Many teachers are using Twitter as a classroom tool. But a lot of schools still view the communication tool as a "toy" students use in their free time, not a serious platform for learning. As sites like Twitter and Facebook become ever more fundamental to how the world communicates, schools will need to shift their policies to move with the times. An article written by KQED's Education department in collaboration with the Trust and Safety Team at Twitter helps educators understand how to keep themselves and their students safe on Twitter. It also pulls together great resources on digital citizenship, basic Twitter info and ideas on how to use Twitter in the classroom.
