To find out the better teaching technology among Chalkboard and Power point. Objective: To assess and compare the impact of Chalkboard and Power point teaching Method: Hundred and seven (107) VII semester students were randomly grouped into two on date 09.07.2013 in period allotted for PSM Teaching by the Principal and Controler SMS Medical College, Jaipur (Rajasthan) India. Pre-test of both the groups were taken through a written assessment on Multiple Choice Question (MCQ) pre-designed by National AIDS Control Organization (NACO). Out of these two groups, one group (Gp ‘A’) were taught Sexually transmitted diseases though chalkboard whereas 2nd group (Gp ‘B’) were taught Sexually transmitted diseases though Power Point. After that post test was taken of both the groups. Impact of both the groups was assessed and compared with Paired and unpaired‘t’ Test. Result: Time taken was more to teach the same content by Chalkboard method than Power point method i.e. 55 minits V/s 38 minits Mean change in score of marks after lecture was significantly more (P<0.001) in group with power point teaching than chalkboard teaching (22.3±12.4 v/s 7.9±11.1). Change in proportion of passed students were also significantly (p=0.005) higher in in group with power point teaching than chalkboard teaching (57% v/s 36%) Conclusions: Power point teaching is better than Chalkboard teaching. Power point teaching is more scorer and less time consumer than chalkboard teaching .
