Despite longstanding criticisms of teacher education, the weight of substantial evidence indicates that teachers who have had more preparation for teaching are more confident and successful with students than those who have had little or none. Recent evidence also indicates that reforms of teacher education creating more tightly integrated programs with extended clinical preparation interwoven with coursework on learning and teaching produce teachers who are both more effective and more likely to enter and stay in teaching. An important contribution of teacher education is its development of teachers’ abilities to examine teaching from the perspective of learners who bring diverse experiences and frames of reference to the classroom.
