Question 1

A standard deviation is a measure of

Accepted Answer

Standard deviation is a measure of the spread of scores around the mean. Option A refers to the test objectives, Option B refers to the range, and Option D refers to the test validity, which are not related to standard deviation.

Question 4

Teachers who hold lower expectations for ethnic minority students may also be negatively influencing the students' testing performance and assessment experiences.

Accepted Answer

Research has shown that teachers' expectations for their students play a significant role in student achievement. When teachers hold lower expectations for ethnic minority students, these students may internalize and fulfill those expectations, leading to poorer academic performance and less favorable assessment experiences. On the other hand, when teachers hold high expectations for all students regardless of ethnicity, it can lead to better outcomes for all students.

Question 6

Criterion-referenced grading systems use standards of subject mastery and learning to determine grades.

Accepted Answer

Criterion-referenced grading systems are based on specific learning objectives and standards, with grades being determined by how well a student has mastered those objectives.

Question 7

Using any grading system requires the teacher to be able to defend the grades assigned to students.

Accepted Answer

This is because the teacher needs to have a clear and objective criteria for grading students, and be able to explain to students and their parents how their grades were determined.

Question 8

Using authentic assessments does not guarantee reliability and validity.

Accepted Answer

While using authentic assessments may increase the alignment between assessment tasks and real-world skills or situations, reliability and validity still depend on many factors, such as the consistency of scoring and the effectiveness of the assessment design. Therefore, using authentic assessments alone does not ensure reliable and valid results.

Question 10

Performance standards are criteria that specify the expected quality or level of student learning.

Accepted Answer

Performance standards set clear expectations for what students should know and be able to do at different stages of their education. They define the level of knowledge, skills, and abilities that students are expected to demonstrate in order to meet academic goals and succeed in their future careers. By setting clear standards, educators can focus on developing effective instruction and assessment strategies that help students meet these expectations.

Question 11

What is the median for the following set of scores? Scores: 66,66,74,96,98

Accepted Answer

The median is the middle score when the scores are arranged in order. Arranging the scores in ascending order gives: 66, 66, 74, 96, 98. The middle score is 74, which is the median.

Question 12

The relationship between the standard deviation and test scores is that the larger the standard deviation,the

Accepted Answer

Standard deviation measures how spread out the scores are in a distribution. So, a larger standard deviation indicates greater variability in the distribution, meaning that the scores are more spread out from the mean.

Question 13

Approximately what percentage of the scores in a normal distribution is higher than one standard deviation above the mean?

Accepted Answer

In a normal distribution, approximately 68% of the scores fall within one standard deviation above and below the mean, leaving 32% of scores outside of that range. Since the distribution is symmetrical, half of the 32% is above one standard deviation above the mean, which is roughly 16%. Therefore, the answer is B.

Question 14

The Algebra I class mean and standard deviation are 80 and 10,respectively.The Biology II class mean and standard deviation are 79 and 4,respectively.Kristen scored 90 in Algebra I and 87 in Biology II.The most valid conclusion to be drawn from these data is that Kristen

Accepted Answer

Kristen's z-score in Algebra I is (90-80)/10 = 1, while in Biology II it is (87-79)/4 = 2. This means she scored better relative to her class in Biology II.

Question 15

Rob scored exactly in the middle of his class on the social studies exam.A valid interpretation of Rob's performance is that he scored exactly at the

Accepted Answer

If Rob scored exactly in the middle of his class, it means that half of the class scored below him and half of the class scored above him. This is the definition of the median in a symmetrical frequency distribution. The mean and mode may not necessarily be in the middle of the distribution, so they cannot be valid interpretations of Rob's performance in this context.

Question 16

Woolfolk recommends that teachers have communications with students' family members that are not tied to a grade.

Accepted Answer

Woolfolk suggests that teachers should have regular communication with families that is not solely dependent on grades or academic performance. This can help to build positive relationships and provide support for students beyond their academic needs.

Question 17

Authentic assessments are procedures that directly assess student performances in "real-life" situations.

Accepted Answer

Authentic assessments are designed to evaluate a student's skills and knowledge in real-life contexts or scenarios. This type of assessment emphasizes application and problem-solving skills rather than rote memorization of facts. Examples of authentic assessments include performance tasks, simulations, case studies, and projects.

Question 18
