Use of videos to teach basic science concepts in a doctor of chiropractic training program

This study examined the effectiveness of teaching biochemical concepts by video in a doctor of chiropractic training program.

Students in a biochemistry class were taught the Krebs cycle through a video exercise and glycolysis in a traditional lecture format. They received a review of both concepts and were tested. Test performance was examined. Students answered a questionnaire following the exercise.

There were no significant differences in test performance on the topic learned by the video exercise. However, students felt that both lecture and review were more effective learning tools than video.

Despite the results of other authors, our students preferred traditional didactic lecture with review rather than video. With no difference in test scores observed, the role of videos in our basic science course remains unclear, perhaps only used as an occasional supplement. These results were not expected, given the often-preferred use of technology by current learners.
