Content relevance and content coverage in tests of grammatical ability
The Journal of Speech and Hearing Disorders
|February 1, 1986
Summary
This study found that three popular grammar tests lack sufficient content relevance and coverage. These tests may not accurately assess grammatical ability or guide effective remediation strategies.
Area of Science:
- Linguistics
- Psychometrics
- Educational Assessment
Background:
- Grammatical ability tests are crucial for educational assessment.
- Ensuring content validity is essential for accurate measurement.
- Existing grammar tests may not adequately cover the grammatical domain.
Purpose of the Study:
- To evaluate the content relevance and coverage of three widely used grammar tests.
- To develop and apply models for assessing test content orientation.
- To identify deficiencies in the content domains of these tests.
Main Methods:
- Developed a decision-making model for judging content relevance and coverage.
- Applied a comprehensive model of the grammatical domain to test items.
- Evaluated tests against external standards and internal specifications.
Main Results:
- All three tests demonstrated inadequate content relevance and coverage.
- Test content domains were deficient when compared to external standards.
- Deficiencies were also noted when tests were examined against their own content specifications.
Conclusions:
- The evaluated grammar tests exhibit significant content-related limitations.
- Inadequate content relevance and coverage can negatively impact assessment accuracy.
- These deficiencies may hinder effective language remediation efforts.
