- ...I seem to have started an interesting discussion. I should make it
- absolutely clear that:
-
- My views are my own and do NOT represent those of the University of
- Bath School of Mathematical Sciences
-
- That said, I agree that it is more important to understand the meaning of the
- operations than carry them out like a trained monkey. The point is that when
- faced with a new concept, IMHO the best way to understand it is to work through
- some easy examples, and then test that understanding with some harder ones. If
- students get into the habit of thinking about things such as limits rather than
- running to the nearest machine and asking it to do the problem for them they
- may actually turn into mathematicians. But if all that is taught in
- undergraduate mathematics courses is what buttons to push then the people that
- emerge from those courses will not be mathematicians. I don't think this is
- such an antedeluvian view! The problem that started this thread off was a good
- example of a pretty argument that those who misuse computers would have missed
- out on.
