This book presents nine studies conducted by teacher researchers who explore the oral and written discourse of learning communities--communities of students, communities of teachers, and communities in which students and teachers learn together. The studies focus on journal writing, conversation, story telling, geometry, computer technology, and teacher collaboration. After an introduction ("Teachers as Researchers: Past and Present" by Janice Lake Betts), chapters in the book are (1) "Reliving the Learning: Learning from Classroom Talk and Texts" (Leslie Patterson); (2) "Allowing Space for Not Knowing: A Dialogue about Teachers' Journals" (Marne B. Isakson and David D. Williams); (3) "Building a Reflecting Classroom" (Franca Fedele); (4) "Students Telling Stories: Inquiry into the Process of Learning Stories" (Judy Caulfield); (5) "A Language Experience Approach to Elementary Geometry" (Monica McGlynn-Stewart); (6) "Technology and Reflection: Knowing Our World and Our Work" (Jeannine St. Pierre-Hirtle); (7) "Collaboration, Community, and Communication: Models of Discourse for Teacher Research" (Zoe Donoahue); (8) "Collaborative Inquiry: The Practice of Professional Development" (Flavia Churchill); and (9) "Wild Dreams and Sober Cautions: The Future of Teacher Research" (Marian M. Mohr). Contains author and subject indexes. (RS)
