Through my personal observations, it seemed the use of PPT in my classroom decreased the amount of active learning taking place. The literature, on the use of PPT seems to support my observations that using PPT can lead to students becoming more passive in the classroom. So, in this two-semester project, I conducted classroom that tested the effectiveness of using PPT as a pedagogical tool.
I created PPT presentations that were short, brief, narrative and explanative-not a succession of unlinked terms in a series of bulleted or numbered lines. Students were exposed to two presentation approaches. In the first, they received printed PPT handouts and took short additional notes. In the second method, the material was presented with PPT without any printed handouts; students took all the notes, including the additional short explanative notes presented on the board with colored chalk. These two conditions varied by learning topics over two semesters to control for the effect of topic. The findings showed that students performed better on exams when they had not received not instructor-prepared notes, suggesting that having students take their own notes, in a fashion similar to taking notes in traditional courses, provides a greater opportunity for interaction between students and the instructor, and allows students to assimilate facts without losing the advantages of PPT.
