Background: Every teaching technique has its limitations and the need to evolve with changing times is required. A combination of these techniques may be useful to solve the problems that these methods have individually. However, there are no studies which provide a comparison between the three modes of teaching, that is, blackboard and Power Point presentation (PPT) combined, blackboard only and PPT only.
Aim and Objectives: In this study, we aim to find out the difference between the three modes of teaching, that is, blackboard and presentation combined, blackboard only and presentation only in terms of academic performances of the students in the subject of pharmacology and the feedback received from them.
Materials and Methods: The total batch of 150 students was divided into three groups of 50 students each. Each group was taught one topic through only one mode of teaching such that alternatively every group is exposed at least once to every mode of teaching. Pre-test was taken from all students before the start of the topic and post-test was taken after the end of the topic. Every group also filled a pre-validated feedback form with answers in either yes or no, at the end of the topic. The data were analyzed between the three groups in the form of percentages. One-way ANOVA test was used to find the comparison between mean values of marks scored in the tests and feedback between the three groups.
Results: Blackboard and PPT combined (96.05%) received the highest positive feedback response followed by blackboard only (90.48%) and PPT only (87.42%) modes. The average scores in all the post-tests in all groups were higher than the pre-tests score;, however, the difference between them was not significant.
Conclusion: In this study, we conclude that the combination of blackboard and presentation technique is the best mode of teaching to the students in the subject of pharmacology because it provides the interaction of classroom as well as the visual aid of important topics and images.
