“Cardiac Cycle: The First Step, ” which discretely, non-ambiguously, and accurately presents basic essential information on the cardiac cycle, was compared with conventional material in terms of educational efficiency. Twenty-six first-year medical students were randomly assigned to either material. The conventional group was presented with a standard textbook with a typical figure and text. The students were blinded as to the origin of the materials. After self-study, the same quiz (30 two-item choice questions asking basic essential information) was given to both groups and was scored by a blinded rater. The number of correct answers was 25.7±3.7 (mean±SD) in the conventional group and 29.4±1.1 in the ‘first-step group’(p<0.01).
