The use of Audience Response Systems, commonly called “clickers,” has grown in recent years as instructors have discovered the dual benefits of interaction and accountability when teaching large classes. Caldwell (2007) has shown that “these systems are especially valuable as a means of introducing and monitoring peer learning methods”. MacArthur and Jones (2008) have found that students generally have a positive attitude towards clickers, as well as research indicates measureable increases in learning through the use of collaborative response systems.
