Experiment in the classroom
Use Sonic Pi and Mehackit's material in music or math classes and show what you can create with Sonic Pi. Students are often excited about programming precisely because Sonic Pi is so much fun. Bring in a colleague or someone else to help out.
The Sonic Pi lesson starts off with teaching you how to play different melodies, go through various commands, and build rhythms. This is an easy way to learn the basics of programming, programming commands, and writing code. All these steps can be found at: http://sonic-pi.mehackit.org/
