If you must have computers in the classroom, then put them in the classroom. Give the students a flash drive to move their work to their home computer. That's what they do at my daughter's high school. They assume she's got a computer at home, and they require her to have a flash drive. Now, of course, there are some (30%?) students who don't have computers at home. Instead of giving every student a laptop, give those with no computer at home a desktop for home for the year. They're cheaper than laptops, and you only "give" them to those who need them. Not that this old drop out from the 60s can see the need for computers at school, anyway. Particularly PP.
