Functional decomposition and logic

Students found it much easier to work with methods and parameters when
doing programming exercises. Also, ASCII drawing exercises drew their
attention. We should emphasize this in CS21A next semester.

Not that I’m too fond of focusing on structured programming, but
they’re no longer worrying about syntax _and_ they feel challenged and
happy, so it can’t be entirely a bad thing. They don’t seem to mind
working on toy problems, either.
