Module 5: CHARACTERISTICS OF A GOOD TESTLesson 1: Important Thing to Remember about
Validity; Types of Validity
To be able to know and remember the importance of validity
To be able to know the types of validity and to apply correctly its purpose
To understand the difference between the types of validity by means of their
variables
Objectives:
Validityrefers to the
decisions we make, and not
to the test itself or to the measurement
Important Things to Remember About Validity
•not all or nothing concept
never totally absent or absolutely perfect.
What does
Validity
do???
ESTIMATE Which
is called
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
Concurrent Validity
Construct Validity
Predictive Validity
Content Validity
A type of validation that refers to the relationship between a test and the instructional objectives
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:
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.
Construct
Validity
• a type of validation that refers to a measure of the extent to which a test measures a hypothetical and unobservable variable or quality
Predictive
Validity
•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 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
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-
refers to the ADEQUACY and REPRESENTATIVENESS of learning outcomes to be
measured
can be assure with the use of T.O.S
