The only thing more misguided than a person who doesn't see the value of an interactive whiteboard in a classroom is the person who thinks they belong in every classroom.
As I have blogged about in the past, I have an interactive whiteboard in my classroom and I feel it has transformed my teaching. I have heard the opponents say that it is just another way to have the 'sage on the stage' and, as I have said before, I am rarely in front of the board. I typically have the students at the board and I sit between some disruptive students with my portable slate. If you go back to educational theory, you will find that kinesthetic and visual kids will find a comfortable adaptation to learning with an IWB. I can't imagine going back to teaching without the board.
One thing I keep reading and hearing about administrators who make a major purchase to buy one for every classroom. Misguided is the best thing I can say. Anyone adept in education understands that not all students learn the same way. In addition, all teachers are prepared to teach in that way. The boards should be carefully purchased and dramatically infused into classrooms and curriculum.
