The preservice, inservice, field-based teacher education program of Ohio State University is designed as an integration of theory and practice involving preservice students with local children during all four years of their career preparation, under the close observation of university instructors. The inservice portion of the program was developed in part to counteract the uncritical identification of student teachers with their cooperating teachers' methodologies and in part to expose inservice teachers to new methods and theories. Techniques used for these purposes included freshman practical experience in supervision coupled with inservice teacher participation in field-based methods courses, summer institutes, workshops, tours, debates, etc. Evaluation of inservice teachers' performances in these programs are used to identify good teachers and enlist their services for cooperating teacher positions. The core of the program is a series of preservice professional growth experiences, divided into three phases: (1) a freshman year concentration, "Focusing on Self and Choice of Career," concerned with developing, through field experiences, an adequate picture of self and role, testing the role concept against reality, and modifying the concept to satisfy the student and benefit society; (2) a sophomore year program, "Exploring the School within the Context of Community," concerned with identifying the school microcosm and school-community relationships, educational psychology, and a possible future synthesis seminar; (3) methods course blocks in various curricular groupings (Introductory courses; Language Arts; Math, Social Sciences and Science; Fine Arts; Integrated Interdisciplinary Block; Student Teaching Experience) designed to allow students an opportunity to work at one school for a considerable portion of each school day over a significant period of time.
