Abstract :

Introduction: Pharmacology teaching lectures were based upon teaching aids like chalkboard, PowerPoint (PPT) but the superiority of these aids over one another has not been proven. The present study was conducted to evaluate the impact of the PPT and chalkboard based lectures in pharmacology teaching on medical students in Government thiruvarur medical college Material and methods: Study was conducted at Department of Pharmacology, Government thiruvarur Medical College, Tamilnadu, India in 2017. Ninety nine medical students of second MBBS were randomly divided into two groups and a selected content–based lecture was delivered. For one group lecture was delivered using chalkboard, for second group using PPT presentation. Single–best Multiple Choice Questions [MCQs] paper was used for assessing the knowledge gained. Two direct question to note student preferences for these aids was included on the MCQ paper. The difference in the marks obtained in the two groups was analyzed by unpaired student’s t test. Results: Students who attended the class using chalkboard obtained significantly higher score in MCQ test compared to those who attended the same content based lecture using PowerPoint (p=0.035). The power point lectures were preferred by 60 % of the students. Conclusion: The results of the present study suggest power point based lecture were preferred by students than the chalk and talk lectures. The scores obtained by students in chalk and talk were more than the power point based lectures
