This study aims to deepen our understanding of teaching, specifically the role of teachers' responsiveness in promoting equity in secondary science teaching. To build a conceptual argument--that teachers' responsiveness expands the opportunity to learn for students from historically marginalized communities--I explore one high school science…

This paper focuses on a historically understudied area in computing education: attending to students' *design thinking* in university-level introductory programming courses. I offer an account of one student--"Rebecca"--and her experiences and code from a second-semester course on programming concepts for engineers. Using data from both…

Heterogeneity is fundamental to learning and when leveraged in instruction, can benefit racially minoritized children. However, finding ways to leverage heterogeneity toward disciplinary teaching is a formidable challenge and teachers can benefit from targeted support to recognize heterogeneity in STEM, and its relationship to race and racism in…

Undergraduate mathematics education can be experienced in discouraging and marginalizing ways among Black students, Latin* students, and white women. Precalculus and calculus courses, in particular, operate as gatekeepers that contribute to racialized and gendered attrition in persistence with mathematics coursework and pursuits in STEM (science,…

This study examines the development of secondary preservice science teachers' (PSTs') sociopolitical understandings in the context of a yearlong, masters-level, justice-oriented teacher education program. It articulates a theoretical perspective regarding teachers' conceptions of the work-of-teaching in terms of pedagogical and disciplinary…

This study critically examines how the geopolitical configuration of identities, through the medium of the institutionalized label of "English language learners," can shape and constrain localized experiences for learners. An ethnographic video study was conducted in the context of a mathematics unit ("the transforming recess…

We examine a hypothesis implied by Steffe's constructivist model of children's numerical reasoning: a child's "spontaneous" additive strategy may relate to a foundational form of multiplicative reasoning, termed multiplicative double counting (mDC). To this end, we mix quantitative and qualitative analyses of 31 fourth graders' responses…

In this paper, we present data from two iterative teaching experiments involving students' constructions of four basic counting problems. The teaching experiments were designed to leverage the generalizing activities of relating and extending to provide students with opportunities to reflect on initial combinatorial activity when constructing…

Given growing interest in K-12 data and data science education, new approaches are needed to help students develop robust understandings of and familiarity with data. The model of the "quantified self"--in which data about one's own activities are collected and made into objects of study--provides inspiration for one such approach. By…

Creating learning environments that integrate arts, sciences, and computing in education can improve learning in these disciplines. In particular, transdisciplinary integrations of these disciplines can lead to expansive alterations or dissolutions of epistemological, ideological, and methodological boundaries. We wish to support teachers in the…

This study presents the results of a series of design experiments that aimed to engage twelve fourth-grade students in mathematical activity exploring the volume of right prisms and cylinders as a dynamic sweep of a surface through a height, an approach that is referred to as Dynamic Measurement for Volume (DYME-V). This article describes this…

This paper argues that the terms through which we interpret and work to develop expansive pedagogical practices are overly constrained by the binary of adult-centered versus child-centered education. Analyzing ethnographic data developed over three years in a making/tinkering afterschool program serving Black, Latinx, and Asian American students…

After three decades of scholarship describing why and how students ought to be taught to think historically, this study asks what happens when they are. Ten high school students from a school that incorporated historical thinking into all history coursework repeated the think-aloud task from Wineburg's 1991 study of the cognitive processes…

This article presents a formative intervention study, called "Learning Lab" that facilitated the collective design of a culturally responsive behavioral support system at an urban middle school in the United States. Learning Lab united parents, teachers, support staff, education leaders, and researchers, specifically those who have been…

Prior research shows that participation within communities of practice shapes children's development of repertoires of practice--ways of engaging in activities within a cultural community. Families are a privileged community for learning because of the extensive time spent together, the intimate nature of family relations, and the importance of…
