Having gone to the NCTM conference a couple of weeks ago, I am full of ideas. I had the chance to see the TI Navigator demonstrated in several sessions and can really see the opportunities for student growth using that kind of technology. What I like is the way I can monitor and observe what students are doing as they work through problems.
My biggest hurdle, of course, is money. The best technology pieces are individual and this system is expensive. Not that I am saying it isn't worth it. But I don't know where the average classroom teacher is suppose to come up with the thousands of dollars it will take to buy it and then more thousands of dollars to get a projector. I wonder how much impact there actually will be on student learning. Is it worth it?
At the same time, I've been using a Classroom Performance System for several months already. The ability to get student feedback with it is amazing and my students have responded quite energetically. We're sort of hobbled though...I can only project images through a mounted TV in my room. Again a video projector will cost thousands of dollars to buy and more than a thousand to install. While I don't doubt the positive impact on student learning with CPS and even my ability to figure out how to use it, where is a school or a district suppose to find all these dollars?
Can you imagine how much it would cost to have both a CPS and a Navigator system in a room? It begs the question...how much technology is enough and how much is too much.
