This document, third in a series by the Study Commission on Undergraduate Education and the Education of Teachers, is to be used in preparing the American educational community and specifically, institutions and people working at the reform of the undergraduate education of teachers, to think through the issues and plan reform programs envisaged by the Undergraduate Preparation of Educational Personnel (UPEP) amendment contained in the Higher Education Act of 1972. The book is a report of a conference held to plan the work of the Learning Contexts committee. The function of the meeting was to propose mechanisms and models through which significant educational reform might be realized and to examine the usefulness of previous efforts in higher education and at the elementary and secondary levels. The book contains three sections: 1) a section of essays on education and the community-building process which sets down the background of the thinking of the participants in the conference; 2) a value statement developed by the Study Commission as part of the UPEP program; and 3) an excerpted transcript of the proceedings of the conference, including a general session and committees on action models, neighborhoods, and levers and mechanisms.
