The document discusses several approaches to curriculum: 1) The behavioral approach uses blueprints with goals, objectives, and activities matched to learning objectives and measures change in behavior. 2) The managerial approach views the principal as the curriculum leader who sets policies, plans curriculum changes, and administers resources. 3) The system approach represents the school as an organizational chart showing line and staff relationships and how decisions are made, giving equal importance to administration, counseling, curriculum, instruction, and evaluation. 4) The humanistic approach considers both the formal and informal curriculum and believes the total development of the individual learner should be the prime focus of curriculum.
