The Accelerated Reader program works just as well on an older 386 machine as it does on a new machine. Ask parents in your class if they have older, outdated machines you can use to run the AR program on. In my classroom I use two older computers, one for boys and one for girls. This allows more children to have access to the program during the day. Even better, if you don't want to spend your day solving computer problems, train a few experts for each software program who can assist students when they run into problems.
