Background: Very few studies have been done to assess perceptions of teachers and considering diverse views about teaching methodologies, this study was carried out with objectives to assess preferences of medical teachers for the use of audiovisual aids in lecture delivery as well as practices of medical teachers regarding use of audiovisual aids.
Methods: This was a questionnaire based study conducted among the faculty members; teaching the medical undergraduates in various departments of SRTR GMC, Ambajogai. The study was carried out using predesigned, pretested questionnaire made for this study. The members were asked to fill in the structured questionnaire about their utilization and perception of the various methods of lecture delivery, viz: Chalkboard, Transparencies and OHP (TOHP) and the PowerPoint (PPT) presentation and combination.
Results: In our study, majority of the teachers (45.37%) used chalkboard followed by combination of
ChalkBoard and TOHP/PPT (29.63%). PPT alone was used by 13.89% of participants while TOHP was used only by 11.11% participants. Most preferred method of teaching was combination of ChalkBoard and OHP/ PPT (46.30%) followed by PPT alone (32.41%). ChalkBoard method was preferred by 16.66% participants and TOHP was preferred by only 4.63% participants.
Conclusion: The result of the present study suggests that the dominant form of lecture delivery is still the chalk and talk approach. However, each teaching aid has unique advantage and combination of ChalkBoard with PPT or TOHP is most preferred medium. There is unmet need of formal training in teaching technologies to develop good presentation skill.
