Study Notes
Principles of Test Construction and Administration
- Test is a type of assessment
- A test consists of questions administered under comparable conditions for all students
- A test is an instrument or procedure for measuring behavior
- Measurement is assigning numbers to test results based on rules
- Measurement is numerically describing the degree of a characteristic
- Tests are categorized as maximum performance or typical performance
- Maximum performance tests measure ability
- Examples include aptitude, achievement, and intelligence tests
- Typical performance tests measure behavior
- Examples include personality appraisal like interests and attitudes
- Maximum performance tests measure ability
- Measures of maximum performance
- Aptitude test: assesses natural talent or ability related to future learning and performance
- Example: Common Entrance Examinations for vocational and secondary schools
- Achievement test: assesses effects of a specific instruction or training; a measure of learning at the end of a course
- Example: end-of-term examinations, classroom tests
- Aptitude test: assesses natural talent or ability related to future learning and performance
Qualities of a Good Test
- Measures all objectives communicated to students
- Designed as an operational control for guiding experiences
- Harmonious with teacher objectives and learning sequences
- Covers all learning tasks appropriately
- Measures a representative part of each learning task
- Uses appropriate items or strategies for measuring the learning outcome
- Measurement is valid and reliable
- Reliable: provides consistent results
- Valid: measures what it purports to measure
- Clearly worded and unambiguous tests are more reliable
- Tests with more items are more reliable than those with less
- Well-planned and executed tests are more valid
- The test can be used to improve learning
Nature of Validity
- Validity refers to the adequacy and appropriateness of interpretations of assessments
- For an assessment to be valid for a specific use, the scores must be applicable
- Validity is concerned with how interpretations are made
- Validity is specific to a particular use—no assessment is valid for all purposes
- Validity is a unitary concept
- Validity involves overall evaluative judgment
- Validity requires evidence supporting the interpretations and uses of assessment results
- Major considerations in assessment validation:
- Content validation: how well tasks represent the measured domain
- Test-criterion relationship: how well performance on the assessment predicts future performance
Nature of Reliability
- Reliability refers to the consistency of measurement
- A reliable test produces consistent scores
- A highly valid test tends to give consistent results whenever it is used
- A reliable test can be invalid—for example, a physics test given to a non-physics student will be reliable but not valid
- There are different estimates for test reliability such as:
- Scoring rate/rating
- Coefficient of stability
- Coefficient of internal consistency
- Coefficient of equivalence
Methods of estimating reliability
- Scoring reliability: correlation coefficient (interscorer/inter-rater)
- Coefficient of stability: test-retest reliability
- Administering a test twice with an interval, correlating the scores
- Coefficient of equivalence: two equivalent forms given
- Administering forms of the same test to the same group
- Coefficient of internal consistency
- Kuder-Richardson formula method
- Split-half method
- Factor analysis
Usability
- Practical considerations in assessment procedures are important
- Teacher/expert training in measurement, time constraints, and logistics
Economy and Practicality
- Practicality of a test
- Ease of administration
- Time required
- Ease of interpretation and application
- Availability of equivalent forms
- Cost
Administration of Test
- Concerned with physical and psychological environment
- Three stages:
- Before the test
- During the test
- After the test
Guides to Constructing Questionnaires
- Each item should represent a hypothesis or research question
- Questions should start with the simplest ones to the most complex
- Transition between items should be smooth without jumping between ideas
- Items should be organized logically under appropriate headings
Factors affecting respondent rate
- Clarity of the questionnaire
- Length of the questionnaire
- Introduction letter including confidentiality
- Interest in the research objectives
- Incentives for respondents
