Abstract
Objective: To compare the impact of the Power Point multimedia presentation and chalkboard in teaching by assessing the knowledge based on the marks obtained.
Study Design: Cross-sectional study.
Place and Duration of Study: Department of Physiology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, from December 2007 - June 2009.
Methodology: Three-hundred male medical students were divided into three groups and a selected content-based lecture in physiology was delivered. For one group lecture was delivered using Power Point presentation, for second group using chalkboard and for third group the lecture was delivered by using both Power Point as well as chalkboard. Single-best Multiple Choice Questions [MCQs] paper was used for assessing the knowledge gained. The same exercise was repeated in another medical science school for the confirmation of validity and reliability of the results.
Results: Students who attended the class on both Power Point and chalkboard obtained significantly higher score in single best MCQ examination compared to those students who attended the same content based lecture on the Power Point or chalkboard alone (p = 0.05).
Conclusion: The integrated (Power Point and chalkboard) method of teaching was found more suitable tool of teaching and learning than Power Point or chalkboard alone.
