Background: Traditional didactic lecture is more passive in nature and less effective as a teaching tool compared with active learning methods, such as problem-based learning. However, a well-organized lecture remains one of the most effective ways to integrate and present information from multiple sources on complex topics. Hence, assistance in the form of audio-visual aids like chalk and board, ppt and ohp is needed to enhance the quality of lecture. Aims and Objectives: The objective of our study was to find out medical students perspective regarding the 3 audio visual aids (chalk and board, ppt, ohp) commonly used in teaching. Material and Methods: A cross -sectional descriptive questionnaire based study was conducted on 87 first year medical students. A pre-designed, pre-tested, self administered questionnaire in English was used to collect data. A 15-item questionnaire was used to assess views regarding audiovisual aids. Statistical Analysis: Data was entered in MS Excel and were analyzed. Results are shown with the help of bar diagram, pie chart and percentages. Results: In our study, chalk and board was the most preferred teaching aid (62%) followed by combination of teaching aids(21.8%). 87.4 % students felt that chalk and board facilitated interaction of students and teachers, 81.7% for copying diagrams easily, 79.3% for better problem solving. The same parameters scored less with ppt, 3.4 %, 14.9%, 19.5% respectively. Our students felt black board was ineffective for demonstration of clinical conditions (98.8%), covering more subject per lecture (82.8%).These parameters scored highest preference with ppt teaching, 88.5% and 71.3% respectively. Conclusion: Chalk and board teaching remains as a best preferred teaching aid which can be supplemented by ppt and ohp to improve medical teaching.
