Educators have recently stressed the importance of teacher/researchers investigating life in the classroom. Collaborative studies conducted between a student teacher and a cooperating teacher can provide a productive relationship from which both can learn a great deal about teaching, learning, and research. The collaborative study discussed in this document provided a structure for the cooperating teacher to observe and evaluate instruction, and for both teachers to reflect on the relative effectiveness of different teaching methods. Such experience can help make student teaching more fruitful and help develop positive attitudes towards research and reflection for career-long benefits. (Author)
