Mapping Mathematics in Classroom Discourse
Beth A. Herbel-Eisenmann and Samuel Otten
This article offers a particular analytic method from systemic functional linguistics, thematic analysis, which reveals the mathematical meaning potentials construed in discourse. Analyses of two middle school classroom excerpts focusing on area—one that derives triangle area formulas from the rectangle area formula and another that connects parallelogram and rectangular area—are used to delineate the method. Descriptions of similarities and differences in the classroom discourse highlight how, in each classroom, mathematical terms such as base and height were used in semantically related, but distinct, ways.
