Validity and Reliability создатель Mind Map: Validity and Reliability

1. Validity and reliability are important in learning and assessment. They can help determine if a test's outcomes align with their objectives, and can determine if a test will have similar results each time it is taken.

2. Content Validity Evidence

2.1. Does the test measure the instructional objectives?

2.1.1. Personality Tests

2.1.1.1. Do these test results accurately describe the test taker?

2.1.2. Standardized Tests

2.1.2.1. Do these tests accurately display learner achievement throughout the school year?

2.1.2.1.1. Can improve instruction methods in order to meet achievement standards

3. Internal Consistency

3.1. Split-half methods

3.1.1. Allows educators to determine if learners perform consistently throughout an assessment.

3.2. Kuder-Richardson methods

3.2.1. Can measure a single concept

4. Criterion Related Validity Evidence

4.1. Concurrent Criterion-Related Validity Evidence

4.1.1. IQ Tests

4.1.1.1. Numeric value. Does this test accurately measure a learner's IQ?

4.1.1.1.1. Can provide information about progress in a numerical value

4.2. Predictive Validity Evidence

4.2.1. If learners are high achievers in high school, will they be high achievers in college?

4.2.1.1. Can help improve instruction and tailor individual instruction

5. Test-Retest/Stability

5.1. Involves memory and experience. These can effect outcomes of test-retest reliability.

5.1.1. Can provide information to educators on how to prepare their learners for tests (mental readiness)

5.2. Are tests reliable if they yield similar results across time?

5.2.1. Can help provide information for norm-referenced tests

6. Alternate Forms/Equiavlence

6.1. Can eliminate problems from test-retest methods

6.1.1. Can eliminate problems of memory. Helps teachers use alternate methods to prepare their learners
