David Kellermann (Engineering, UNSW) turns a 500-person lecture into individual learning. The tech to do it is now open-source
Dr Kellermann demonstrated how he does it at a Microsoft conference last winter (CMM July 19), showing how students in a lecture can ask a question live on-line and get a direct response from classmates and tutor, using QBot, which he built using Microsoft Teams.
QBot also archives questions and answers to build a course database.
An open-source version is now available.
