Early adolescent development involves significant physical, cognitive, and social changes between the ages of 10-14. Physically, students begin puberty and experience changes in hormones and appearance. Cognitively, they develop more advanced thinking skills but still have short attention spans. Socially, students seek independence but remain influenced by peers and desire approval, while developing their identities. The document provides strategies for teachers, such as active learning experiences, incorporating student interests, and opportunities for leadership, to effectively support students through these developmental changes.
