A project is defined here as an in-depth investigation of a real world topic worthy of children's attention and effort. The study may be carried out by a class or by small groups of children. Projects can be undertaken with children of any age. They do not usually constitute the whole educational program. Younger children will play and explore as well as engage in projects. Older children's project work will complement the systematic instruction in their program.

The Project Approach refers to a set of teaching strategies which enable teachers to guide children through in-depth studies of real world topics. The Project Approach is not unstructured. There is a complex but flexible framework with features that characterize the teaching-learning interaction. When teachers implement the Project Approach successfully, children can be highly motivated, feel actively involved in their own learning, and produce work of a high quality.
