We investigate fifth-grade students' identity work and science learning at the margins of a science classroom. By "margins" we refer to activities unrelated to formal classroom instructional content and practices, and which unfold across many settings and contexts, including the classroom itself, but also multi-party, social group…

This article offers methodological insights and tools to those engaged in design-based research (DBR) seeking to advance equity-oriented learning and outcomes through co-design. We respond to recent scholarship that points to the inseparability between the assumptions we hold about society and those we hold about learning, and consider how such…

When teachers, researchers, and students describe productively responding to moments of failure in the learning process, what might this mean? Blending prior theoretical and empirical research on the relationship between failure and learning, and empirical results from four data sets that are part of a larger design-based research project, we…

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…

Learning in data-rich environments has been a focus of learning sciences research since the inception of the field, with increasing interest in the ways learners "narrate data." This article examines the narration of data from the perspective of "learning on the move," identifying mobilities of data, and of the narratives in…

In this study, we explore how cross-linguistic differences can contribute to children's scientific thinking. We compared first and third grade Chinese students' pre-instructional ideas of the earth expressed in clinical interviews with that of their English-speaking and Greek-speaking counterparts (as recorded in the literature). Inspired by a…

Ambitious teaching is a form of teaching that requires a high level of teacher responsiveness to what students do as they actively engage with the subject matter. Thus, a teacher enacting ambitious teaching is often confronted with uncertainties about how to advance students' learning while also building on students' contributions. In…
