What I find most interesting about this is that most of the changes they implemented weren't necessarily targeted towards women and benefited everyone (emphasis on group work, research projects, splitting the into classes by experience).
emphasis on group work,
While I definitely experienced an unfortunate amount of "Pareto Groups" throughout my schooling, none of them were in the CS department at HMC.
It's not academic - but it definitely improves coding ability.
I'll take exception to the first example: group work. I loathed and hated group work in college. It was simply and solely a way for people who couldn't hack the course material to manage a pass anyway. This might, of course, be good experience for life, but it's terrible for education.
Research projects could be really, really good if they demand concrete results; they could be really terrible if they are just a way to reward effort without results.
Splitting classes by experience might be a decent idea, although I've heard folks speak positively of one-room schoolhouses as well.
