Study Notes
Language Assessment Principles and Classroom Practices
Reliability
- Reliability refers to the extent to which a test produces consistent scores at different administrations to a similar group of examinees.
- It is synonymous with dependability, stability, consistency, predictability, and accuracy.
- A reliable test has a high true score variance and low error score variance.
- There are four kinds of reliability:
- Student-related reliability: affected by psychological and physical factors, such as anxiety, illness, and fatigue.
- Rater reliability: includes inter-rater reliability (scorers yield inconsistent scores) and intra-rater reliability (unclear scoring criteria, bias, and carelessness).
- Test administration reliability: affected by conditions in which the test is administered, such as noise, lighting, and chairs.
- Test reliability: affected by the test's fit with time constraints, clarity of test items, and other factors.
Validity
- Validity is the degree of correspondence between the test content and the content of the material to be tested.
- A valid test measures what it is supposed to measure.
- There are five ways to establish validity:
- Content validity: the test samples the subject matter being tested.
- Criterion validity: the test performance is related to a criterion or indicator of the ability being tested.
- Construct validity: the test measures the construct it is supposed to measure.
- Consequential validity: the test has positive or negative consequences, such as impact on test takers and learners.
- Face validity: the test appears to measure the ability being tested, based on subjective judgment.
Practicality and Authenticity
- Practicality: the relationship between the resources required for the test and the resources available.
- Authenticity: the degree of correspondence between the test and real-life language use.
- Factors influencing authenticity:
- The language in the test is natural and realistic.
- Items are contextualized and reflect real-life situations.
- The test tasks are similar to normal language use.
