(a) The two are not unrelated. After all, the technical proof is just a
very abstract explanation. While one would certainly not give students the
abstract proof, it may be helpful in developing useful ideas at a more
concrete level. My belief and experience is that if I don't really
understand a concept at a level appropriate for me, I am not likely to be
able to develop reasonable ideas for my students... necessary but NOT
(b) I like your ten questions! They'd be great for secondary PST's!
