Explain content validity, predictive validity, and construct validity
What will be an ideal response?
Content validity refers to a test's ability to accurately sample the content taught and measure the extent to which learners understand it. It is central to achievement tests. Predictive validity is the measure of a test's ability to gauge future performance, such as the ability of the SAT and ACT to predict success in college. Construct validity is the ability to measure a learning-related characteristic that is not directly observable, such as intelligence tests' ability to measure intelligence. Intelligence is not directly observable, and it influences the amount people learn.
