Designed to accompany four filmstrips, this manual was developed to help early childhood educators--including curriculum specialists, administrators, teachers, and university faculty--implement a developmental program for young children. Filmstrip 1 introduces six components of curriculum organization and classroom mangement underlying a developmental approach. The three curriculum organization components (learning centers, skills groups, and units of study) and the three classroom management components (color coding, contracts, and internal and external discipline techniques) are defined and illustrated in a multi-age kindergarten/first-grade classroom. Filmstrip 2 follows a first grader through his daily activities in a variety of learning centers, math and reading skill groups, and social studies, emphasizing the application of curriculum organization and classroom management components. Evaluation techniques are additionally recommended. Filmstrip 3 details techniques used to implement an experiential, hands-on approach for teaching social studies and science concepts to young children through mini-lessons in home-based groups and through learning center activities. A unit of study in physical science titled "Moving Around" is presented as an example. Finally, filmstrip 4 reviews the rationale for a developmental approach and introduces methods for assessing the effectiveness of early childhood programs. A list of worksheets, sample worksheets, and a bibliography are appended. (MP)
