Introduction: As the value of interactive teaching becomes increasingly recognized, the Flipped Classroom model is receiving more attention in the medical education community. In this model, learners master core declarative knowledge through self-learning prior to class and then expand upon this learning with integrative class exercises. The objective of this study was to assess the effectiveness of the new Flipped Classroom in a Canadian Emergency Medicine postgraduate program. Methods: The residents and staff were educated on the new model. An online questionnaire was sent to all EM residents and staff who had participated in the program 9 months after implementation. The survey tool assessed the participants opinions on utility, time-management, effectiveness in learning material, sustainability, collaboration with other members and overall impressions. Resident scores on national preparatory examinations including the Canadian In-Training Examination (CITE) and the American Board of Emergency medicine (ABEM) were compared before and after implementation of the new model. Results: Teaching staff were trained in the Flipped Classroom model and the majority of teaching sessions for the 2016 academic year were carried out using this paradigm. In addition, third year postgraduates received intensive training in the theory and implementation of interactive teaching techniques. A curriculum renewal committee generated objectives for each teaching session and suggested materials for learner pre-reading. Conclusion: Overall, both residents and staff physicians indicated that the flipped classroom model is a better format for EM academic day learning. Residents and staff collaborated more and felt more engaged during academic day. Residents spent more time preparing for the sessions with the new model, while staff spent less time preparing. Paired comparisons of same residency years for test exam scores using Wilcoxon signed-rank test showed an improvement in both CITE and ABEM exam test scores. In conclusion, the new flipped classroom model produced improvements in educational experience, satisfaction, and test examination scores.
