The document discusses the historical perspectives of curriculum development. It defines curriculum as what is taught in school, a sequence of courses, a set of subjects, performance objectives, and content. Curriculum development has been motivated by religion, politics, utilitarianism, mass education, and excellence. Traditional curriculum viewed it as rigid body of subjects prepared by teachers for students to learn from. It aimed to fit learners into the existing social order. Modern curriculum considers the total experiences of the learner and is learner-centered and flexible based on interests. It uses life experiences to prepare students for social life and values constant revision and experimental techniques.
