GENERALIZABILITY, VALIDITY, AND EXAMINEE PERCEPTIONS OF A COMPUTER-DELIVERED FORMULATING-HYPOTHESES TEST

The Formulating-Hypotheses (F-H) item presents a situation and asks examinees to generate as many explanations for it as possible. This study examined the generalizability, validity, and examinee perceptions of a computer-delivered version of the task. Eight F-H questions were administered to 192 graduate students. Half of the items restricted examinees to 7 words per explanation, and half allowed up to 15 words. Generalizability results showed high interrater agreement, with tests of between 2 and 4 items scored by one judge achieving coefficients in the .80s. Construct validity analyses found that F-H was only marginally related to the GRE General Test, and more strongly related than the General Test to a measure of ideational fluency. Different response limits tapped somewhat different abilities, with the 15-word constraint appearing more useful for graduate assessment. These items added significantly to conventional measures in explaining school performance and creative expression.
