Background: The transition to technology-mediated remote schooling during the COVID-19 pandemic represented a drastic shift in educational technologies' function in K-12 settings. This theoretical paper sought to: (1) identify key developments in technology-use during the pandemic; (2) situate current events within the Learning Sciences' evolving…

Background: Teachers need to make sense of curricular materials and design instruction to ensure students will be positioned to pursue their own arc of inquiry in curriculum enactment. Whole-group discussions are crucial opportunities for curricular sensemaking, yet planning and enactment can be challenging. Methods: We used a single, revelatory…

Background: Social movement scholarship tends to focus on macro-level processes of movement emergence, overlooking the day-to-day groundwork of marginalized social movement actors who contribute to and sustain large-scale action. Contributing to this gap in literature, we develop the construct of "pedagogies of organizing" to illuminate…

This article uses a variety of principles of cultural-historical activity theory to extend Herbert Simon's (1996) insight into the inherent linkage between the creation of artifacts and design. We argue that design research must grapple with the doubly artificial, as the classrooms in which many educational designs are implemented are themselves…

The design research methodology as it has currently developed centers on the creation of "existence proofs," an important first step. What is needed then are the next steps of expanding the methodology to address the design problems of practical implementation prior to the steps involved in scaling up these designs. This article contributes to…

Learning progressions (LPs) are theoretical models of how learners develop expertise in a domain over extended periods of time. Recent policy reports have touted LPs as a promising approach to aligning standards, curriculum, and assessment. However, the scholarship on LPs is relatively sparse, and the jury is still out on the theoretical and…

Many types of learning require the mapping of information across situations. The proposed organizational framework extends the cognitive study of mappings across problems to include mappings across representations, solutions, and sociocultural contexts. I apply one-to-one, one-to-many, and partial mappings to analyze representative cases that…

Some intensive quantities, such as slope, velocity, or likelihood, are perceptually privileged in the sense that they are experienced as holistic, irreducible sensations. However, the formal expression of these quantities uses "a/b" analytic metrics; for example, the slope of a line is the quotient of its rise and run. Thus, whereas students'…

Evaluating the impact of instructional innovations and coordinating instruction, assessment, and testing present complex tensions. Many evaluation and coordination efforts aim to address these tensions by using the coherence provided by modern cognitive science perspectives on domain-specific learning. This paper introduces an alternative…

This study investigates the ongoing debate in the conceptual change literature between unitary and elemental perspectives on students' knowledge structure coherence. More specifically, the current study explores two potential explanations for the conflicting results reported by Ioannides and Vosniadou (2002)and diSessa, Gillespie, and Esterly…

Rich-media representations of teaching using animated cartoons can be effective at stimulating teachers' discussion about practice and hence help them learn productively from one another about their profession. Our research aims to design web-based interactive rich-media virtual settings for teachers to learn to do the practice of teaching. For…
