"A project is an interdisciplinary study of a particular topic that one or more children undertake... Work on a project might extend over a period of days or weeks, depending on the children's ages and the nature of the topic... Projects usually involve children in advanced planning and in various activities that might require several days or weeks of sustained effort. This approach emphasizes the teacher's role in encouraging children to interact with people, objects, and the environment in ways that have personal meaning to them. As a way of learning, it emphasizes children's active participation in their own studies... An overall aim of this approach is to cultivate the life of the young child's mind. In its fullest sense, the term mind includes not only knowledge and skills, but also emotional, moral, and aesthetic sensibilities."
