Effects of Immediate Knowledge of Results on Achievement Test Performance and Test Dimensionality. Research Report 80-1.
Gialluca, Kathleen A.; Weiss, David J.
Two studies investigated the effects of immediate knowledge of results (feedback) of college biology test items upon performance on subsequent items. Students received correct answers after responding to each item. Tests and correct answers were administered on a cathode-ray terminal connected to a computer. Feedback did not systematically increase total test scores, as would be expected if students were using results from previously administered items as clues for subsequent items. Furthermore, feedback did not alter the latent trait and item characteristic curve assumption of unidimensionality, or local independence, among achievement test items. (CP)
