I am an organizer and instructor for the local Ottawa branch of Girl Develop It, which is lead by Serena Ngai. As described on the main webpage:
It can be intimidating for women to learn and ask questions when they are in an extreme minority. While open and welcoming, today's budding developer community is up to 91% male. If we can empower more females with the confidence in their technological capabilities we can begin to change this landscape.
You can follow the happenings of Girl Develop It Ottawa via Meetup, Facebook, Twitter, or Tumblr.
Intro to Scratch Programming
To kick off the new chapter, we decided to host a free, three hour workshop that introduced programming in Scratch, a popular visual drag and drop interface.
I designed and lead the workshop with great success. You can download the slides and notes (PDF, PPTX), and read about our experience from my perspective and Serena's.
