Over the years, educational psychology has been a part of teacher preparation, moving from a centerpiece in many programs, through periods when it was deemed irrelevant by some, to current concerns about its role in the reforming of teacher education and teaching. Today, psychological knowledge is used to ground reforms in teaching and schooling, particularly the call for teaching for understanding. Current standards for teacher certifications and licensure and suggestions for reform in teacher education assume that teachers will have a deep and generative understanding of learning, development, motivation, and individual differences. This article explores several themes that recur in the writing on reforms and teacher standards: the need to place learning at the center of teaching, the call for integrated studies, and the value of collaboration with the public schools. These themes have both positive and negative implications for the role of educational psychology in teacher education.
