The High/Scope Institute for IDEAS began in the early 1960s as a summer camp program and is now a dynamic learning program for teens that emphasizes working with them in an environment which supports emotional, social, and intellectual development. The High/Scope model for adolescent programs is based on the following principles: (1) adolescents need a safe psychological environment; (2) adolescents need a chance to make new beginnings; (3) adolescents need program activities designed to relate to their developmental stages; and (4) adolescents need to be given genuine responsibility. This book describes the High/Scope model in the following chapters: (1) "The High/Scope Institute for IDEAS Program--The Beginnings and Evolution," giving the history of the institute along with its philosophy and long- and short-term benefits; (2) "Who Are the Participants and What Do They Need?" focusing on developmental characteristics, tasks and developmental gains, and meeting adolescent needs; (3) "Creating a Supportive Context for Learning," outlining the program schedule and daily routine and also discussing psychological and physical safety, expectations, and adult participation; (4) "The Educational Approach," dealing with the five essential components of choice, active learning, plan-do-review, cooperative learning, and leadership development; (5) "Learning Potential Within the Institute Setting"; and (6) "Lessons Learned: Beyond the High/Scope Institute Model."
