The last two years, we've seen a huge increase in enrollments in our introductory computer science course. Last year it was about double the size it was the previous year; this year, it looks like it's gone up another 50%. Yes, the intro course has about tripled in the last two years.
Part of that might be that we have a new instructor, who is apparently young, dynamic, bringing a more modern perspective, and all those things that inspire students to take introductory courses. Another explanation is that Harvard last year introduced minors (called secondary fields), so now by taking 4 classes you can get a minor in computer science. A more timely explanation is that the financial meltdown is encouraging students to look at computer science and applied math this year (instead of the more commonly popular major of economics).
The gain is starting to translate into other courses. The intro theory course (automata/complexity) is up over 50% from last year.
Needless to say we're excited by this change, although still processing what it means and how to deal with it longer term. Obviously, we're hoping this will help us make the case for more hires...
