It defines curriculum development as selecting, organizing, executing, and evaluating learning experiences based on learner needs, abilities, and interests as well as societal needs. It outlines four philosophies that guide curriculum - perennialism, essentialism, progressivism, and reconstructivism - and compares their aims, the role of education, and focus in curriculum.
