This model pre-student teaching laboratory program is a modification of the traditional field experience program for secondary teacher education students. Rather than being assigned to individual teachers in a laboratory school, students are organized into cells for exposure to selected professionally oriented experiences in different types of schools. Each cell consists of about 20 students, a faculty member from the area of secondary education who serves as coordinator, five secondary school teachers from the laboratory school and teachers from other cooperating schools. The program is divided into cycles which include preparation, field experience, and follow-up sessions. Evaluation indicates that program participants profited considerably in development of their perceptions about students, teachers, classrooms, methods, and themselves and were able to apply these perceptions in the student teaching which followed. A followup study for further evaluation has been designed. Significant aspects of the program are being incorporated into the regular secondary school teacher preparation program. (Two appendixes contain a list of the personal and professional areas in which perceptual development is anticipated and a list of behavioral objectives.) (RT)
