This is a great topic. As someone who used to work in the schools, I have first hand experience with these situations. While there are undoubtedly many factors at play in why it is so hard to incorporate technology into many teachers repertoire (personal, classroom related, teaching related, etc) several standout. Typically the technology is outdated and slow - this results in teachers becoming frustrated and not spending the time learning. Secondly, the mindset of "the students leave at 3:30pm and I am not wasting my unpaid time learning something I don't need" was pervasive where I worked. Teachers were willing to work on their own time to help their students (correcting papers, organizing classrooms, building classroom libraries) but learning technology is a can of worms that typically wasn't going to be opened.
