Upon completion of this learning unit on parent/teacher/community relationships, Child Development Associate (CDA) trainees will be better able to (1) promote positive functioning of children and adults in a group, (2) bring about coordination of home and center practices, and (3) carry out related, supplemental responsibilities. Information is provided in Chapter II on involving parents in program enrichment, using effective meeting techniques, and communicating with parents. Chapter III consists mainly of information on using volunteers to help promote program enrichment. Community involvement in the early childhood program and delivery of health and social services is discussed in Chapter IV. Chapter V provides guidelines for setting up an activity card file, indicates components of activity and resource unit cards, and provides samples of each. The organization of a resource file is also discussed. The final chapter, Chapter VI, focuses on CDA portfolio development in the area of home/center coordination. (Author/RH)
