From some 700 books and articles on the professional education of teachers, most of them published from July 1966 through June 1967, 350 were selected for inclusion in this annotated bibliography. Entries were selected for representative quality and significance. The introduction lists 12 observations regarding trends in the field and notes the bases for a 15-category classification. Short paragraph annotations describe the contents of each entry. Though emphasis is on laboratory experiences, references are also included on college teaching in professional education courses; team teaching and paraprofessionals; students in teaching; teacher recruitment; certification, and accreditation; and studies of teaching. The largest section contains 65 entries on conditions and developments in teacher education curriculums; another 18 deal with the content and organization of the professional component in teacher education. There are separate sections on specialization in teacher education programs and on teachers for urban and depressed areas. Sections dealing with laboratory experiences include school-university responsibility for the professional laboratory, supervision in the professional laboratory, student teaching, and interns and beginning teachers. Other categories are teacher education and technology, and recent research reports. (JS)
