MSA Share:20 gives students the opportunity to share information about a relevant or interesting topic with their classmates. MSA Share:20s are done during the lunch hour. The speaker prepares and delivers a 20 minute presentation or interactive tutorial or walk through. Then, students have time to ask questions and discuss the topic.
Think mini TED-like talks meet Lunch-and-Learns: The audience learns something, and the speaker gets more presentation practice.
