Incorporating elements of humanist, Piagetian, psychodynamic, and behaviorist perspectives of child development, this guide for preschool teachers explores several topics related to curriculum planning for 4-year-old children. Chapter 1 points out the significance of the curriculum study, defines terms, and identifies assumptions and limitations of the study. Chapter 2 summarizes different perspectives of human development, adopts an eclectic approach to curriculum planning, and discusses ideas about child development related to curriculum planning for 4-year-olds. Components of the curriculum are discussed which promote physical, socioemotional, and cognitive growth and development; suggested orientations for planning in each area of development are described. Chapter 3 emphasizes the importance of planning classroom observation and evaluation activities. In chapter 4 parent involvement in the preschool program is briefly discussed. A summary, as well as conclusions and recommendations, is provided in the fifth and final chapter. Related materials are appended, including samples of a plan for a year-long program for 4- to 5-year-old children, observation forms and checklists, and a developmental profile. (RH)
