The other great thing about structured representations is they allow

of equations
by treating the thing like a physical puzzle. Likewise imagine
trigometric equations
being displayed in a structured interactive geometric form. Kids could
learn about
complex trigometric relationships without algebra...
You don't have to imagine it. Go look at GraphingCalculator on the Mac. (It's a desk accessory)
I haven't see it, but I talked to someone who had. It's just a graphing calculator that takes equations as input, right?
