METHODS TO ESTABLISH VALIDITY AND RELIABILITY

Content Validity Evidence- established by inspecting a test question to see whether they correspond to what the user decides should be covered by the test.

Makes and measures objectives

Criterion-Related Validity Evidence- measures the legitimacy of a new test with that of an old test. Less expensive, shorter and can be administered to groups.

Makes sure a new test is reliable

Test - Retest or Stability- test is given twice and the correlation between the first set of scores and the second set is determined

Can determine if and how much data a student memorizes on a test.

Construct Validity Evidence- tells whether the results from a test correspond to what you would expect (based on your own knowledge about what is being measured) tells something about the construct validity for a test.

Predicts subsequent performance, success or failure in the next grade.

Alternate Forms or Equivalence- administers two forms of a equivalent test to a group of students, and the correlation b/w the two sets of scores is determined.

Eliminates the problems of memorizing material on the test.

Internal Consistency- designed to measure a single basic concept. Only interested in what the student knows about specific subject matter.

Can prove if students have or have not mastered a particular subject.
