Purpose: The purpose of this paper is to present insights from the implementation of a dialogic social studies curriculum and its potential to support diverse learners. Policymakers and educators must attend to the learning needs of diverse/minoritized (Note: In this paper, the authors use minoritized and diverse interchangeably) students who have been marginalized in public education. A critical goal is to close racial, ethnic and socioeconomic achievement gaps by increasing, for example, students' engagement with curriculum and instruction. In this paper, the authors bridge research on dialogic instruction and culturally relevant and responsive education with the goal of informing curricular design and instructional practice. Design/methodology/approach: This conceptual paper discusses the utility of dialogic instruction in improving learning outcomes for minoritized student populations. While some researchers have examined the positive effects of dialogic instruction on underperforming students (e.g. Murphy et al., 2009; Pillinger and Vardy, 2022), few scholars have examined dialogic instruction through a culturally relevant and responsive lens. The authors argue that the application of this critical lens may improve learning outcomes for diverse learners who have been marginalized in public education systems. Findings: The authors present illustrative vignettes and insights from a pilot study of a novel social studies curriculum. This curriculum applies a social justice lens by guiding students in the exploration of complex social issues that affect them. Given the diversity of their collaborating teachers' classrooms (55% are racially minoritized students), the authors applied principles of culturally relevant and responsive education (e.g. Ford, 2010; Gay, 2000; Ladson-Billings, 1995) when designing and piloting the curriculum. Prior personal and professional experiences by the first author point to the potential of dialogic instruction to meaningfully support minoritized students' learning. Originality/value: This paper builds on two bodies of literature -- dialogic instruction and culturally relevant and responsive education -- to identify how an innovative social studies curriculum may improve learning for diverse student populations. It calls for the advancement of a research agenda that applies a culturally relevant and responsive lens to inform instructional practice. The authors begin this discussion with two vignettes.
