Evaluation of the Impact of Different Health Education Methods in Undergraduate Students of Dental College, Mathura City

Abstract

Aim: To assess the impact of three common lecture delivery methods viz. the lecture using pamphlet, the lecture using power-point presentation, and the lecture using audio-visual aids in undergraduate dental students of K.D. Dental College, Mathura. Materials and Methods: A total of 150 students were included in the study, i.e., 50 from each class and then divided into three different groups. Group I, Group II, and Group III used pamphlets, power-point, audio-visual aid as teaching methods, respectively. A questionnaire was designed and students were asked to fill it and also give suggestions as a part of feedback about the lectures conducted. Statistical analysis was conducted using student paired t-test and unpaired t-test, ANOVA and Fisher least significant difference post-hoc test. Results: Before intervention Group I obtained 4.38 +/- 1.67 mean marks, Group II obtained 3.22 +/- 1.47 mean marks, and Group III obtained 3.31 +/- 1.55 mean marks. The difference found between three groups was statistically significant (P = 0.05). After intervention Group I obtained 6.88 +/- 1.88 mean marks, Group II obtained 6.06 +/- 2.41 mean marks, and Group III obtained 6.00 +/- 2.05 mean marks. The difference found between three groups was not statistically significant (P > 0.05). Conclusion: The students preferred both audio-visual aids and power-point presentation in lectures than pamphlets. Since pamphlets were concise and get easily misplaced but other two methods were more interesting due to the incorporation of pictures, animations, etc.
