My time at college has seen the use of several clickers for use in the classroom. However, most ran off of IR technology and was a PAIN to get an answer into the receiver, even with multiple receivers set up. The iclicker runs off of radio frequencies so you don't even have to aim for anything (a major problem with IR clickers) and it registers on the clicker that you have submitted an answer. This is another benefit, it will flash green if you have successfully submitted an answer, if something is wrong it will flash red. The automatic shut off functions are great for saving power. The teachers on-screen iclilcker panel is straight forward and simplicity at its finest. Start, Stop, once you hit stop theres show and hide. Hit show and you show the graph of how the students responded and you can project this on the screen so the class can see the results. Two semesters of extensive use with this clicker and I have yet to replace the batteries.
Of all the clickers I have used this one is certainly the best, and it is similar in cost to the IR clickers I have used in the past. Clcikers, in general are a benefit to the classroom I believe. They are for use in a larger lecture for the teacher to make sure the students are understanding what is being presented. The only problem with clickers is when the teacher doesn't know how to ask clicker questions, for instance every 2-3 minutes a new clicker question is asked for the duration of the class period. Overall, however, I think these are a great addition to the classroom to determine if the majority of the class is understanding the concepts. An example of the usefulness is when you see most students answer correctly (B lets say), but then the rest answer C and there is no in between. What one can do is address the issue for why students thought it may be C while not having to waste lecture time explaining why A was wrong when all students already understand A is incorrect. Great for science and physics based classes, perhaps others but these are what I know of. There have been several instances I have seen lecture time saved because the teacher was going to explain an answer but, because of clicker responses, realized they didn't have to.
