Evaluation of plausible alternative explanations of scientific phenomena is an authentic scientific activity. Instructional scaffolding can facilitate students’ engagement in such evaluations by facilitating their reflections on how well various lines of scientific evidence support alternative explanations. In the present study, we examined two forms of such scaffolding, with one form providing more autonomy support than the other, to determine whether any differential effects existed between the two.

Children who live in under-resourced communities and attend under-resourced schools deserve access to high-quality teachers and educational opportunities to support their success and well-being. This study emerged from a professional development (PD) for urban teachers working in such schools, to expand educational opportunities for elementary students through outdoor science teaching.

From the experiential learning perspective, this study investigates middle and high school students (n = 1009) who used an online module to learn about wildfire hazards, risks, and impacts through computational simulations of wildfire phenomena. These students were taught by 18 teachers in urban, rural, and suburban schools across the United States. We analyzed students’ simulation behaviors captured in log files, responses to an assessment administered before and after the module, and demographic surveys, as well as teachers’ responses to a post-module implementation survey.

Young children are naturally interested in light and shadows, thus providing a meaningful context to introduce preschool science investigations. As children explore how shadows are made and change, they also have opportunities to develop math skills, specifically visual spatial awareness. In this article, we describe a set of light and shadows activities. Through these playful hands-on and digital app investigations, children explore how shadows are made and change.

With a decade passing since the release of the Next Generation Science Standards (NGSS), it is timely to reflect and consider the extent to which the promise of science teaching and learning that values and centers learners’ varied epistemologies for scientific sensemaking has been realized. We argue that this potential, in part, lies in the hands of our science education research community becoming aware and intentional with how we situate learners’ language-related resources and practices in our work.

In this paper, we introduce an epistemic scaffolding framework for understanding the nature of support for epistemic growth in science. Our framework distinguishes between two patterns of epistemic scaffolding: implicit and explicit. Implicit epistemic scaffolding encompasses support integrated into contexts, activities, discourse, or tools, exerting an unconscious influence on learners’ epistemic thinking and practices. On the other hand, explicit epistemic scaffolding involves intentionally explicating the underlying epistemology of learners’ knowledge work.
