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.
