Understanding how learning environments productively mobilize children's ideas as resources for participation in joint activity is an ongoing focus of research on classroom instruction. We investigated whole-class mathematics conversations in which multiple students participated in ways previous research suggests are consequential for learning. We…

This study explored expertise in searching for online information on a contentious historical and political question. Fact checkers, historians, and college students thought aloud while conducting online research on the question, "Did Margaret Sanger, the founder of Planned Parenthood, support euthanasia?" Analyses of screen recordings…

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…

This article explores how a curricular intervention that merges antiessentialist historical content and historical inquiry plays a role in how students complicate the narrative of racial progress. The 3-day curricular intervention centers on "Mendez v. Westminster," a case about 1940s Mexican American school segregation. The content and…

This article analyzes an episode of classroom mathematics activity mediated by graphing technology from 3 different theoretical perspectives. An important line of research in the learning sciences focuses on graphs as "inscriptions", foregrounding learners' interactions with and around the material properties of graphical displays.…

This article integrates an ecological approach and design-based research in computer science education research by following the simultaneous development of a computer programming environment and curriculum for elementary school age children over 2-1/2 years. We studied the alignment of the affordances provided by the programming environment and…

In this article, we provide a novel view of mathematics learning disability (MLD) by studying a student with an MLD (Dylan) who had compensated so effectively that she was able to major in statistics. We push back on the dominant deficit model used in studies of MLD, and consider issues of access and compensation from a Vygotskian theoretical…

Data visualizations are now commonplace in the public media. The ability to interpret and create such visualizations, as a form of data literacy, is increasingly important for democratic participation. Yet, the cross-disciplinary knowledge and skills needed to produce and use data visualizations and to develop data literacy are not fluidly…

We proposed and evaluated an instructional framework for increasing students' ability to understand and regulate collaborative interactions called Co-Regulated Collaborative Learning (CRCL). In this instantiation of CRCL, models of collaborative competence were articulated through a set of socio-metacognitive roles. Our population consisted of 28…
