A comparison of computer-assisted instruction and small-group teaching of cardiac auscultation to medical students.
Cardiac auscultation is suffering from declining interest, caused by competing diagnostic technology and inadequate training of doctors. Computer-assisted instruction (CAI) supporting graphics and digitized sound could be ideally suited for teaching and sharpening this skill. To evaluate this premise we randomized 35 third-year medical students to 3 hours of seminar teaching plus the use of audiotapes (group 1), the self-use of a MacIntosh-based CAI (group 2), or both (group 3). All students took a pre- and post-test consisting of eight pre-recorded cardiac events and were also assessed for computer anxiety. Although there were no significant differences between pre- and post-tests for each group and among groups, group 1 had a 4.5% deterioration in its diagnostic score compared to the 7.2% and 3.2% improvements of groups 2 and 3 respectively. Group 2 used the CAI significantly more than group 3. We conclude that CAI is at least as effective as seminars in teaching cardiac auscultation to third-year medical students.
