Comparison between Virtual and Traditional Learning Methods for Orthodontic Knowledge and Skills in Dental Students: A Quasi-Experimental Study

A gradual transition from traditional face-to-face learning to online learning has been observed globally following the COVID-19 pandemic. The aim of the study was to compare online and traditional learning methods in relation to orthodontic knowledge and skills acquired in undergraduate courses. A quasi-experimental design was used with two consecutive year classes of 198 dental students at Jazan University, Saudi Arabia. The experimental (virtual) group of 92 students received the content of a clinical orthodontic course virtually using the Blackboard Collaborate (TM) platform. The control (traditional) group consisted of a previous cohort of 106 students who enrolled in the same course but received traditional classroom education. The students were evaluated through a semester, and both groups obtained the same content and exam questions. The students in the virtual group scored higher in the final theory exam than the traditional group (p-value < 0.05). However, no significant difference in the overall orthodontic knowledge and skills was observed between the groups at the end of the course. Both learning methods showed moderate positive correlation between orthodontic knowledge and skills. In conclusion, virtual learning can serve as an effective alternative to traditional face-to-face learning for teaching orthodontic knowledge and skills to the dental students.
