Many educators suggest that deteriorating academic quality in schools can be addressed with the help of an approach to curriculum development called "curriculum integration," which presents a holistic view of knowledge to learners. One reason among many to move from subject-focused curriculum to curriculum integration is that the former fails to provide learners with the intellectual skills needed in a competitive society. Other arguments stem from the ability of curriculum integration to actively involve students in their own education. Traditionally, integrated approaches to curriculum design have been associated with "intermingling" of disciplines such as thinking, reasoning, and problem-solving capabilities. Operational schemes of curriculum integration specify the degree of integration and depend upon the content, processes, and skills involved in learning. Curriculum integration is not a random combination of disciplines and should be approached with a systematic, conscious effort that makes relationships among disciplines explicit.
