Practices of generating, analyzing, and using evidence play a central role in the Framework for K-12 Science Education and the NGSS. However, the construct of evidence remains largely underspecified in these documents, providing insufficient guidance on how to engage students with the broad and complex nature of evidentiary reasoning. This creates…

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…

While research on and development of evidence-based instructional practices (EBIPs) in STEM education has flourished, implementation of these practices classrooms has not been as prolific. Using the teacher-centered systemic reform model as a framework, we explore the connection between chemistry instructors' beliefs about teaching and learning…

One barrier to the adoption of evidenced-based teaching practices may be that faculty do not see teaching as an important part of their identities as professionals. Graduate school is a key time for professional identity development, and currently we know little about how doctoral students develop identities as college teachers. In this…

This article evaluates a validity argument for the degree to which assessment tasks are able to provide evidence about knowledge that fuses information from a progression of core disciplinary ideas in ecology and a progression for the scientific practice of developing evidence-based explanations. The article describes the interpretive framework…

This study documents how an urban high school science teacher engaged her English Language Learners (ELLs) in the discourse-intensive science and engineering practices of (1) arguing from evidence and (2) obtaining, evaluating, and communicating information. The teacher taught an introductory integrated science course to classes with a large…

Assessing the credibility of evidence in complex, socio-scientific problems is of paramount importance. However, there is little discussion in the science education literature on this topic and on how students can be supported in developing such skills. In this article, we describe an instructional design framework, which we call the Credibility…

In this study, we analyzed the quality of students' written scientific explanations found in notebooks and explored the link between the quality of the explanations and students' learning. We propose an approach to systematically analyzing and scoring the quality of students' explanations based on three components: claim, evidence to support it,…
