Abstract:

This study empirically investigated the validity and utility of the stratified adaptive computerized testing model stradaptive developed by Weiss 1973. The model presents a tailored testing strategy based upon Binet IQ measurement theory and Lords 1972 modern test theory. Nationally normed School and College Ability Test Verbal analogy items SCAT-V were used to construct an item pool. Item difficulty and discrimination indices were rescaled to normal ogive parameters on 249 items. One hundred three freshmen volunteers at Florida State University were randomly assigned to stradaptive or conventional test groups. Both groups were tested via cathode-ray-tube CRT terminals coupled to a Control Data Corporation 6500 computer.
