Comparison of Teaching by Conventional Method and by using Cognitive Theory of Multimedia to Post Graduate FCPS Radiology Students

Abstract

Abstract:

Objective: Objectives of this study was to teach postgraduate radiology resident physics by both conventional method and by using cognitive theory of multimedia, comparing the results and to see if there was any improvement in their learning and performance.

Study Design: Comparative Experimental study

Setting and Duration of Study: This study was carried out at B.B.H. and Holy Family Hospital Rawalpindi from Oct to Dec 2019.

Methods: Two groups of PG FCPS students of first year and second year comprising of 10 students each were formed. Two groups had similar attributes. First of all Pretest is taken. Group one was taught through didactic lecture and post test was taken. Second group was taught by the use of cognitive theory of multimedia and post test was taken. Cross over was done. Pretest was taken as before. Group one was now taught by the use of cognitive theory of multimedia and post test was taken and group two was taught through didactic lecture and post test was again taken. Results of both groups were compared.

Results: Statistically these two groups were similar. At the end of first round mean pretest score in conventionally taught group I was 4.1 and mean post test score was 8.8. In group II taught by cognitive theory of multimedia the mean pretest score was 4.2 and mean post test score was 13.3. After cross over in group II taught conventionally the mean test score was 4.0 and post test score were 8.9. In group I now taught by cognitive theory of multimedia teaching group mean pretest score was 4.1 and mean post test score was 13.6.

Conclusion: Postgraduate, first and second year Diagnostic Radiology residents performed better in assessment once they were taught Physics by use of cognitive theory of multimedia as compared when taught by conventional method of teaching.
