Analysis of learning by doing in the creation of instructional video in teaching optics

It is well known that videos in education have some advantages in specific areas. We have made the experiment to see the effect of video in physics education. Our goal was to see if short video clips can improve understanding of physics - optics. In our experiment we wanted to test the principle “learning by doing” with the specific emphasis on creativity. Students were divided into two separate groups with the same assignment. First group was to prepare a video without any additional instruction from lecturer but they were not limited by any other means. The second group was further divided into two teams. Both teams got the same instruction how to create educational video clips. The difference between these two teams was that one team was given the detailed analysis of previously created bad educational video on the same topic while the other did not. Since creativity cannot be though and has to come from the individuals own inspiration we wanted to know if too many instructions actually influence the outcome of the students´ performance.
