This six-chapter monograph presents a model for student development which is designed to unify the diverse purposes of education. After Chapter I reviews recent criticism of education, it goes on to identify problems in the performance of our educational system and to propose that a student development perspective on education provides a framework for individualizing education. In addition to tracing the origins of student development, Chapter II delineates the student development education (SDE) model, which involves administrators, teachers, and counselors in a competency-based process of goal setting; assessment; use of change strategies in instruction, consultation, and milieu management; and evaluation. Chapter III provides theoretical support for this model in a review of the literature on developmental learning and moral, personal-social, physical, and individual development. Chapter IV discusses an attempt to implement the SDE model in the Police Science program at a two-year college and reviews the problems, challenges, and outcomes of this effort. Chapter V presents the results of a nationwide study of the current use of student development in colleges and universities. Chapter VI concludes with a summary of the problems and issues of evaluation. The monograph is appended by the questionnaire used in the student development survey, a history of the development of competencies for a Black History course, and a description of the SDE curriculum at El Centro College.
