One of a series of 18, this Child Development Associate (CDA) training module provides a guide to the construction of learning centers in preschool settings. Upon completion of the module the CDA trainee is expected to be able to analyze and improve the arrangement of space, materials and equipment; specify and rotate learning centers in the available space; inventory materials and equipment; plan, execute and evaluate learning experiences in each different learning center; evaluate learning center effectiveness; and understand the importance of learning centers for child development. After a statement of rationale, objectives and self-evaluation procedures, the module gives an overview of learning centers and then focuses on specific kinds: art, block, dramatic play, language arts, mathematics, music and science centers. The overview discusses the physical arrangement of learning centers, their value, scheduling and selection, and the teacher's role. Each kind of center is discussed in terms of physical arrangement and selection of materials and equipment. Sample listings of materials and equipment for each center are provided. Also included are lists of supplemental reference books, pamphlets, children's books, films, filmstrips and cassette tapes about early childhood education. (RH)
