Republic of the Philippines MINDANAO STATE UNIVERSITY COLLEGE OF EDUCATION Fatima, General Santos City Module 5: CHARACTERISTICS OF A GOOD TESTLesson 1: Important Thing to Remember about Validity; Types of ValidityPresented to: Dr. Ava Clare Marie O.RoblesClass Schedule: TFr /1:00-2:30 pmPresented by: Ierine Joy L. Caserial
Important Things to RememberAbout Validity Validity refers to the decisions we make, and not to the test itself or to the measurement
•not all or nothing conceptnever totallyabsent orabsolutely perfect.
What ESTIMATE does Which isValidity called do??? validity coefficient * Ranges from 0-1.
Validity can never be finally determined It is specific to each administration of the test.
Types of Validity Content Validity Criterion- related Validity Construct Validity Predictive Validity Concurrent Validity
Content ValidityA type of validation that refers to the relationship between a test and the instructional objectives
Things to remember aboutvalidity: 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.
Criterion- related ValidityCriterion- related validity is a type of validation that refers to the extent to which scores from a test relate to theoretically similar measures.
• 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.
Concurrent ValidityA 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
In Summary… Characteristics of a good testa. 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
CONTENT VALIDITY- CRITERION-RELATED CONSTRUCT-RELATED VALIDITY- VALIDITY -- refers to how well a performance on a particular set of 1. PREDICTIVE VALIDITY task can be explained by some refers to the PSYCHOLOGICAL CONSTRUCT --- involves the use of ADEQUACY and or TRAITS. criterion and a predictor. REPRESENTATIVEN Example correlating the ESS of learning results of college entrance test and student GWA at outcomes to be some future time THEORETICAL measured CONSTRUCT (predictor= CET; criterion= GWA) -- describe by determining the components of can be assure such psychological 2. CONCURRENT VALIDITY task with the use -- criterion are already of T.O.S available in which CET is correlated with some available criterion CRITICAL (predictor= GWA; criterion= CONSTRUCT 4th year high school grade) - predictors, conclusions, assumptions, inference, interpretations and relevance of evidence
