Validity and Reliability

1. Important to learning and assessment because teachers can learn about academic levels and more efficient tests

2. This includes making sure tests are used for specific outcomes and purposes

3. Tests can have a variety of purposes and should be used accordingly

4. Types of Validity Evidence

5. Content

6. Criterion-related

7. Consists of using simple questions to assess student’s area of learning.

8. Involves how scores are correlated with each other and consists of two types

9. Concurrent relates to measurements validity of scores at the same time

10. Predictive relates to predicting students performances over a specific period

11. Validity

12. This validity is theory related, which involves how it is related to other factors information

13. Construct

14. Consists of two ways to measure children’s abilities using one or a combination of traits

15. Internal Consistency

16. Reliability

16.1. Tests reliability is another important part in how tests are evaluated.

16.2. Important to learning and assessment because teachers can learn about academic levels and more efficient tests

16.3. This involves the consistency level of students who are administered the test over a period.

17. Test-Retest or Stability

18. Alternate Forms or Equivalence

19. Taking the test more than once to obtain an estimation score

20. This includes giving students different forms of test to determine correlation scores.

21. Split-half or odd-even means the test is split for determining correlation consistencies

22. Kuder-Richardson tests for common factors

23. Types of Reliability Methods
