INTRODUCTION: Teaching methods like blackboard teaching and using PowerPoint (PPT) presentations have been used in many medical colleges, but the impact and studentsâ€™ preference of these aids over one another have not been proved. The aim of this study was to know the second-year Bachelor of Medicine and Bachelor of Surgery (MBBS) studentsâ€™ preferred teaching method, such as blackboard or PPT presentation in forensic medicine. MATERIALS AND METHODS: A cross-sectional study was conducted in the Department of Forensic Medicine. A total of 150 second-year MBBS students were divided into two groups randomly. Each student was asked to assess the impact of lectures given by two different lecture delivery methods by filling in a questionnaire. After lectures we compared the effect of lectures delivered by different methods with an objective test. The data were analyzed by Studentâ€™s t-test. RESULTS: We found that PPT presentations had made a positive impact on various aspects of their learning in forensic medicine than blackboard method. We conclude that use of this audiovisual aid is very useful than conventional blackboard teaching in forensic medicine. CONCLUSION: This study has proved that teaching using PPT presentations is an effective teaching method when compared with conventional blackboard teaching.
