Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

Explicitly attending to justice in science teaching and learning is long overdue. Here, we examined the professional teacher identity development of 13 science teachers as they collaborated in networked professional learning communities (PLCs) to implement and revise a culture-setting unit focused on the science of COVID and engaging in…

This is a study intended to address white supremacy in science education. To accomplish this, we describe how one White intern, Boaz, learned to teach science in anti-racist ways. By detailing how whiteness mattered in his learning to teach, we demonstrate that whiteness is potentially constant in White peoples' learning to teach science in…

Although previous research provides insights into how gestures function as a pedagogical tool, relatively little is known about how gesture is related to language, together creating a key meaning-making teaching resource. Drawing on the system of logico-semantic relations in Systemic Functional Linguistic theory and McNeill's description of…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Increasing access to computational ideas and practices is one important reason to integrate computational thinking (CT) in science classrooms. While integrating CT into science classrooms broadens exposure to computing, it may not be enough to ensure equitable participation in the science classroom. Equitable participation is crucial because…

Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

The purpose of this article is to introduce a methodology for analyzing the complex configurations emerging in students' speech and drawing activities, having consequences for how and what students learn and make meaning of in science. Accordingly, we launch a methodology to unfold the multidimensional communication as to deepen the analysis of…

National governments are concerned about the disconnection of young people from science, which hampers the development of a scientifically literate society promoting sustainable development, wellbeing, equity, and a green economy. Introduced in 2015 alongside Agenda 2030, the "open schooling" approach aims at enhancing students' science…

Multiple external representations (MERs) are useful for teaching complex content in science education. An open question is whether there is an especially effective way to sequence MERs. On the one hand, the so-called concreteness fading approach suggests starting instruction with more concrete representations and proceeding stepwise to more…

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful--respected by students,…

As professional science becomes increasingly computational, researchers and educators are advocating for the integration of computational thinking (CT) into science education. Researchers and policymakers have argued that CT learning opportunities should begin in elementary school and span across the K-12 grades. While researchers and policymakers…

Narrative texts have been advocated as tools to tackle science learning challenges, and there is even the proposal of a "narrative effect" on learning. We believe it is necessary to examine previous evidence on this effect, as well as to characterize the process of learning through science narrative texts more broadly. In this article,…

Student participation in the science practices is more than following directions to conduct pre-determined experiments and analyze data with expected solutions. This requires classroom shifts that increase the epistemic agency of students: increase student involvement and authority in developing science knowledge and practices, rather than the…

There is a considerable amount of research on the nature and effectiveness of modeling as applied to student learning in science. However, few studies have examined the role of students' epistemic uncertainty in modeling and how teachers collaborate with students to recognize and utilize it as a pedagogical resource to support productive struggle…
