Pretzler Paper Take Home Message

I feel that there were several take home message within the Pretzler paper. First, it was very clear that the use of clickers was very well received by the students. Students felt that they were beneficial and made the lecture less monotonous. Secondly, there seemed to be an increased level of performance among the students, over all levels of education.

Finally, I feel that Pretzler made it very clear that it is very important to make sure that you are able to utilize the technology in a consistent and effective manner. It was mentioned that it is important to take time out of the first day of class to show the students how to use the clickers, therefore, decreasing the lag time during the semester.
