For anyone inquiring, I KNOW THE PERFECT ONE FOR YOU!!! Please take my advice... I am a recent college graduate and have used this system and think it is the best since thing since sliced bread. Not to mention, FREE! H-ITT, Hyper-Interactive Teaching Technologies, are the pioneers of classroom response systems. The idea was created by two University of Arkansas PhD Professors and a few years later, bought out by the product manufacturers. H-ITT's products are the most flexible, simple and inexpensive classroom response system on the market.
H-ITT offers class packs of IR and RF remotes, as well as SoftClick, a system where any web-enabled device is your clicker. Here's quick price comparison: eInstruction 32 RF pack, $2995; IR $1995. Turning Point receivers are $695 and each extra remote is, IR $49, RF $89; H-ITT 32 IR $795, RF classroom packs go for $1395.
If you are a K-12 teacher, you can get it for free with a grant. If you are a higher ed teacher, your receiver is free and you tell the bookstore to purchase x number of clickers for your students. This is all no cost to you. Please take a look at the website,
www.h-itt.com, and check out the versatility and usability of this system. If you are interested, I can get you set up with a system in your classroom to try out for 30 days, no cost. If you like it, H-ITT will help you write a grant or place an order. Everything to do with H-ITT is so easy. Feel free to contact me ANY time, cnewberr@mail.usf.edu and I would be glad to get you immediately in touch with someone who can get you set up with one of these systems.
I'm a real user/advocate of the system and I want everyone to know!!
