Abstract
The construction and evaluation of a computerised concept attainment test. The principal objectives of the study were the computerisation of the Concept Attainment Test of Schepers (1971), and the determination of its reliability and validity. The computerised concept attainment test (CAT) was applied to 185 undergraduates in Informatics and
Computer Science. For comparative purposes the original CAT was applied to 205 first-year students in Mathematics. For validation purposes the semester marks and examination marks of Informatics II and III, and of Computer Science II and III, were used. For Informatics II all the scores of the CAT correlated negatively with the second semester marks. None of the correlations with examination marks were statistically significant. No statistically
significant correlations were obtained in respect of Informatics III. For Computer Science II “number correct” (Form
A) correlated with all the semester and examination marks. No significant correlations were obtained in respect of
Computer Science III.
