Alexandria, Virg., doesn't view laptops for every student in a high school as unalloyed joy. As usual, those trying to gain or continue funding state vague, unsupported details about advancement. I love how Don Knezek, chief executive of the International Society of Technology Education "cited statewide programs in Maine and Michigan, among others," which is hilarious, because every single result I've seen out of Maine--including in-depth studies--has inconclusive or subjective results.
And, as usual, teacher training has come long after computer deployment. "...some teachers say they have felt pressured to emphasize laptops, even when using them might not be the best approach."
