I've just started substitute teaching, and there is one thing that is driving me batty whenever I go into a local middle school. For some reason, the school invested in giving every student a tablet (even though the textbooks are falling to pieces, but that's another rant of things that make me crazy). Every day has at least one class with the trouble-making students, and always at least one of them whips out their tablet to watch music videos on Youtube during class. Why do they think that it's acceptable? Sometimes they don't even bother to turn the volume down, so I can hear it loud and clear, then they have the gall to look shocked when I tell them to turn it off and put it away.
Though another thing that drives me batty is schools getting a grant or good source of funding and then the Powers That Be spending it on something not school-related. When I was in high school, we had to do with dilapidated, out-dated text books and a copy machine so old and worn-out that the ink would come right off the paper onto your arm if you leaned on it. If you kept your assignments in a vinyl binder on a warm day, you wouldn't be able to do them at all, because half the words would be on the inside of your binder. But we had a state of the art weight room (forbidden to all but the school sports teams), a new electronic score board, and brand new uniforms for the teams every year. I went to school in a pretty rich county, with a terrible sports program that lost constantly and wasn't really bringing in any revenue, but for some reason, every time the school got funding, they saw fit to spend it on the sports programs. It made me crazy then and it makes me crazy now. If your text books are so old and torn-up that they barely have covers, why do the kids need iPads that they can access Youtube on? Wouldn't eReaders loaded with texts have been a wiser investment?
