Chapter 6: Growth and Development of the School-Age Child

Growth and Development of the School-Age Child comprehensively details the growth and development of the school-age child (ages 6 to 12 years), a critical period marked by gradual physical maturation alongside rapid acceleration in social and cognitive complexity. Physiologically, children gain approximately 6 to 7 cm and 3 to 3.5 kg annually, with girls often surpassing boys in height and weight during the later preadolescent stage (prepubescence), a time characterized by the emergence of secondary sexual traits that can significantly impact self-esteem. While brain growth is nearly complete by age ten, important physical changes include increased bladder capacity, the refinement of gross and fine motor skills necessary for organized sports and dexterity, and the loss of deciduous teeth, making regular dental care vital to prevent caries, malocclusion, and bruxism. Erikson characterizes the psychosocial task as developing a sense of industry versus inferiority, where success in mastering skills and activities outside the home, often involving teachers and peers, fosters a crucial sense of competence and self-worth. Cognitively, children advance to Piaget's concrete operational stage, enabling them to think logically about tangible objects, understand complex classification, grasp the principle of conservation (that matter remains constant despite changes in form), and develop metalinguistic awareness, enjoying humor like jokes and riddles. Moral reasoning progresses through Kohlberg’s conventional stage, moving from following rules to gain approval as a "good child" to respecting established rules of society and incorporating the "golden rule". Social development is heavily influenced by peer relationships, which are essential for establishing independence and shaping self-perception, though family values generally remain the foundation during conflicts. Nurses play an essential role in promoting health and safety, particularly since unintentional injuries are the leading cause of death in this age group, requiring comprehensive education on proper car restraints, helmet use for cycling and sports, and fire/water safety. Health promotion emphasizes nutritional guidance to combat rising rates of childhood obesity by encouraging appropriate caloric intake, managing portion sizes, and reducing sedentary behaviors like excessive screen time. The chapter also addresses common developmental concerns such as school refusal, the safety of latchkey children, and managing problematic behaviors like lying, stealing, cheating, and bullying (including cyberbullying), emphasizing the importance of parental role modeling and consistent, supportive discipline.
