This competency-based secondary learning guide on strengthening parenting skills is part of a series that are adaptations of guides developed for adult consumer and homemaking education programs. The guides provide students with experiences that help them learn to do the following: make decisions; use creative approaches to solve problems; establish personal goals; communicate effectively; and apply management skills to situations faced as an individual, family member, student, and worker. Each learning guide includes these sections: a general introduction and guidelines for using the material; a checklist for users for advance planning; introduction to the guide; specified competencies, with student outcomes/evaluations, definitions, key ideas, teacher strategies/methods, suggested student activities, sample assessments, and supplementary resources. Three competencies are addressed: explain the nurturing roles and responsibilities of parents; determine expectations in the physical, mental/intellectual, emotional, and social development of infants, toddlers, and preschoolers; describe ways to foster an infant's, toddler's, and preschooler's social, emotional, motor/physical, mental/intellectual, and language development; and identify procedures and precautions in providing a safe, healthful, comfortable environment for infants, toddlers, and preschoolers. Thirteen supplements contain information and activity sheets on the following: parenting attitudes, developmental expectations, what you can do for your child, safety hazards, and immunization. A bibliography contains 29 items. (YLB)
