This paper attempts to engage the field in a discussion about what mathematics is needed for students to engage in society, especially with an increase in technology and digitalization. In this respect, mathematics holds a special place in STEM as machines do most of the calculations that students are taught in K-12. We raise questions about what mathematical proficiency means in today’s world and what shifts need to be made in both content and pedagogy to prepare students for 21st Century Skills and mathematical reasoning.

In this article we analyze the current state of the didactics of mathematics in the U.S. as it relates to research on equity. The sociopolitical turn in U.S. mathematics education resulted in a push for critical mathematics pedagogies (CMPs) in which predominantly marginalized populations of students explore social injustices through mathematics. We argue that mathematics education for equity must access broader populations of students and develop students’ ethical reasoning skills to build an ethical and equitable future. To address didactical limitations in U.S. mathematics education, we introduce the Ethical Reasoning in Mathematics Framework (ERiM) as a tool to analyze high school students’ ethical reasoning in real-world mathematics tasks. Using data from the initial phase of a Design Research project with students of privilege, we show how the ERiM Framework can be used to design lessons that elicit students’ critical math consciousness (CMC). We end the article with design implications and recommendations for future research on the didactics of equitable mathematics.

Recent events reveal the impact of systemic inequities on marginalized communities and highlight the importance of critical frameworks in science teacher education. Education theorists and research suggest that lack of sociopolitical, or critical, consciousness among teachers limits their ability to engage students in culturally relevant teaching and learning; provoking critical consciousness among white educators is an especially daunting task. Research is needed to uncover how science teacher educators might support the development of critical consciousness among practicing science teachers. In this article, we present findings from a study situated within a larger Design-based Research project to test and revise an instructional sequence grounded in science content, collaborative inquiry, and critical place-based pedagogies. This analysis of how participants’ collective awareness developed over the course of a four-day Professional Development workshop offers insight into how innovative in-service science teacher education might be employed to support practitioners’ understanding of oppressive systems including those inherent in the discipline of science. Findings suggest that the incorporation of collaborative inquiry as a design heuristic supported teachers’ emerging understanding of the role inequitable systems play in disparate health outcomes. In addition, interrogating race and racism in the context of science challenged deficit frameworks and prompted some participants to acknowledge the limitations of their own lived experiences in comparison with those of their students. Implications include a new model for professional development to support practicing teachers’ moves toward justice-oriented science teaching and learning.
