In this report of a working conference, experts in the teacher education field considered the adequacy of current research on teaching practices and obstacles in the implementation of changes based on research findings. In "How Useful Are the Findings from the Research on Teaching," Jane A. Stallings discussed findings from research on teaching which appear most amenable to translation into staff development activities. Richard C. Williams, in "Changing Teacher Behaviors: From Symbolism to Reality," presented an analysis of school contexts from an organizational perspective, and of the way these contexts impinge upon changing teacher practice. In "An Expanded View of the Student Outcomes That Are Built or Restrained by Teaching Processes and Structures," Beatrice A. Ward considered a variety of student outcome variables which might be used to assess teaching effectiveness. Sara Edwards asked conference participants to respond to a series of questions about research and teacher education for "Recommendations for Study on Changing Teacher Practice." A "Summary of the Discussions" at the working conference, prepared by Heather Carter, discussed issues surrounding use of research as a basis for change in teacher practice, the current knowledge base to address these issues, and the needed knowledge base to address these issues. A list of the conference participants is appended. (JD)
