The document discusses the structure and components of curriculum development. It identifies 5 key components: 1) The Learner and Society, focusing on individual and social needs, 2) Aims and Objectives which reflect needs and serve as a basis for content, 3) Content/Subject Matter which is organized to achieve aims and presented through textbooks, 4) Teaching Methodology which results in learning outcomes through techniques chosen by teachers, and 5) Evaluation which measures learning outcomes and provides feedback. Teachers play an essential role by providing insights during planning, implementing the written curriculum, and assessing/modifying it based on their knowledge of students' needs.
