MODELS OF EVALUATION AND THEIR RELATION TO STUDENT CHARACTERISTICS

The union and disjunction models for combining individual test marks to yield final grade distributions were outlined. It was expected that these models would differentially favor students according to their characteristic methods of learning and studying. The models were examined empirically in two educational psychology classes; five performance assessments were available, as well as eleven dimensions of study behavior and academic attitudes. While there was a substantial correlation between the distributions derived from the two models, they were found significantly to favor different student characteristics. The union model, relative to the disjunction model, favored students who were dependent, who interrelated different aspects of their course work, who scheduled their work and who rote-learned material. These differences were interpreted in terms of the educational assumptions underlying the two models. Some implications of the study for grading practice were suggested.
