Rapid responders are the new classroom essential.
Walk the exhibit hall of any education technology conference today and you're sure to see more rapid response systems than you can count.
Yes, "clickers" have caught fire in the education space as tools that truly enable interactive, personalized learning in both classroom and professional development settings.
Clickers are individual handheld transmitters that collect learner input and pair with a host software system that electronically collects and tabulates that data for instant display on a computer monitor. For large group viewing, an LCD projector can be hooked up to the computer.
The three basic categories of clickers are Wi-Fi wireless, radio frequency, and infrared (see sidebar "Clicker Basics," this page), with operating systems and feature options varying.
Educators tout clickers for their ability to engage whole classes of students via ongoing question and answer activities, collect data in real time to assess the effectiveness of instruction, facilitate self-paced testing, collect large amounts of data on student performance, and to generate reports in a range of viewing options.

IR—infrared systems require an unobstructed line of sight bet ween transmitter and receiver. The more receivers in use, the more potential for signal interference. Be sure to research the classroom infrastructure before purchase, as integrating IR hardware might face challenges. Receiver wiring is simpler in small rooms with existing conduit runs available.
RF—radio frequency systems are not dependent on line-of-sight transmission, and single receivers may now work with more than 500 transmitters. Infrastructure issues are normally not major, and portable receiver units may be used. Be sure to check out nearby rooms and continue to monitor them for possible mutual frequency interference.
Wi-Fi—wireless systems can include everything from student PDAs to laptops to tablets, with individual Web browsers interacting with the host hardware. Management software may reside on the instructor's computer or a network server. Wi-Fi is a good choice if you're looking for interoperability with Web-enabled cell phones down the line.
