{"title":"Dental Students\u2019 Attitude towards Problem-Based Learning before and after Implementing 3D Electronic Dental Models","authors":"Hai Ming Wong, Kuen Wai Ma, Lavender Yu Xin Yang, Yanqi Yang","volume":1244,"journal":"International Journal of Educational and Pedagogical Sciences","pagesStart":1,"pagesEnd":7,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/10007281","abstract":"<p>Objectives: In recent years, the Faculty of Dentistry of the University of Hong Kong have extended the implementation of 3D electronic models (e-models) into problem-based learning (PBL) of the Bachelor of Dental Surgery (BDS) curriculum, aiming at mutual enhancement of PBL teaching quality and the students&rsquo; skills in using e-models. This study focuses on the effectiveness of e-models serving as a tool to enhance the students&rsquo; skills and competences in PBL. Methods: The questionnaire surveys are conducted to measure 50 fourth-year BDS students&rsquo; attitude change between beginning and end of blended PBL tutorials. The response rate of this survey is 100%. Results: The results of this study show the students&rsquo; agreement on enhancement of their learning experience after e-model implementation and their expectation to have more blended PBL courses in the future. The potential of e-models in cultivating students&rsquo; self-learning skills reduces their dependence on others, while improving their communication skills to argue about pros and cons of different treatment options. The students&rsquo; independent thinking ability and problem solving skills are promoted by e-model implementation, resulting in better decision making in treatment planning. Conclusion: It is important for future dental education curriculum planning to cope with the students&rsquo; needs, and offer support in the form of software, hardware and facilitators&rsquo; assistance for better e-model implementation.<\/p>\r\n","references":"[1]\tJoffe, L., OrthoCAD: digital models for a digital era.
