This booklet, one of a series of 34 on promising programs in childhood education prepared for the White House Conference on Children, December 1970, describes the Philadelphia Teacher Center--a staff development program which provides a place where teachers can make things for their classrooms and exchange ideas with others. The Center provides the teachers with materials and tools and conducts workshops. Teachers can come to the Center on release time or after school to make educational games and materials for their classrooms. The Center contains examples of things that can be made with the materials provided and a library of professional books and manuals with ideas for learning games and materials. (RT)
