Seriously … why don’t math classes use computers? Excel, simple Python scripts, Mathematica / Sage, everything beyond the TI-83. Kids could be creating totally sweet visuals instead of cribbing formulae. And thinking instead of copying.
I can say from my experience teaching that giving kids some real data and having them muck around with it for an hour, was better than an hour of my lectures. (And guess what, they understood lecture better after they’d looked at real data.)
Why, why, why, why, why is maths education so senselessly, wretchedly bad?
