The benefits of incorporating active learning into online, asynchronous coursework in dental physiology

The COVID-19 pandemic required a shift to online learning that posed particular challenges for the education of dental students. Basic science courses were presented in an online, asynchronous format to facilitate small group rotations through preclinical work. The success of active learning was previously examined in a Dental Physiology course, and it was desired to reassess those methods in an online environment. Students were provided with prerecorded lectures containing learning activities, and the effectiveness was compared with traditional lecture recordings. On surveys, dental students had more positive perceptions of online recordings that incorporated active learning strategies, with higher perceived effectiveness of the lecturer, ability to pay attention, motivation to study, and confidence with the material. This was similar to the previous study, in which face-2-face (F2F) active learning was more positively reviewed than traditional lectures. Compared with these past sections, the online cohort expressed similarly positive perceptions of the active learning sections, but the online traditional lectures were perceived to be less effective than F2F lectures. Despite the differences in student perceptions, unit exam scores were similar for didactic lectures in both online and F2F settings. Unit exam scores were significantly higher when active learning strategies were employed, with the highest performance levels in the F2F cohort. While active learning strategies continue to be effective, further research is needed to optimize these methods and engage students in online coursework. The results suggest the importance of active and collaborative learning opportunities in the education of students in physiology coursework.
