Answer this as if you were wholly against using innovation, technology in teaching. I am curious to hear the excuses you hear, or the things you suspect people feel when resistant to implementation of technology.
"It's just one more thing I have to worry about doing every day"
"Because kids still need to learn how to do worksheets"
Have fun with it, but try to respond with what you actually see and suspect from your fellow educators. (I know we all resist this to some extent, but the fact that you are associated with a site/forum such as this denotes at least an emergent interest and support for progressive technology in the classroom).
