Comparative Effectiveness of Powerpoint Over OHP as an Effective Teaching Learning Tool at R.D. Gardi Medical College Ujjain (M.P)

Abstract

Background: Since years, a number of initiatives were taken to improve the teaching methodology in Medical
education.
Objective: The present study was undertaken to emphasize the importance of LCD-based teaching over OHP and
to increase teachers’ acceptability to LCD.
Materials and methods: This study was carried out with 100- 125 students. The study incorporated 50 minutes
teaching sessions in the department of physiology with the use of two different teaching tools. Students were
divided into two groups. One topic was selected and Roll numbers 1 to 75 were taught by Powerpoint by LCDs
& students from roll number 76 to 150 by Transparencies, in the second week they were assessed by written test.
Results: Significant difference in marks obtained by the students taught on PPT as compared to OHP(P>.001)
it was observed that students who scored less after OHP exposure showed improvement after PPT exposure.
(Table 1& 2) 80% of students prefer PPT over OHP and understanding of the subject was more with PPT. Students
found OHP good for the text material and insufficient for the applied and diagram part while preferred PPT for
3-D view of diagrams, concepts and applied.
Conclusion: In Department of Physiology at our Institute most preferred TL method was found to be by PPT then
OHP. As results also indicated improved performance by the students, In view of that Teachers also agreed to the
responses by the students, and showed acceptability for PPT.
