During lunch at the March 2013 Scratch Educator Meetup, we hosted a session called Show & Tell. Structured as a series of quick, lighting-round presentations, educators are given the opportunity to share anything related to their work with Scratch in an informal group setting.
Show & Tell is a recurring session that takes place at the Scratch Educator Meetups, a free monthly event held every month at MIT. You can watch previous Show & Tell videos or register to attend the next meetup on the ScratchEd events page.
Lorraine Leo shared an interactive, large-scale Scratch project created in collaboration with Japanese Scratch educator, Yoshiro Miyata, and contributed to by teachers and students around the world including the United States, New Zealand, Australia, Thailand, and the Philippines.
Derek Breen described how he produced an awesome (and efficient!) space invaders game using the cloning feature in Scratch 2.0 and by remixing aspects of another Space Invaders-inspired project he discovered on the website.
