Computer Science Unplugged

“CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. We originally developed this so that young students could dive head-first into Computer Science, experiencing the kinds of questions and challenges that computer scientists experience, but without having to learn programming first.” —CSUnplugged.org About page

50 Women in the Tech Industry Every Man Should Know

To solve this problem, we’ve got a list of the top 50 women in the tech industry you should know about!” (Thank you, Eva!)

Tips for Getting Girls Involved in STEM

SAM Reader Brielle sent me this link from ITHARE.com. From the ITHARE About page: [They are a collection of] H.A.R.E.[s], which stands for “Honest And Restless Engineer”.
