Trials at Northwestern University and Virginia Tech with videoconferencing in classrooms have been less than overwhelmingly successful. That's not to say that technology won't have an impact, but it's going to come from enhancing and improving the existing structure, not throwing out schools or teachers. Computers replacing teachers is not a useful goal. That's where I see the real changes in education. Home life isn't segmented into 50 minute period that start and end with bell ringings.
Education is life.
The really tremendous potential for educational technology is for adults, in many ways. Gerhard Fischer of U. Colorado-Boulder has been pushing for years the integration of learning and work. When something stumps you at work, you want the opportunity to learn then , immediately, at your desktop. I've been intrigued with the idea of having classrooms in the workplace, that work over time when learning can be most effective, not crammed into two days that are too soon forgotten. A month of intense presentations and discussions could be relatively time efficient and lead to great learning, new partnerships, and great fun.
