Recent literature indicates that supervision at the secondary level in physical education has had little significant impact on the overall experience of a student teacher. Two factors contributing to these results have been the type of setting and the nontraining of the cooperating teacher. Recent studies have also shown through objective data that the effectiveness of the student teacher could be changed through various supervisory techniques. Thus, by incorporating the use of objective data, a trained supervisor could alter the experience of a student teacher towards effectiveness. Research in physical education teacher education has also supported the use of qualitative methods to enhance a student teaching experience. Therefore, a field study was conducted in which a trained public school cooperating teacher recorded the overall experience of supervising a student teacher, incorporated various observation methods, and used the data collected to positively change teacher effectiveness. Through the use of both quantitative and ethnographic techniques, the final result of this study could contribute to the current research on the supervision of student teachers and effective teaching.
