Despite their utility, traditional approaches to gauge student understanding and collecting their responses in class have multiple shortcomings. This paper discusses the shortfalls of these traditional methods (student raising hand, use of clickers, etc) and compares them with a new method (laser pointers used by students) that aims to solve the shortcomings of these popular methods. I have used this method in some of my classes with largely positive results. I will discuss how this can been used and how it compliments many of the common methods currently in use, while providing superior functionality. [ABSTRACT FROM AUTHOR]
