These include teacher resistance to change, especially (change mandatedtop-down changeby school administrators with little or no input from teachers),
When we consider why tech in education didn't live up to its high expectations, I wonder how much of it was because the technology wasn't effective and how much of it was because the failures to implement them correctly--not addressing teacher's resistance to change, implementing it from the top-down without input from the teachers. What I'm trying to get across is the lesson: we need to address people's resistance to using technology for learning or not be overly optimistic about the usefulness of tech in edcuation.
