The objectives for this study were to: (1) develop a valid, reliable measure of test-wiseness with equivalent forms for use with students in the health sciences; and (2) determine the level of test-wiseness of entering medical students. The test-wiseness areas included in this study were: similar options, umbrella term, item give-away, convergence principle, length of correct option, and stem-option cue. The content for the test items was based on obscure, factual medical information taken from "Dorland's Illustrated Medical Dictionary." Each of the two test forms contained 24 four-choice multiple-choice items. The test, entitled Measure of Obscure Medical Information, was administered to 15 students enrolled in a workshop on test-taking skills and 39 other entering medical students. Although the test is still in the early stages of development, there is some evidence of both internal consistency and alternate form reliability. Some degree of validity for measuring test-wiseness is indicated by the significant gain made on the test by students instructed in test-taking skills. The test seems appropriate for use with health science students because of the nature of the content and the level of performance on the test by medical students. (BW)
