This paper reports on a teaching innovation where groups of experienced and novice teachers collaborated in analyzing case studies involving the education of students with special learning needs. The teachers collaborated in an asynchronous computer conferencing system (Web Knowledge Forum). All participants were enrolled in special education graduate courses taught by the authors. The authors discuss the use of case studies in teacher education, collaboration between novice and expert teachers, and highlight some of the demands of computer conferencing particularly in relation to the loss of face-to-face interactions and the interpretive demands of electronic communication.
