Question 1

A fellow teacher's review of test items and assessment tasks is helpful in

Accepted Answer

B

Question 2

Item discriminating power should typically not be interpreted as item validity because

Accepted Answer

Item discriminating power is often based on how well an item differentiates between high and low scorers on the same test, which is an internal criterion, rather than an external measure of validity.

Question 3

It is probably a sound motivational procedure for the teacher to announce that an upcoming test is high stakes for students.

Accepted Answer

A high-stakes test is one that has significant consequences for students, such as determining their grade or eligibility for a particular program. Announcing that an upcoming test is high stakes can motivate students to study harder and perform better on the test.

Question 4

If a test is composed of items that all have high discrimination indexes (based on the total test score), the test is said to also have

Accepted Answer

High discrimination indexes indicate that items are good at distinguishing between high and low performers, which contributes to the overall reliability of the test.

Question 5

If 8 out of 10 students in the upper group and 2 out of 10 students in the lower group answer an item correctly, then the difficulty and discriminating power of the item would be

Accepted Answer

The answer of If 8 out of 10 students in...

Question 6

Low discriminating power is acceptable, but only if the item

Accepted Answer

Low discriminating power is acceptable if the item measures a unique learning outcome, as it may assess a specific skill or knowledge area not covered by other items.

Question 7

The effect of guessing on scores can be best be reduced on a multiple-choice test by increasing which of the following?

Accepted Answer

Increasing the number of alternatives in a multiple-choice test reduces the probability of guessing the correct answer, thereby minimizing the effect of guessing on scores.

Question 8

When arranging items in a test, it is best to ensure which of the following?

Accepted Answer

Placing essay questions last allows students to manage their time better, as they can first complete objective questions that typically require less time.

Question 9

Which of the following is a major limitation of using item analysis procedures with the typical classroom test?

Accepted Answer

Item analysis procedures are less effective with a small number of students because statistical measures like item difficulty and discrimination require larger sample sizes to be reliable.

Question 10

If item analysis data showed that an item was answered correctly by 8 out of 10 students in the upper group and 6 out of 10 students in the lower group, the difficulty of the test item is

Accepted Answer

The difficulty of a test item is calculated by the proportion of students who answered it correctly. Here, 14 out of 20 students (8 from the upper group and 6 from the lower group) answered correctly, so the difficulty is 70%.

Question 11

In a 100-item criterion-referenced test, how many items should have zero difficulty at the end of instruction?

Accepted Answer

In a criterion-referenced test, items should not have zero difficulty, as they are designed to measure whether students have achieved specific learning objectives. Zero difficulty would imply that the item is too easy and does not effectively assess mastery of the content.

Question 12

Which of the following is a desirable procedure for reducing student cheating on a test?

Accepted Answer

Having students turn in all scratch paper is a desirable procedure for reducing student cheating on a test because it eliminates the opportunity for students to use unauthorized materials during the test.

Question 13

A multiple-choice test contains 100 items, each having a correct answer and three distracters.Which of the following would be the corrected score for 70 correct and 24 incorrect on the test using the correction-for-guessing formula?

Accepted Answer

The correction-for-guessing formula is: Corrected Score = Number of Correct Answers - (Number of Incorrect Answers / (Number of Choices - 1)). Here, it is 70 - (24 / 3) = 70 - 8 = 62.

Question 14

A distracter in a multiple-choice item is judged good if it attracts more students who have

Accepted Answer

A good distracter is one that attracts students who have obtained low scores, indicating that it effectively differentiates between those who understand the material and those who do not.

Question 15

A test item has positive discriminating power when answered correctly by

Accepted Answer

More high-scoring students answering a test item correctly indicates that the item is able to differentiate between high and low-scoring students, which is a desirable property for a test item.

Question 16

If test directions instruct students to "answer every item," it is not recommended that educators

Accepted Answer

Correcting for guessing is not recommended when students are instructed to answer every item, as it assumes that some items are left unanswered due to uncertainty.

Question 17

On a test of 50 students, if 25 students answered an item correctly, the item difficulty is

Accepted Answer

Item difficulty is calculated as the percentage of students who answered the item correctly. If 25 out of 50 students answered correctly, the item difficulty is 50%.

Question 18

An item analysis yields the following results for a multiple-choice item (alternative A is the correct answer): Number of students in the upper and lower scoring groups on the total test choosing each alternative.
Alternative A* B C D Omit Total
Upper Group 3 1 5 1 0 10
Lower Group 6 2 0 1 1 10
Which one of the following statements is NOT justified by these results?

Accepted Answer

The answer of An item analysis yields the following results...

Question 19

The 10 students with the highest scores on a set of 8 assessment tasks had the following distribution of scores on one of the assessment tasks that was scored on a 3-point scale: 1 (1 student), 2 (5 students), 3 (4 students).Which of the following distributions of scores for the 10 lowest scoring students indicates that the task discriminated negatively?

Accepted Answer

A negatively discriminating task means that lower scoring students perform better than higher scoring students. In option D, the lowest scoring students have more high scores (3s) than the highest scoring students, indicating negative discrimination.

Question 20

The correction-for-guessing formula assumes that student guesses are based on which of the following?

Accepted Answer

The correction-for-guessing formula assumes that student guesses are based on blind choosing, meaning they have no information to guide their choice.
