I’ve been doing a lot of research on the various SRSs lately. They tend to be expensive, around $30-$40 per clicker for a capable system. I perceive the leaders to be TurningPoint, Interwrite PRS, and Quizdom. For a little more money, smart classrooms systems like Promethean Activote and SMART Senteo are available. There’s just tons available however: H-ITT, iRespond, Quicktally, iClicker, Optivote…. and I haven’t even mentioned the ones aimed at businesses!

I’m a student at MIT. The high cost of clickers motivated my friends and I to build PollEverywhere.com. It uses student cell phones as clickers. Students pay only normal text messaging charges, about $.01 per response. We priced it to be free for K-12, but it always comes out cheaper than hardware, usually at about 10% of the cost. We don’t have all the features you’ll find in TurningPoint, but many professors find they don’t end up using all the feature anyway. A professor at the University of Florida uses Poll Everywhere prolifically for 3 sections of about 180 students each. Please get in touch if you’d like to know more about it, or any of the other SRSs out there.
