Teacher Learning About Mathematical Reasoning: An Instructional Model
Page: 1516
First, I describe an instructional model for Teacher Learning about Mathematical Reasoning (TLMR), designed for pre-service (PSTs) and in-service teachers (ISTs) to: (a) build knowledge of the various forms of mathematical reasoning that students naturally make use of in their justifying solutions to problems, (b) attend to the development of students’ mathematical reasoning from studying videos and student written work, and (c) learn about the conditions and teacher moves that facilitate student justifications of problem solutions. Second, I provide a detailed description of activities from a representative cycle of the TLMR model. Finally, I report briefly on preliminary results indicating teacher growth in identifying and recognizing student reasoning for PSTs and ISTs who underwent the TLMR model compared to a comparison group.
