During February 2009 school vacation, several teachers at the Billy Dalwin Pre-School of Temple Emunah in Lexington MA will travel to Israel to engage in a dynamic professional workshop with some of the best early childhood educators in Boston and Haifa. This 10-day study mission is the latest in the seven-year history of the Boston Haifa Early Childhood Educators (ECE) Exchange. The Exchange is a partnership between teachers and classrooms in both cities.
