The NSF 2015 Teaching and Learning Video Showcase: Improving Science, Math, Engineering Computer Science, and Technology K-12 will showcase cutting-edge NSF-funded work to improve teaching and learning, and will allow colleagues affiliated with MSPnet, CADRE, CIRCL, CAISE, STELAR, CS10Kcommunity, and ARC to view, discuss, and comment on each others’ work. It will also allow each project to disseminate their work to the public at large, helping NSF achieve its goal of broad dissemination of innovative work. All videos and discussions will be archived for future access.
