ABSTRACT
Ralph Tyler had a major impact upon curriculum over his long life. Tyler describes in his book a number of principles that have come to be known as the 'Tyler Rationale'. Tyler's model states how to build a curriculum. He argues that there are really four principles or 'big questions' that curriculum makers have to ask. These questions are concerned with selecting objectives, selecting learning No single source of information is adequate to provide a basis for wise and comprehensive decisions about the objectives of the school. Tyler's book provides no way of deciding which educational philosophy should be used. In one sense this explains the popularity of Tyler's approach because it caters for a diversity of value stances. Tyler makes clear his belief that learning will be most efficient only if it is properly organized. Specifically, he suggests that each learning experience should be built upon earlier ones and should be reinforced by activities in other subjects.
