Study Notes

Validity

Validity measures how well a test assesses or predicts what it aims to evaluate.
A valid English speech test should include relevant items regarding figures of speech to assess knowledge accurately.

Types of Validity

Face Validity: Relates to whether the assessment appears to measure its intended aim. Often considered weak.
Content Validity: Assesses if the test content aligns with instructional objectives. Limited scope can lead to low validity.
Criterion Validity: Validates test scores against external criteria, either concurrently or predictively. Example: IQ test scores predicting performance on an achievement test.
Construct Validity: Ensures the assessment accurately measures the intended trait or ability. Adequate representation of the underlying theoretical concepts is essential.

Improving Validity of Tests

Clearly define and operationalize goals and objectives.
Align assessment measures closely with those goals and objectives.
Solicit reviews from colleagues in the same field.
Involve students in reviewing assessments for clarity and relevance.
Use comparisons with other measures or data for validation.

Reliability

Reliability indicates how consistently a test yields the same results across various conditions and scorers.
A reliable test allows a student to perform similarly on repeated attempts and across different versions of the test.

Types of Reliability

Test-Retest Reliability: Evaluates stability by administering the same test at two different times.
Equivalent/Alternate Forms Reliability: Measures equivalence by giving two different versions of a test to the same group.
Inter-Rater Reliability: Assesses agreement among multiple raters evaluating the same performance or product.
Internal Consistency Reliability: Checks consistency of item responses against overall performance metrics.

Improving Reliability of Tests

Encourage consistent performance among students by promoting best effort.
Match test difficulty to student ability levels to ensure fairness.
Establish clear and understandable scoring criteria for accurate assessment.
