Intensive education is an alternative educational approach in which students study one or two subjects a day for a concentrated number of weeks. This report considers whether intensive study is a valid alternative to the traditional class schedule and discusses the strengths, values, and problems of intensive education. Data sources for the report include 1) a selective review of the history and literature of intensive education; 2) interviews with teachers, administrators, and students; 3) site visits to nine intensive education programs; 4) observation of 12 intensive education classes; and 5) a survey of administrators of 34 secondary school intensive education programs. Section 1 presents a historical review of different studies and approaches involving time as a dimension of learning. Section 2 discusses examples of various intensive education programs. Section 3 examines the effects of intensive education on student learning, teacher roles and methods, and student-teacher relationships. Section 4 discusses the implementation of intensive education programs. The appendix describes 20 existing programs that incorporate some form of intensive study at the secondary level. (Author/JG)
