Integrating hands-on practical and reflective feedback in teaching dental materials science to undergraduate dental students

INTRODUCTION: This study aimed to develop a module that incorporates hands-on and reflective feedback in teaching dental materials science and subsequently analyse undergraduate dental students' learning experiences with the module.

MATERIALS AND METHODS: The module was developed based on the ADDIE (Analyse, Design, Develop, Implement, Evaluate) model. First, a need analysis was conducted, followed by designing the module to address the needs. Next, the module sought experts' feedback and was piloted. The revised module was implemented among all second-year undergraduate dental students. Finally, a validated questionnaire (5-point Likert scale items and open-ended questions) was used to evaluate students' learning experiences. The questionnaire Likert scale items were analysed descriptively, whereas open-ended responses were analysed using content analysis.

RESULTS: In the analysis phase, a slight misalignment in cognitive competency levels was observed, alongside a need for the inclusion of more hands-on activities. In the design phase, learning objectives and resources were listed. Subsequently, a module consisting of four teaching sessions (3 h each) was developed, and the pilot test showed favourable feedback. The module was then implemented in small groups of 10-12 students. In the evaluation phase, 72 students (97% response rate) completed the questionnaire. The majority of students agreed with all items, with mean scores ranging from 4.53 to 4.72. Open-ended responses highlighted that hands-on activities and reflective feedback sessions were useful.

CONCLUSION: Students demonstrated positive learning experiences after participating in the module, advocating for dental educators to consider more hands-on activities and reflective feedback sessions in teaching dental materials science.
