This longitudinal study examines the relationship between students' knowledge-in-use performance and their performance on third-party designed summative tests within a coherent and equitable learning environment. Focusing on third-grade students across three consecutive project-based learning (PBL) units aligned with the Next Generation Science…

This research explored kindergarten students' learning of simple particle models to explain the properties and behavior of matter in the solid, liquid, and gas states and during phase transitions (evaporation, melting, freezing, and condensation). Science instruction for young learners tends to focus on the concrete and directly observable. This…

Recently, there has been a surge of literature on the implementation of translanguaging pedagogy and practices in science education settings. By activating and validating learners' full communicative repertoire, translanguaging holds promise to build an inclusive science learning community where multilingual learners' ways of knowing are not only…

Research on translanguaging in science and engineering education has grown rapidly. Studies carried out across diverse contexts converge in their commitment to fostering equity in science and engineering learning for linguistically marginalized learners. However, the rapid growth of this research area has exposed different approaches to…

Design-based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta-analysis that would give a comprehensive picture of how DBL is connected to student achievement in different…

The pandemic outbreak of COVID-19 has highlighted an urgent need for infectious disease education for K-12 students. To gather a better understanding of what educational interventions have been conducted and to what effect, we performed a scoping review. We identified and examined 23 empirical researcher- and teacher-designed studies conducted in…

Recent consensus documents in science education (e.g., the Next Generation Science Standards) emphasize helping students develop facility with constructing and critiquing both claims and the evidence that supports them. While students typically view evidence as necessary for supporting scientific claims, they tend to "objectify"…

This article examines kindergarten children's (5-6 years old) engagement in scientific practices, with a focus on generating and using evidence to support claims, during a 5-month project about snails. The research questions are as follows: (1) what meanings do kindergarteners construct for what constitutes evidence? How are those meanings…

Engaging in systemic reasoning about ecological issues is critical for early elementary students to develop future understanding of critical environmental issues such as global warming and loss of biodiversity. However, ecological issues are rarely taught in ways to highlight systemic reasoning in elementary schools. In this study, we conducted…

Spatial discontinuity between causes and effects is a feature of many scientific concepts, particularly those in the environmental and ecological sciences. Causes can be spatially separated from their effects by great distances. Action at a distance, the idea that causes and effects can be separated in physical space, is a well-studied concept in…

This study draws on data from a 10-month critical narrative inquiry of science teaching and learning in a third grade, dual language, integrated co-teaching classroom. The teachers were participants in a 14-week science professional development seminar that enrolled inservice and preservice teachers and focused on enhancing science teaching and…

In this study we explored how dramatic enactments of scientific phenomena and concepts mediate children's learning of scientific meanings along material, social, and representational dimensions. These drama activities were part of two integrated science-literacy units, "Matter" and "Forest," which we developed and implemented…
