Clickers

In a lot of college classrooms, they use clickers so that students can participate in lectures. I think this is a very useful tool, especially in large classrooms where participation would otherwise be very difficult. It can also help with taking attendance. I know that many teachers use these clickers to give quizzes over their lectures as well. While these clickers can occaisionally malfunction, for the most part they are a very effective way to encourage students to be involved in the material they are learning, and I believe they would also be effective in kindergarten through twelfth grade settings.
