Caserial Republic of the Philippines MINDANAO STATE UNIVERSITY COLLEGE OF EDUCATION Fatima, General Santos City Module 5: CHARACTERISTICS OF A GOOD TEST Lesson 1: Important Thing to Remember about Validity; Types of Validity
2
Objectives:
3
Validity refers to the decisions we make, and not to the test itself or to the measurement Important Things to Remember About Validity
4
not all or nothing concept never totally absent or absolutely perfect.
5
What does Validity do??? ESTIMATE Which is called validity coefficient * Ranges from 0-1.
6
Validity can never be finally determined It is specific to each administration of the test.
7
Types of Validity Content Validity Criterion- related Validity Concurrent Validity Construct Validity Predictive Validity
8
Content Validity A type of validation that refers to the relationship between a test and the instructional objectives
10
The evidence of the content validity of your test is found in the Table of Specification. This is the most important type of validity to you, as a classroom teacher. There is no coefficient for content validity. It is determined judgmentally, not empirically. Things to remember about validity:
11
Criterion- related Validity Criterion- related validity is a type of validation that refers to the extent to which scores from a test relate to theoretically similar measures.
12
a type of validation that refers to a measure of the extent to which a test measures a hypothetical and unobservable variable or quality refers to a measure of the extent to which a person’s current test results can be used to estimate accurately what that person’s performance or other criterion, such as test scores will be at the later time.
13
Concurrent Validity A type of validation that requires the correlation of the predicator or the concurrent measure with the criterion measure. The higher the validity coefficient, the better the validity evidence of the test
14
In Summary… Characteristics of a good test a. Valid -----refers to the extent to which measure what is purpose to measure. b. State that if the test item is congruent to the behavior to be tested it is then valid. Types of Evidence
15
CONTENT VALIDITY- refers to the ADEQUACY and REPRESENTATIVEN ESS of learning outcomes to be measured can be assure with the use of T.O.S CRITERION-RELATED VALIDITY- 1. PREDICTIVE VALIDITY --- involves the use of criterion and a predictor. Example correlating the results of college entrance test and student GWA at some future time (predictor= CET; criterion= GWA) 2. CONCURRENT VALIDITY -- criterion are already available in which CET is correlated with some available criterion (predictor= GWA; criterion= 4 th year high school grade) CONSTRUCT-RELATED VALIDITY -- refers to how well a performance on a particular set of task can be explained by some PSYCHOLOGICAL CONSTRUCT or TRAITS. THEORETICAL CONSTRUCT -- describe by determining the components of such psychological task CRITICAL CONSTRUCT - predictors, conclusions, assumptions, inference, interpretations and relevance of evidence
