This short volume, written to help educational institutions engage in curriculum building, called for the application of four corresponding principles in the development of any curriculum: defining goals, establishing corresponding learning experiences, organizing learning experiences to have a cumulative effect, and evaluating outcomes. Tyler’s principles were the accepted approach to curriculum development for almost 30 years, and they guide the essential questions of curriculum development today, though they now are applied to newer ideas and considerations that extend or reinterpret his principles.
