I was searching for this and it seems like Harvey Mudd has had some pretty good success in increasing the percentage of women CS graduates: https://www.latimes.com/local/lanow/la-me-ln-harvey-mudd-tec...
A bit more on operations, management, development and deeper technology. I think a clearer understanding of the different roles that people play in development of technology systems is important. Men and women typically have different personality leanings (that broadly overlap), and understanding different roles and their focus would allow for people to understand and better choose towards their own interests.
In media, a lot of the time all the roles in IT/Development are interchangeable and muddled and there's almost no insight into where one role might end and another might begin.
Media changes:
* Don't show techs/ops and programmers as interchangeable in practice * Don't make techs or programmers look uncool * Show more diverse techs and programmers in roles * Don't dumb down smart female characters (some seasons of Arrow) * Don't turn smart female tech characters out of tech (Daisy on Agents of Shield)
Education Changes:
I'm not sure here, between K-12 vs >12, as I really think better normalization in media would go a long way. I also think actual gaming with broader appeal is helping a lot too.
I do find it interesting that given college women outnumber men by almost 2:1 that the majority of STEM and more specifically CS graduates are men. I think that colleges really need to look at their own practices here more and that cuts both ways. I find a lot of modern progressive feminist extremism to be far different than any classic goal of equal opportunity which is disenfranchising.
