This article reports on a design-based implementation research (DBIR) project that addresses the question: "How can classrooms be supported at scale to achieve the three-dimensional learning goals of the Next Generation Science Standards?" Inherent in this question are three key design challenges: (i) "three-dimensional…

This study was conducted in a large-scale environmental literacy project. In the project, we developed a Learning Progression Framework (LPF) for matter and energy in social-ecological systems; the LPF contains four achievement levels. Based on the LPF, we designed a Plant Unit to help Levels 2 and 3 students advance to Level 4 of the LPF. In the…

This study developed learning progression-based measures of science teachers' content knowledge (CK) and pedagogical content knowledge (PCK). The measures focus on an important topic in secondary science curriculum using scientific reasoning (i.e., tracing matter, tracing energy, and connecting scales) to explain plants gaining weight and…

Our society is currently having serious debates about sources of energy and global climate change. But do students (and the public) have the requisite knowledge to engage these issues as informed citizenry? The learning-progression research summarized here indicates that only 10% of high school students typically have a level of understanding…

This study investigates the fate of claims made by middle school science students working in collaborative groups in a multicultural urban classroom and the concomitant effects on engagement and understanding. Given problems of a complex and open-ended nature in a learning community setting, students were challenged to establish group positions…

Compares approaches to defining functional scientific literacy and helping students achieve it--the canonical approach focuses on literate individuals' knowledge, skills, and habits of mind; the sociocultural approach focuses on factors such as values, which affect participation in the community's activities. Offers a case study to show how these…

Describes a physics course designed to engage preservice elementary teachers in the practices and discourses of science through activities that would later be used with children. Presents an account of preservice teachers' progress in inventing and testing models, working with empirical data, critically evaluating and using authoritative sources,…

This paper describes a sequence of lessons based on a modified version of the ESS Colored Solutions problem posed in an urban multicultural middle school setting in which students often worked in collaborative groups. As students encountered observable phenomena, they were encouraged to record techniques and observations, search for patterns in…
