Properties of Assessment Methods Flashcards
Properties of Assessment Methods (Enumerate)
- Validity
- Reliability
- Fairness
- Positive Consequences
- Practicality and Efficiency
- Ethics
Something valid is something fair
A valid test is one that measures what it is supposed to measure
appropriateness, correctness, meaningfulness, and usefulness of the specific conclusions that a teacher reaches regarding the teaching-learning situation
Validity
Types of Validity
- Face
- Construct
- Content
- Criterion-related
content and format of the instrument
i. Students’ adequate experience
ii. Coverage of sufficient material
iii. Reflect the degree of emphasis
Content Validity
outward appearance of the test, the lowest form of test validity
Face Validity
the student is judged against a specific criterion
Criterion-related Validity
the test is loaded on a construct or factor
Construct Validity
Something reliable is something that works well and that you can trust
A reliable test is a consistent measure of what it is supposed to measure
Is the extent to which an experiment, test, or any measuring procedure yields the same result on repeated trials
Reliability
is the extent to which two items measure identical concepts at an identical level of difficulty.
is determined by relating two sets of test scores to one another to highlight the degree of relationship or association
Equivalency Reliability
sometimes called test, re-test reliability
is the agreement of measuring instruments over time
to determine stability, a measure or test is repeated on the same subjects at a future date
Stability Reliability
is the extent to which tests or procedures assess the same characteristic, skill, or quality.
It is a measure of the precision between the observers or of a the measuring instruments used in a study
Internal Consistency
Is the extent to which two or more individuals (coders or raters) agree.
addresses the consistency of the implementation of a rating system
Interrater Reliability
Calculated using the
i. Spearman-Brown prophecy formula
ii. Kuder-Richardson - KR 20 and KR 21
Split-Half Method
Consistency of test results when the same test is administered at two different time periods
i. Test-Retest Method
The Concept that assessment should be “fair” covers a number of aspects.
- Student Knowledge and Learning Targets of Assessment
- Opportunity to Learn
- Pre-Requisite Knowledge and Skills
- Avoiding teacher stereostype
- Avoiding bias in assessment tasks and procedures
