Seth V, Upadhyaya P, Ahmad M, Moghe V - Adv Med Educ Pract (2010)

Bottom Line: The medical students clearly preferred the use of PPT presentations while the dental students did not.The study does not bring out evidence based superiority of any lecture delivery method.It appears that in the hands of a trained teacher any teaching aid would be appropriate and effective.

ABSTRACT

Purpose: To assess students' perceptions of the impact of PowerPoint (PPT) presentations in lectures in comparison to the traditional chalk and talk method and lectures using transparencies and overhead projector (TOHP). The study analyzes the preferences for teaching aids of medical students versus dental students.

Methods: Second year medical and dental undergraduates were asked to fill in a nine-item questionnaire about their perceptions of the three lecture delivery methods. Following analysis of the questionnaire the students were interviewed further. The results were analyzed separately for medical and dental students to see if there was any difference in their perceptions.

Results: The majority of the medical students (65.33%) preferred PPT presentations, while 15.16% of students preferred the lectures using chalkboard, and 19.51% preferred TOHP for teaching (P < 0.001). Of the dental students: 41.84% preferred chalkboard, 31.21% preferred TOHP, and 25.85% students preferred PPT presentations in the lectures (P < 0.05). Some important comments of the students were also recorded on interview which could be valuable for the medical teachers.

Conclusion: The medical students clearly preferred the use of PPT presentations while the dental students did not. The study does not bring out evidence based superiority of any lecture delivery method. It appears that in the hands of a trained teacher any teaching aid would be appropriate and effective. This highlights the need for formal training in teaching technologies to develop good presentation skills and thus motivate the students.
