I think this can be a large barrier for some teachers who are resistant to technology in the classroom. They see these technologies as replacing actual though. It starts with a calculator and goes all the way up to simulations and decision making software. Even "googleing" something has taken away the traditional research methods of books and libraries. To expand on this, it also replaces te way in which teaching is presented, which might scare off teachers. To many, a SMART board is just an overpriced whiteboard, and in there minds is useless because they can use a whiteboard much easier.
