This document, a curriculum guide in home economics on child development, for secondary schools, is one of six guides developed for inservice teachers at Marianas High School in Saipan. The guide provides the rationale, description, goals and objectives of the program; the program of studies and performance objectives by levels; samples of lesson plans for effective delivery of instruction; and a listing of references. Levels cover concepts in child development at three stages: 2-5 years (physical, social, emotional, and intellectual development, routine care, sleeping habits, clothing, cleanliness, safety, and nutrition and health), 6-10 years (growth patterns, family relationships, nutritional needs, typical behavior of the older child, and early school years), and conception to age 2 (conception, prenatal care, the newborn baby, and toddlers). Activities are appended for each level. (CT)
