Validity and Reliability Importance to Assessment and Learning

1. Test-retest Reliability

1.1. Test is given twice and the correlation of the two score is recorded

1.1.1. importance to assessment and learning because it tells us if the scores from the first test are reliable

2. Alternate Form Reliability Equivalent

2.1. used to estimate the two score reliability on a test

2.1.1. importance to assessment and learning because it eliminates the problem of memory and practice involved in test-retest

3. Internal Consistency

3.1. items should be correlated with each other and the test consistent

3.1.1. importance to assessment and learning because it estimates reliability

4. Predictive validity evidence

4.1. importance to assessment and learning provides a strong argument for the worth or a test, even if it seems questionable on other grounds

4.1.1. Session Rule 1

4.1.2. Session Rule 2

4.2. refers to how well the test predicts some future behavior of the test takers

5. Concurrent Cirterion-related validity

5.1. deals with measures that can be administered at the same time as the measure to be validated

6. Content Validity

6.1. simplest form of validity

6.2. established by inspecting test question to see whether they correrspond to what the user decieds should be coved on the test

6.3. importance to assessment and learning because it answers the question does the test measure the instructional objectives.

7. Construct Validity evidence

7.1. if a the relationship to other information correspond well with some theory

7.2. importance to assessment and learning because it lets you know if the results of the test are what you expected
