The Construction Of Mathematical Reasoning As A Pedagogical Object, Nick Pratt, Julie Alderton

School of Law, Humanities and Social Sciences

This paper explores how policy aims in mathematics curricula appear in classrooms and, crucially, how the resulting pedagogical practice affects the nature of mathematics itself. Whereas there have been many studies of policy and its relationship with teachers’ practices, few have examined epistemological effects; what mathematics becomes as it is translated from an educational, and political, intention into classroom activity. To focus the study, we examine reasoning as a central idea in mathematics, in the English primary (5-11 years) context. Rather than concentrating on best practice, as an objective account of how to teach reasoning, we adopt a post-structural theoretical …

“If I Ruled The World”: Deploying Spatial Imaginaries For Examining Anti-Blackness And Space In Precollege Engineering Education, Christopher Wright, Monet V. F. Harbison

Journal of Pre-College Engineering Education Research (J-PEER)

Engineering’s systemic exclusion of Black people has been a decades-long inquiry. While critical race theory and community cultural wealth have been utilized to examine anti-Blackness in precollege engineering education, critical geographies have been underutilized. This essay contends that the deployment of a spatial imaginaries lens could be used to expand understandings of the spatial imaginary of anti-Blackness in the discipline. Using historical and contemporary data from an engineering high school as well as nonpositivist ways of knowing, the essay contends that examining spatial realities and underpinnings are opportune provocations for redefining purposes, assumptions, and values in precollege engineering education.
