Wyzrr provide the instructor with a real-time, versatile virtual clicker system, and its potential uses are many. From a pedagogical point of view it can be used as sample on-the-fly check wither students have understood and gotten the key message of your lecture.
It can also be part of a more intricate pedagogical method, such as the peer instruction approach, as proposed by Prof. Eric Mazur, among others. In this context Wyzrr would be used as an in-session quiz to provide the instructor with information on which concepts to tackle and to stimulate classroom discussion.
