A COMPARISON OF CLASSICAL AND ITEM RESPONSE THEORY PERSON/ITEM PARAMETERS OF PHYSICS ACHIEVEMENT TEST FOR TECHNICAL SCHOOLS
The study was carried out to compare classical test and item response theory based person/item parameters of technical schools’ Physics Achievement Test(PAT). The survey research design was used for the study. The population of this study comprised 1553 senior technical two (ST2) students from six technical schools in Akwa Ibom State from where a stratified random technique was used to select a sample of 1000 students. The instrument ‘Physics Achievement Test (PAT)’ was used for data collection with a reliability coefficient of 0.74 obtained using Kuder-Richardson 20 formula. BILOG MG was used to estimate the item and person parameters of classical test and item response theory, after which the item and person parameters generated from the two measurement frameworks were compared. The findings of the study showed that the two measurement frameworks produced very similar item and person statistics for the PAT. Based on these findings, it was concluded that the classical test and item response theory person and item parameters of technical school physics achievement test are comparable and can be used interchangeably.
