The case method is a popular teaching tool that can be applied to training for diversity and particularly the preparation of general education teachers for the inclusion of diverse learners in their classrooms. Case-based methodology teacher training activities focus on actual classroom experiences and prompt reflection and personal involvement. A study was done to validate these techniques with 56 student teachers in 2 groups. One group used a problem-solving strategy to analyze differing case features. This strategy group did 40 percent better on case problem-solving than those solving case problems without the strategy. A comparison was made of the identification of features with problem-solving scores to determine if the strategy was the determining factor, and a high positive correlation was found. The case method of teaching was found to promote classroom problem-solving when cases are systematically varied and when student teachers are given a strategy that guides transfer of learning from case to case. This demonstrates that student teachers can be trained to transfer learning from one teaching problem to another involving a diverse population of students. (Contains 8 references.) (JLS)
