This document discusses curriculum development and different approaches to curriculum. It defines curriculum development as the process of selecting, organizing, executing, and evaluating learning experiences based on learner needs, abilities, interests, and the school/community environment. It provides an example of how modern language classrooms often use an eclectic approach drawing from various methods. An approach represents a view of language and learning, which gives rise to classroom methods and techniques. The document outlines four common curriculum approaches: the behavioral approach which studies observable behavior and environment; the managerial approach which views the school as a social system; the systems approach which is a problem-solving process; and the humanistic approach which places the learner at the center.
