Two Column Proof
Posted:
Jul 19, 2006 11:49 PM


This is not a facetious question. Let me just state that outright.
Why do we teach twocolumn proof?
Note that I am not asking why we teach reasoning, or proof in general. I feel that is important. I am just a little shaky on making everyone learn twocolumn proof.
I would love some feedback!
Thanks!
