This in-service education module is intended to facilitate mainstreaming of young children with special needs in child care centers by providing information and training in mainstreaming concepts and activities to child care center owners, operators, and personnel. Guidelines for instructors in preparing for planned sessions are followed by a summary of intended outcomes and a glossary of relevant terms. Each of the 10 intended outcomes is then presented along with related performance objectives, activities, and resources (print and audiovisual). Among the topics explored in in-service activities are adaptations in the child care setting, child development and behavioral indicators of special needs, communicating with parents, individual differences and similarities, and mainstreaming-related management issues of concern to owners and operators of child care centers. Specific disabilities discussed include mental retardation, hearing and communication disorders, visual impairment, and movement disorders. Approximately half the document consists of the print resource handouts cited in the activities section of the module. References and a course evaluation form conclude the document. (JW)
