This article from The Economist is a great read on using Hip Hop as a vehicle for teaching students about technology:

Spitting Lines - How hip-hop is introducing children to coding and technology.

It talks about classrooms in New York, Spotify and Tumblr sponsored hackathons, and potential future events with Rap Genius.

I love this combination of Hip Hop and technology and the positivity behind it. Please checkout Hip Hop Hacks especially if this inspires you.
