Perception of medical students on usefulness of interactive lectures: Can it be a welcome change?

Abstract

Background: Interactive lecture is a student centred teaching technique incorporating, multimodal strategies to create more engaging classroom settings. In our medical college, traditional lecture approach has been the core teaching method. So, we intended bringing in a change to passive way of learning by introducing first interactive lecture in Microbiology. The objective of our study was to evaluate perception of students on the usefulness of interactive lecture over traditional lecture. Methods: A session on Laboratory Diagnosis of Hepatitis B virus was selected. Anonymity of the responses was ensured to the students. Students were given overview about the study design and purpose of the study. Those who are willing to participate were enrolled for the study. A total of 112 students given consent were included. It was planned to provide traditional lecture on the selected topic followed by interactive lecture on the same topic for all 112 students. At the end of both the session, cross sectional survey was conducted using a pre validated questionnaire to assess the usefulness of interactive lecture given. Responses were to be provided on five point Likert scale with a score of 1 = strongly disagree, 2 = Disagree, 3 = Neutral, 4 = Agree and 5 = strongly agree. Frequencies of responses were analyzed by merging SDA and DA (Strongly disagree and Disagree) and SA and A (Strongly agree and Agree) as two groups. Percentage of responses was compared. Results: In general, 96% of them perceived interactive lecture was useful and reported that they strongly recommend it to their friends who werent there. Out of 112 students, 94(84%) reported interactive lecture was interesting when compared to traditional format. Conclusion: When planned meticulously interactive teaching can definitely can save time and energy. Our study emphasizes the need of interactive lecture in core curriculum for better understanding of the subject.
