This document discusses the major foundations of curriculum: philosophical, psychological, historical, and social. It provides examples of influential curriculum theorists like Franklin Bobbitt, Werret Charters, Harold Rugg, and William Kilpatrick who helped establish the historical foundations. The psychological foundations are based on behaviorist, cognitive, and humanistic learning theories. Finally, the social foundations recognize that schools exist within a social context and curriculum aims to understand globalization and changes in society.
