In this mixed-methods study, we introduce an activity-based perspective on mathematical authority that considers who leads mathematical activities in a classroom. Our framework for mathematical authority extends existing research that focuses primarily on Authoring mathematical ideas to include the activities of Visualizing and Speaking. Using…

Access to drinking water is becoming more limited as drought persists across continents. This article highlights a particularly impacted group of students due to increasing drought conditions and upstream river pollution near their reservation. While there are related water and modeling standards across the K-12 Next Generation Science Standards…

In this article, the authors unveil the Trade Book Inquiry Design Model (IDM) blueprint. Anchored in a compelling question inspired by a trade book, the new blueprint is broken into two instructional blocks: "Reading and Comprehension" and "Living Social Studies." The inquiry template is designed to be instructionally efficient…

This article is a presentation of a three-day sequence of lessons that engaged fifth-grade students in an exploration following the activities of scientists. From asking questions and analyzing data, to engaging in scientific modeling, to defending their theories to the scientific (classroom) community, these fifth graders were mirroring how…

The Next Generation Science Standards call for changes in not only what is taught in elementary science but also how students engage in the learning experience to develop understanding of core disciplinary ideas. In this study we examined 5th-grade teachers' pedagogical content knowledge (PCK) for 1 particular core idea: the small particle model…

This study evaluated the Science and Literacy Instructional Model aimed at helping primarily Hispanic bilingual/English Learners (ELs) and economically disadvantaged fifth grade students with science achievement as measured by high-stakes standardized science achievement scores. The model combined purposeful planning, innovative academic…

The American legislation of No Child Left Behind resulted in a boom in scripted, prepackaged curricula for improving student outcomes. At the same time, greater attention to the needs of diverse populations also took prominence, resulting in a new area of study, culturally relevant/responsive pedagogy. The current view is that scripted curriculum…

This paper focuses on one Grade 5 class (9 females; 9 males) who worked in student-pairs to view five digital learning object (DLO) lessons created by the authors and meant to introduce students to the nature of models, the particle nature of matter, and physical change. Specifically, the paper focuses on whether DLO design elements could assist…
