Some teacher educators are proposing and practicing "case teaching." Those proposals and practices center on cases: narratives and descriptions of teaching that were constructed specifically for use in a teacher's education. Typically, teacher educators or teachers write the cases, but sometimes they choose and adapt material from other literature such as research case studies. Occasionally, they ask student teachers to write cases that organize and reflect on their own experience, apply educational theory to those experiences, or both.Doyle (1990a) contrasts case methods both with propositions about teaching and learning and with opportunities to teach in laboratory or field settings, thus suggesting that case teaching is focused more on particular situations than on general principles, findings, and rules, but also that the student's encounter with those situations typically is vicarious rather than direct. Although the encounter with cases is an indirect contact with teaching, it is not passive. Work with a case typically is intended to draw the student into the situations, problems, and roles that are represented in the case. An engaging discussion of a case can become like role playing or simulations, which sometimes are used to explore cases.In this chapter, we aim to survey the variety of cases, descriptions of case teaching, and arguments being made about case teaching in teacher education. At present, there is little research or theory specific to case teaching in teacher education; therefore, we will join the proponents and practitioners in looking at other literature that raises issues, questions, and possibilities. We will begin with a sampling of cases and arguments about them, then discuss cases as part of the teacher education curric-We are grateful to Mary Kennedy, Judith Kleinfeld, and Lee Shulman for their detailed commentary and many helpful suggestions on an earlier draft of this essay.
