Summarized are implications of recent research on children's development and learning for the curriculum in early childhood programs. Contents focus on the development of language, dispositions, social competence, and intellect. Taken together, the research suggests that children attending preschool and kindergarten classes should frequently be provided with opportunities for involvement in projects. A project is defined as a group undertaking, usually concerning a specific theme or topic, which requires various kinds of work over a period of several days or weeks. Concluding remarks identify three basic kinds of projects and three phases of project work. A three-page list of references concludes the document. (RH)
