This publication is designed to serve 3 purposes: (1) It is a report of the 1966 Summer Workshop-Symposium on "School-College Partnerships in Teacher Education," cosponsored by the publishers, (2) It presents additional thinking not included in that program or which has come to light since, and (3) It serves as a follow-up to 1964 and 1965 studies as third in a series devoted to helping those interested in teacher education to stay abreast of changes and to be prepared to exercise enlightened leadership. Most of the 34 contributors are university-based administrators of teacher education programs. Section 1 provides brief reflections on the workshop-symposium, and Section 2 presents much of the conference content: a chapter on promises and pitfalls in the trend toward collaboration; descriptions and analyses of emerging partnerships in teacher education; a review of group discussions at the conference; and elaborations on 7 issues and problems in cooperative venturing. Section 3 focuses on emerging administrative and regulatory developments in collaborative enterprises. Section 4 deals with the foundations for partnership in the philosophical bases of teacher education. Various innovative procedures and practices in supervision, such as microteaching, simulation training, and pre-student teaching laboratories, are discussed in the 12 parts of Section 5. A final section offers "A Look at the Future." (JS)
