There is an increasing demand for computer science courses yet a shortage of teachers with the subject matter expertise required to teach these classes. The Microsoft Philanthropies TEALS Program provides a short-term solution to the teacher shortage and helps schools build a long-term and sustainable computer science program by partnering teachers new to computer science with industry volunteers who have computer science content expertise. Teachers in these partnerships learn computer science while team-teaching with volunteers until they are comfortable teaching independently. In this session, participants will hear about the Microsoft TEALS approach and discuss how industry volunteers can make an impact in a computer science classroom.
