    Social justice mathematical modeling is powerful in helping teachers build awareness of social issues, critique existing systems, and engage in rich mathematical reasoning. In this article, we document a task in which 28 preservice teachers (PSTs) explored if teacher pay is fair and how to define “fair” mathematically. Through qualitative analysis of PSTs’ reflections, we studied the effectiveness of the task through the lens of critical consciousness. Twenty-six of the participants reported developing social and mathematical agency with respect to the task. Because the task related to PSTs’ lived experiences, it allowed them to examine their assumptions about teacher pay, empowered them to use mathematics to explore different perspectives, and helped them envision ways they could enact change.

    A growing consensus holds that preservice K–8 teachers (PSTs) need to experience the modeling process as learners to understand it and envision teaching modeling in their future classrooms. We examine this recommendation by exploring how PSTs construct models and how collaborative learning practices influence them in revising and refining their models. We also explore their reflections on modeling as a pedagogical experience. We introduce Modeling Decision Maps as a tool to examine how PSTs construct and refine mathematical models, and we draw on reflective journal entries to capture PSTs’ perspectives on the process. Our findings indicate that realistic modeling tasks provide opportunities to foster PSTs’ understanding of modeling, grow their mathematical modeling skills, and attune them to important pedagogical practices.
