In this exploratory study, teachers' use of standards-based, discourse practices and their students' mathematics learning in inclusive elementary mathematics classrooms were examined. Two beginning teachers (one third-grade teacher, one fourth-grade teacher) and six students identified with disabilities or as low performing in mathematics participated in this study (three students from each classroom). Six classroom observations of teachers took place over 4 months focusing on a subset of indicators associated with Walshaw and Anthony's framework of mathematics classroom discourse practices. Follow-up interviews were also conducted. Curriculum-based and state-accountability measures were collected on the six target students in these settings. Different patterns of student performance emerged across the two classrooms in which teachers were observed using different types and degrees of standards-based discourse practices during mathematics lessons. Findings suggest indicators of effective mathematics teaching in inclusive general education classrooms to be validated by future research efforts. (Contains 6 tables and 2 figures.)
