The chapter discusses three models for curriculum development: the Tyler Model, the Taba Model, and the Oliva Model. The Tyler Model is a deductive model that begins with examining societal needs and ends with specifying instructional objectives. The Taba Model uses an inductive approach, starting with creating teaching units and building to a overall design. The Oliva Model is also deductive and provides a process for a school faculty to develop the entire curriculum based on the needs of their students. The models illustrate different approaches to curriculum planning but should be adapted based on the unique needs and context of each situation.
