Too long for a tweet; not really worthy of a blog post. Here goes anyway…
I just walked past a computer science classroom, where the instructor was drawing an elaborate set of diagrams—presumably representing subroutines and whatnot.
Students were dutifully taking notes.
I thought quickly to myself, How effective can this possibly be? Don’t you have to learn programming by solving problems?
And then I thought to myself, a bit more slowly, And how is mathematics any different?
