Teaching at any grade is isolating, and preschool teachers often have it the worst, but, says early childhood teacher Heather Duncan-Whitt, educators can be more effective when they find ways to collaborate. She shares her own success stories and lessons learned, as well as practical guidance for schools to initiate the collaboration that is essential to strong teaching and student achievement.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
