This document describes a variety of curriculum integration options ranging from concurrent teaching of related subjects to fusion of curriculum focus to residential study focusing on daily living; from 2-week units to year-long courses. Suggestions are offered for choosing proper criteria for successful curriculum integration, dealing with the attitudes of key individuals and groups; and establishing validity. A step-by-step approach to integration is presented, proceeding from selection of an organizing center to a scope and sequence of guiding questions to a matrix of activities for developing integrated units of study. A distinction is made between curriculum-content and metacurriculum--those learning skills helpful in acquiring the curriculum content being taught and in developing the capacity to think and learn independently. The book illuminates the value of higher-order thinking and learning skills and provides a vehicle for their integration into curriculum. (JD)
