A large-scale descriptive study of preservice clinical teacher education was conducted in 2 sites, involving 88 cooperating teachers, 93 student teachers, and 17 university supervisors. This report discusses the perspectives of the participants. Student teachers, cooperating teachers, and university supervisors are discussed in terms of personality characteristics, cognitive characteristics, and professional orientation. Changes in these characteristics and orientations are described, and outcomes of the experience are examined. Relationships among characteristics, change, and outcomes are noted. Results indicated that each of the participants experienced some change over the course of student teaching. Student teachers showed the most change, followed by the cooperating teachers, and then the university supervisors. All experienced some change in terms of their concerns; however, most of the change showed a decrease in concerns. Appendixes include samples of measurement instruments used in the study and tables displaying the data collected. (JD)
