Through the use of a long-term project in a graduate teacher education course on the importance of play, students learned skills beyond those usually required in a graduate classroom. Students used their understanding and knowledge of play, constructive practice, and project work to develop a family play day at the university lab school. As part of the project, students helped to develop a play-style instrument that served as a self-study for their own classrooms as they observed the play among their own students. The project culminated with the students hosting the families of the lab school at a fun day and preparing a brochure that gave families information about the importance of play.
