Objectives: The content of biomedical sciences, especially biochemistry and molecular biology, is complex and abstract. Teachers commonly add illustrations to aid interpretation and understanding. As technologies advance, animated videos are created to visualize the complex concepts in life sciences. However, the actual impact of watching those videos on dental education remains unclear. The goal of this study was to examine the effectiveness of the whiteboard animated videos for learning biochemistry. Methods: A retrospective study was conducted with 143 first-year DDS students enrolled in the Biochemistry and Nutrition course at the University of the Pacific, Arthur A. Dugoni School of Dentistry during the 2019-2020 academic year. Twenty-five videos related to the course content, including 16 required and 9 recommended videos, were assigned for students to watch. The association between video watching and students’ course grades was analyzed with Pearson correlation. Results: One outlier of students’ video-watching number was excluded after the generalized ESD test. Regression analysis showed that students’ video-watching numbers were positively correlated with their course grades (P=0.02, r=0.03-0.35(95%CI)). Approximate 4% of students’ course grade was contributed by watching the videos (R square=0.038). Conclusion: This study is the first in dental education to examine the value of whiteboard animated videos in teaching biochemistry. Although video watching contributes to a small portion of students’ course performance, these results are promising and support that whiteboard animated videos might facilitate learning in biomedical sciences.
