Friday Hack Chat: Making Electronics for Education

For this week’s Hack Chat on Hackaday.io, we’ll be talking with AnnMarie Thomas about making electronics for education. There’s a huge intersection between electronics and education, and whether you’re designing robots for a FIRST team or designing a geometry curriculum around 3D-printed objects, there’s a lot electronics can teach students.

AnnMarie Thomas is an associate professor at the School of Engineering and the Opus College of Business at the University of St. Thomas. She’s the founder of the Playful Learning Lab, and along with her students she’s created Squishy Circuits. AnnMarie is the author of Making Makers: Kids, Tools, and …read more http://pje.fyi/PXCJhh
