to increase teachers’ acceptability to LCD.
Materials and methods: This study was carried out with 100- 125 students. The study incorporated 50 minutes
teaching sessions in the department of physiology with the use of two different teaching tools. Students were
divided into two groups. One topic was selected and Roll numbers 1 to 75 were taught by Powerpoint by LCDs
& students from roll number 76 to 150 by Transparencies, in the second week they were assessed by written test.
