The document outlines the 4 main steps in curriculum development according to Ralph Tyler: 1) Formation of educational objectives, 2) Selection of learning experiences, 3) Organization of learning experiences, and 4) Evaluation of the curriculum. Educational objectives are statements describing desired changes in student behavior. Learning experiences are deliberately planned situations where students actively participate and change behaviors. Organizing learning experiences considers continuity, sequence, balance, and integration. Curriculum evaluation assesses the philosophy, goals, objectives, content, teaching methods, and relationship to extracurricular activities.
