ABSTRACT
PURPOSE:
To compare, using a prospective, randomized controlled study, three methods of teaching a medical school parasitology course computer-based instruction, traditional lecture-based instruction, and a combination of computer-based and lecture-based instruction.METHOD:
A single class of the University of Utah School of Medicine was randomized into three study groups for the second-year parasitology course. The computer group (n = 29) used a locally developed interactive parasitology computer program; the lecture group (n = 32) had traditional lectures, and the combined group (n = 33) used both the computer program and lectures. Students' knowledge was assessed using a pretest, a final examination, and a posttest administered four months after the course. Students also used logs to track the amounts of time they spent studying. Their impressions and course evaluations were collected using a standardized course-evaluation form.RESULTS:
The groups' scores on the pretest, final examination, and posttest were not statistically significantly different. Students in the computer group averaged 26.8 hours of studying over the two-week course compared with 32.1 hours in the lecture group and 32.7 hours in the combined group. The difference in study times between the computer and combined groups yielded a significant p value of 0.036. Students were generally positive about the course and the computer program.CONCLUSION:
Students can learn parasitology from computer-based instruction as effectively as from traditional lecture-based instruction, and they can do so in less time.
