Abstract

Objective: This article aimed to compare the education effectiveness of online/offline PBL teaching methods and provide new ideas for the improvement of PBL teaching mode in dental education. Methods: In the periodontology course, 124 stomatology students in the 2017 and 2018 grades at the College of Stomatology at Jinan University were randomly divided into two groups: online PBL teaching group and offline face-to-face PBL teaching group. The teacher issued the same cases and questions to the two groups of students and asked students to discuss problems in small groups, retrieve literature and solve problems. PowerPoint reports and defense were also needed. After the course, a questionnaire survey was adopted to evaluate the application effect of online and offline PBL teaching modes, and the results were analyzed through SPSS software.Results: Both groups of students were able to master their knowledge and improve their abilities well. However, Compared with the offline PBL teaching group, students in the online PBL teaching group showed higher satisfaction and better improvement of their literature retrieval ability and teamwork skills.Conclusion: Compared with the offline PBL teaching mode, the online PBL teaching method is a more effective teaching method to gain students recognition and help dental students develop their literature retrieval ability and teamwork skills and to gain student recognition.
