    PurposeTo determine the feasibility of implementing problem-based learning (PBL) in a large class and whether previous PBL experience is necessary.Materials And MethodsA total of 236 students from 2 large classes at China Medical University were enrolled. One class (118 students) had had a previous small-group PBL experience and another class (113 students) had not. Each class was subdivided into 15 groups (7 to 8 students/group) and took 2 separate 100-minute PBL sessions per week with the same teaching faculty. Each PBL class had 2 facilitators, 1 content expert facilitator, and 1 nonexpert facilitator. The results of the theoretical examination and case analysis examinations were analyzed using the t test. Questionnaires were used to evaluate both student and facilitator perceptions.ResultsThe feedback from both students and facilitators was positive. According to the questionnaires, both experienced and non-experienced students acknowledged that the teaching method was enjoyable and functional. The test results showed students had achieved the learning objectives. The results of the theoretical and case analysis examinations showed no significant difference between the PBL experienced class and the non-experienced class. The mean study hours spent weekly by the students after class on the course were about 6.3 +/- 1.1 hours for the non-experienced students and 4.7 +/- 0.981 hours for the experienced students (t = 11.94, P < .001). The non-experienced students showed more preference for the content expert tutor.ConclusionImplementing PBL in a large class is feasible without extracting great demand on limited educational resources. Previous PBL experience is helpful but not necessary.2010 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.
