Recently we have been working with Smartkids to bring the RPiSoC into the classroom. Last week we ran our first trial run at Glenmont Elementary school with over 60 3rd graders. A quick summary from the school district can be found here: http://www.bethlehemschools.org/3rd-grade-students-dabble-code/
These demos made use of Scratch on Raspberry Pi and Windows. Kids learned how to control LEDs, use capacitive touch sensors in a game, and control servos and joysticks. We will be doing several more demos at schools in the next few months. This will allow us to get the feedback we need to add some final polish before we release kits.
