They aren't just used in universities! (Score 1)

I know the article focused on using the "clickers" in college level courses but they are being introduced and used quite successfully at lower education levels as well. I teach Kindergarten and use them with my students from time to time. In the smaller classroom setting, I have no more than 22 students, there aren't any problems with the signal not working or with the device recording the responses inaccurately. These "clickers" have been an excellent way to get all children actively involved in the classroom discussions and it is a very simple way for me as the teacher to get a quick check on what percentage of the class is "getting it". Just thought I would offer a slightly different viewpoint - the "clickers" are getting children excited not only about using technology, which is very important, but also about the learning!!
