This article reviews the case method from an historical perspective and explores why and how "decision" cases might be used by teacher educators in the professional preparation of teachers as reflective ESOL specialists. It is argued that the case method can sharpen the critical thinking, analytical, and communication skills ofboth novice and experienced teachers and help ready them for the complex challenges they could face in the world of professional practice. Enthusiasm for this methodology, however, is tempered with words of caution about the difficulties involved in implementing case-based learning in teacher education programs. Guidelines for selecting and using"decision" cases are provided and recommendations are made for future developments in case-based teaching and learning in TESOL. Three appendixes include sources for teaching cases and details about a working conference for case facilitators and writers.Teaching cases have long been a cornerstone of professional preparation in schools of law, business, and medicine. Teacher educators have also been exploring their value in the preparation of teachers, although relatively few TESOL specialists have ventured into case-based teaching, writing, and research Doyle, 1990;Jackson, 1996aJackson, , 1996bKleinfeld, 1992;Merseth, 1991a;). This article is based on the belief that TESOL teacher education programs can benefit from what colleagues in other disciplines have discovered and published about case writing and teaching. The case method, I argue, is particularly suited to the analysis of the complex issues and situations that ESOL teachers routinely face. Thus this article briefly describes the principles, benefits, and challenges involved in implementing case-based learning in programs that are designed to prepare teachers as reflective ESOL specialists.
Historical Roots of the Case MethodCase method teaching has for over 100 years been incorporated into professional preparation programs as one means of narrowing the gap between theoretical knowledge and practice. In 1870 the case method was introduced in the Harvard University Law School where the objective of the method was to teach legal principles (Merseth, 1991b). Law instructors questioned stu-TESL CANADA JOURNAULA REVUE TESL DU CANADA VOL. 14, NO.2, SPRING 1997 dents in a way so as to guide them to the predetermined "right" answers or decisions in actual court cases. By 1915 this variation of the case method was the primary mode of instruction in most of the well-known law schools in the United States (Culbertson, Jacobson, & Reller, 1960).In the 1920s the case method became popular in the Harvard Business School and then spread to business schools across North America and beyond (Knirk, 1991;Osigweh, 1989). Instructors in this field have traditionally used cases quite differently from their colleagues in law. Business cases are primarily used to teach students how to analyze problems and to determine and evaluate appropriate courses of action (Cooper, 1995;Hammond, 1980;Kleinfeld, 1990). The cas...
