Impact of Use of Audio-Visual Aid on Dissection Hall Teaching

Dissection hall teaching, which is a backbone of teaching and learning Anatomy, is suffering a lot due to dearth of faculty members as MCI has reduced the number of teachers required per hundred students. In lack of proper guidance and clear instructions students are gradually losing interest in dissection, therefore we thought of using audio-visual aid as an adjunct for Dissection hall teaching. 250 MBBS students of 2015 batch were taught lower limb in dissection hall in traditional way. While teaching neuroanatomy, 5 classes were taken by A-V aid in which features of brain were shown to the whole batch. After completion of each part, an OSPE was conducted of 50 marks. To observe the impact of this teaching on the performance of students, marks of both the tests were compared. A feedback questionnaire was also filled by students after completion of neuroanatomy. The average score obtained by students in lower limb was 21.30±7.07 whereas in neuroanatomy it was 26.35±8.41 and the gain in the marks was statistically significant. The percentage of students who secured less than 50% marks decreased from 66.95% to 43.64%. Feedback analysis showed that 94.53% students found the pre-dissection demonstration very useful. 92.08% students agreed that it helped them in understanding inter-relations of structures. Thus the teaching intervention by using A-V aid as an adjunct was very effective in giving uniform instruction to the UG as well as PG student and in enhancing the understanding of subject.
