In this article we examine the development, over 1 year, of mathematical discourse communities in 2 eighth-grade mathematics classes in a suburban public middle school. The curriculum topics included probability, functions, graphing, data analysis, and pre-algebra. The 50 students were heterogeneously placed; most were from upper-middle-class…

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…
