Nonsense. What are middle school classes...half an hour? Forty five minutes? An hour, at most. Kids who ride the regular bus easily remember to do what they hafta between classes.
That's what we're talking about here. The kids who ask for a hall pass while the teacher's standing up front going "blah de blah." If you have to do that 15 times a month, if nothing else, you've missed over an hour of information.
