A
A teacher is creating a classroom assessment for her students, and wants to consider both validity and reliability of the assessment. This one is more important to consider.
What is evidence of validity?
An assessment is highly consistent, measures the intended grade-level standards, and supports accurate instructional decisions. This assessment is providing evidence of these concepts.
What are validity and reliability?
A student's score changes dramatically each time they take the same assessment, even though no additional teaching on that topic occurred. The assessment lacks this characteristic.
What is reliability?
When teachers include class participation as part of a math test grade, they are missing this evidence.
What is validity?
When seeking evidence of validity, accuracy refers to whether a test measures this.
What is the test supposed to measure?
A teacher reviews math word problems and determines that the reading level of the problems is several grade levels above the grade she is assessing. This type of evidence is missing from the assessment.
What is validity?
A teacher wants to give one test to her first period class and a different test to her second period class. She needs to be concerned about this type of reliability.
What is alternate-form reliability?
According to Popham, this word is a synonym for reliability.
What is consistency?
In gathering evidence of validity, grade level teachers are evaluating whether an assessment is appropriate for the decisions it is intended to support. This is an example of this type of validity evidence.
What is fitness for purpose?
A teacher sent home benchmark assessment results. A parent called to ask about the range of scores above and below their child’s score. This is the term for what they were asking about.
What is the Standard Error of Measure?
A teacher gives students the same reading assessment two weeks in a row to determine whether the results remain stable. The teacher is gathering this type of reliability evidence.
What is test-retest evidence of reliability?
This refers to a teacher analyzing a student's overt answer on an assessment and drawing a conclusion about what the student knows about the topic.
What is a score based interpretation?
Internal Test Reliability measures the consistency among test items. In this scenario, teachers would not want a test to have a high Internal Test Reliability.
What is a test that is assessing multiple different skills?
A teacher told her students that everyone who passes the math test would get extra recess on Friday. After giving two versions of the test, only 5% of the students had a different outcome between the two assessments, meaning this was 95%.
What is the Decision-Consistency Index?
Students get a list of spelling words from their teacher and class time to practice the words in class, so most students consistently make 100s. This test is not valid for assessing spelling because it is doing this.
What is assessing memorization?
This statistical value could change significantly for test-retest reliability if a teacher waits a long time between test administrations or reteaches the unit before the 2nd administration.
What is the correlation coefficient?
