One of the foremost scholars of interdisciplinary teaching techniques is James Beane, who advocates for curriculum integration, which is curriculum that is collaboratively designed around important issues. It has four major components: the integration of experiences, social integration, the integration of knowledge, and integration as a curriculum design. It differs from other types of interdisciplinary teaching in that it begins with a central theme that emerges from questions or social concerns students have, without regard to subject delineations (Beane, 1997).
