This document discusses the historical development of curriculum theory from the 1880s to present day. It covers several approaches to curriculum development including: 1. The traditionalist approach advocated by theorists like Ralph Tyler which focused on practical, local problem solving. 2. The conceptual-empiricist approach which emphasized empirical research and "teacher-proof" curriculum developed by experts. 3. The reconceptualist view which criticized previous approaches for focusing too much on schools and not questioning the underlying assumptions of curriculum. Reconceptualists called for a complete rethinking of the purpose of education.
