Cultivating students' scientific knowledge and developing their capability in scientific inquiry depends on a teacher's ability to use existing resources to design rich learning opportunities. Designing such experiences is not easy, and is particularly challenging for new teachers who have little experience making decisions about the best way to…

Science students should use mathematical and computational thinking to explain phenomena, but few examples of teachers engaging students in this important scientific practice have been found. This article describes a strategy for enhancing a lesson in which students use a mechanistic model to explain friction by adding mathematical and…

The vision of Next Generation Science Standards (NGSS) "requires a dramatic departure from approaches to teaching and learning science occurring today in most science classrooms K-12" (Reiser 2013, p. 2). In this article the authors emphasize the importance of examining student misconceptions and correcting them with sense-making…

In this article Campbell and Neilson discuss several design strategies developed or adopted that were found particularly helpful when sequencing a unit that focused on learning about motion and acceleration. Students were expected to predict, observe, and explain why a ball traveled down one ramp faster than the other. Before engaging students,…

Sense-making has been described as working on and with ideas--both students' ideas and authoritative ideas in texts--to build coherent storylines, models, and/or explanations. This article describes the process for developing storyline units to support students' making sense of and explaining a rocket launch. The storyline approach, which aligns…

As the ethnic and racial diversity in U.S. classrooms continues to grow, myths about the education of English Language Learners (ELLs) persist, while many teachers feel ill-prepared to meet these students' academic needs. This article focuses on myths shared by in-service science teachers enrolled in a master's program at the University of Texas…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

Teachers do not work in a vacuum. They are, in most cases, part of a science department in which teachers and the chairperson have important roles in science education reform. Current reform is shaped by national standards documents that emphasize the pedagogical and conceptual importance of best practices framed by constructivism and focused on…

Model-Based Inquiry (MBI) is an emergent instructional strategy that is gaining acceptance among science educators. This approach to learning realistically mirrors the work of scientists, who develop and test hypotheses to construct more sophisticated understandings of the natural world. This article details how the authors collaboratively taught…
