Science education policies and standards have called for educators to teach students about the Nature of Science (NOS) and engage them in Culturally Relevant Science Teaching (CRST), which requires critical shifts away from traditional science teaching. As such, teachers are being asked to possess or take up conceptions of science that challenge…

This study explored a middle school science teacher's curricular sensemaking in interaction with their use of an educative storyline curriculum, aligned to the Next Generation Science Standards, that was intentionally designed for more opportunities for students' scientific sensemaking. Using a phenomenological case study methodology, we examined…

Science teachers and educators seek to promote equity and inclusion within their classrooms. Yet, many do not examine how their roles could reproduce oppression that continues to exclude certain groups of students. Centering on how oppression interacts with science teaching and learning, this naturalistic study observed Ms. William and her…

The teaching of science in K-12 schools has long been criticized as a process that propagates oppression for students who do not conform to entrenched norms of gender, sex, and sexuality. Academic standards, curriculum, and textbooks are rife with rhetoric that reinforces any deviation from cisheterosexuality as aberrant, unusual, or abnormal.…

In this study, we investigated how students organized their knowledge about organic chemistry reactions in a transformed curriculum, including their choices, abilities, and changes over time. This transformed curriculum focuses on interpreting the underlying mechanistic patterns of chemical reactions and emphasizes the principles of reactivity in…

Nearly a decade ago, the "Framework for K-12 Science Education" argued for the need to intertwine science and engineering practices, disciplinary core ideas, and crosscutting concepts in performance expectations. However, there are few empirical examples for how intertwining three dimensions facilitates learning. In this study, we used a…

In recent years, there has been a strong push to transform STEM education at K-12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge…

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in…

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…

Efforts to reform undergraduate chemistry laboratory coursework typically focus on the curricula of introductory-level courses, while upper-level courses are bypassed. This study used video-stimulated recall to interview 17 junior- and senior- level chemistry majors after they carried out an experiment as part of a laboratory course. It is assumed…

Educative curriculum materials provide teachers with authentic opportunities to learn new skills and practices. Yet, research shows teachers use curriculum in different ways for different reasons, and these modifications could undermine the learning goals of the curriculum. Little research, however, has examined the variation in teacher use of…

This study reports on an innovative version of adaptive primary literature (APL) that we call Science Behind the Scenes used during a summer professional development (PD) program. Classroom teachers read and discussed papers from the primary literature, and created translations of these papers relevant to their own classroom needs. We randomly…

Scotland is one of several countries to have recently implemented a new national curriculum to highlight 21st century educational priorities. Teachers have been mandated to follow the new curriculum guidelines, known as Curriculum for Excellence (CfE), since the fall of 2010. The purpose of this study was to use a phenomenological lens to…

Many students feel the curriculum is detached from their lives and interests. Indeed, about half the questions asked by high school biology students are not addressed by the curriculum. This study presents a strategy to incorporate students' curiosity questions into the curriculum as a way to reduce the disparity between students' interests and…

Teachers participating in curricular reforms, especially reforms based on constructivism, are expected to bring about change in their teaching approach. This is often a difficult, complex and intensive process, and demands a radical reculturing of the classroom. This is also the case for social constructivist reforms in chemistry education, which…
