i>clicker, an innovative classroom technology invented by Illinois physics faculty, is continuing its successful trajectory in the commercial world. A team of four University of Illinois physicists invented i>clicker in response to curriculum reform begun as a result of physics education research. Because of a need to poll students, they began to try a variety of methods ranging from flash cards to hand-made clickers. They sold the easy-to-learn, easy-to-use i>clicker system to Macmillan in 2005.
Two of the inventors, Tim Stelzer and Mats Selen, remain key visionaries, active members of the product development team, and are heavily involved in all product decisions and the overall vision of the software and hardware. They also continue to travel for i>clicker pedagogical training sessions as i>clicker deploys in more educational venues.
To date, thousands of higher education faculty have implemented i>clicker in their classroms, and it is used by more than 500,000 students in North America.
