade
  3. fading support within the zone of proximal development Correct answer.
  4. modifying grade-level standards for an individual student

Explanation

Scaffolding is temporary support that lets a learner succeed on a task just beyond independent reach, and it is withdrawn as competence develops. The gradual removal is the defining feature of fading within the zone of proximal development.

Question 37Component 1: Content Knowledge

In backward design, a teacher's first step in planning a unit is to

  1. select activities that students will find engaging and fun
  2. order the textbook chapters that will be covered
  3. choose the format of the culminating project
  4. identify desired results and evidence of learning Correct answer.

Explanation

Backward design begins with the end in mind: the understandings and skills students should retain, followed by the evidence that would show attainment. Activities and materials are chosen last so they serve the identified results rather than drive the unit.

Question 38Component 1: Content Knowledge

A student's reading score is reported at the 72nd percentile. This means the student

  1. answered 72 percent of the test items correctly
  2. earned a raw score of 72 out of 100 possible points
  3. performed at or above 72 percent of the norm group Correct answer.
  4. received a standard score of 72 on the test

Explanation

A percentile rank states the percentage of the norm group whose scores fall at or below a given score, so the student performed as well as or better than about 72 percent of the comparison sample. It is a rank, not a percentage of items correct or a raw score.

Question 39Component 1: Content Knowledge

After a unit test, a teacher finds that many students chose the same incorrect answer on one item. The most useful next step is to

  1. examine the reasoning behind the choice and reteach Correct answer.
  2. drop the item from the test and rescore
  3. assume the item was too easy and replace it
  4. award partial credit to students who chose it

Explanation

A widely shared incorrect option signals a common misconception or a flawed item rather than random error. Analyzing the reasoning behind the choice lets the teacher decide whether to reteach the concept or to revise confusing wording.

Question 40Component 1: Content Knowledge

Teaching students to notice how an author's use of sourcing and corroboration shapes a written account of an event is an example of

  1. phonological processing support
  2. disciplinary literacy in history Correct answer.
  3. generic comprehension strategy instruction
  4. test-taking skills in the content area

Explanation

Disciplinary literacy teaches the specialized ways of reading, reasoning, and communicating that experts in a field use. Sourcing and corroborating sources are history-specific practices, not general comprehension strategies that apply identically across subjects.

Question 41Component 1: Content Knowledge

Which is the best example of a language objective for an English learner in a science lesson on ecosystems?

  1. Students will appreciate the importance of biodiversity.
  2. Students will complete a worksheet on food chains.
  3. Students will understand the concept of interdependence.
  4. Students will explain food chains using sequence words. Correct answer.

Explanation

A language objective names the language functions and vocabulary students will practice and pairs them with observable academic tasks, such as explaining using sequence words. It complements rather than replaces the content objective about ecological concepts.

Question 42Component 1: Content Knowledge

A teacher regroups students for reading every few weeks based on current assessment data. This practice is best described as

  1. tracking students for the year
  2. differentiating by product
  3. cooperative learning
  4. flexible grouping Correct answer.

Explanation

Flexible grouping assigns students to temporary groups that change as their learning changes, so membership is driven by current evidence rather than fixed labels. The key feature is that regrouping is frequent and responsive.

Question 43Component 1: Content Knowledge

Before designing a behavior intervention, a team records what happens immediately before and after a student's outbursts. This process is called

  1. a functional behavior assessment Correct answer.
  2. a crisis response plan
  3. a manifestation determination review
  4. a positive behavior contract

Explanation

A functional behavior assessment identifies the antecedents, behaviors, and consequences that maintain a behavior so that intervention addresses its function. Recording what precedes and follows outbursts is the core data-collection step of that process.

Question 44Component 1: Content Knowledge

In the 5E model, students explore a phenomenon with materials before the teacher introduces the scientific explanation. This ordering is intended to

  1. shorten the time needed for direct instruction
  2. guarantee that students reach the correct answer
  3. allow the teacher to grade exploration participation
  4. surface students' ideas to anchor the explanation Correct answer.

Explanation

Exploring first gives students shared experience and reveals their prior conceptions, which the teacher then connects to formal explanation during the explain phase. This sequencing makes the eventual explanation meaningful rather than an isolated definition to memorize.

Question 45Component 1: Content Knowledge

A teacher selects a simulation because it makes a specific abstract concept visible and fits the lesson's pedagogy. This decision best reflects

  1. adding technology to meet a district requirement
  2. substituting technology for traditional tools
  3. using technology to reward finished work
  4. technological pedagogical content knowledge Correct answer.

Explanation

Technological pedagogical content knowledge is the integration of content, pedagogy, and a tool chosen because of what it uniquely affords for a particular concept. Selecting a simulation for how it reveals an abstract idea shows knowledge of all three domains at once.

Question 46Component 1: Content Knowledge

One meta-analysis reports an effect size of 0.8 for a strategy, another reports 0.2 for a different strategy. The most defensible interpretation is that

  1. the first strategy is 80 percent more effective than the second
  2. the second strategy has no practical value for teachers
  3. effect sizes from different studies cannot be compared
  4. the first strategy is associated with larger gains Correct answer.

Explanation

An effect size expresses the magnitude of a difference in standard deviation units, so 0.8 indicates a larger average effect than 0.2. Effect sizes are not percentages, and a small effect can still be educationally meaningful depending on context and cost.

Question 47Component 1: Content Knowledge

A pre-test given to a class produces scores clustered at the very top of the scale, leaving almost no room to show improvement. This is best described as

  1. a floor effect
  2. a practice effect
  3. a halo effect
  4. a ceiling effect Correct answer.

Explanation

A ceiling effect occurs when the measure is too easy or too limited for the group, so scores pile up at the maximum and cannot register growth. It makes pre-post comparisons uninformative because high scorers have no higher score to earn.

Question 48Component 1: Content Knowledge

Two teachers scoring the same set of essays disagree on several papers. The best way to improve consistency is to

  1. convert the scores to a curve
  2. add more essays to the scoring session
  3. have each teacher score only their own papers
  4. calibrate together using anchor papers Correct answer.

Explanation

Inter-rater agreement improves when scorers share a common interpretation of the criteria, usually built by scoring and discussing benchmark or anchor papers before independent scoring. Training scorers against exemplars reduces idiosyncratic standards.

Question 49Component 1: Content Knowledge

On a unit test, students answer most procedural items correctly but perform poorly on items asking them to explain their reasoning. This pattern most suggests that

  1. the procedural items were too difficult for the class
  2. students need more drill on the same procedural items
  3. instruction stressed procedures over concepts Correct answer.
  4. the explanation items should be removed from the test

Explanation

A gap between accurate execution and weak explanation indicates that students learned steps without connecting them to underlying ideas. The instructional response is to build conceptual understanding, such as through representations, explanations, and comparing examples, rather than to add more of the same practice.

Question 50Component 1: Content Knowledge

A five-item quiz turns out to have low reliability. Assuming the new items are of similar quality, the most direct way to raise reliability is to

  1. add more items on the same content Correct answer.
  2. shorten the quiz to three items
  3. raise the cut score for passing
  4. convert raw scores to percentiles

Explanation

Other things being equal, longer tests yield more stable scores because sampling error in any single item matters less to the total. Adding well-constructed items covering the same content increases reliability more directly than any change to score reporting or cut scores.
