TEALS (Technology Education and Literacy in Schools) is looking for volunteers for next year to help teach Intro and AP Computer Science in high schools. TEALS is part of Microsoft's YouthSpark program, and is run and funded by Microsoft.
I currently am a volunteer for TEALS, teaching Intro to CS to high school students. If anyone is interested or has any questions about my experience so far, let me know!
