Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in…

The vast and rapidly growing amount of science education research makes it challenging for researchers to navigate and synthesize developments across the field, particularly concerning broad concepts evolving along divergent paths. To address this issue, a novel review methodology employing bibliometrics and network analysis was tested to identify…

This study addresses the measurement of high school students' epistemic knowledge associated with scientific experimentation (EKSE) which concerns "how" scientific experimentation generates knowledge and "why" that knowledge is justified. Based on philosophical, educational standards, and literature analyses, an EKSE construct…

Adopting new instructional materials is an important way to support reform in science education, but implementation can be challenging and complex. Therefore, we conducted a contrasting case study of two middle schools implementing new curricular materials. We conducted semi-structured interviews with teachers and leaders and collected…

Although existing literature suggests that teachers perceive, mobilize, and leverage resources to support ambitious instruction, less is known about how teachers and students jointly take up resources for co-constructing scientific knowledge. This study examines how teachers and students utilize aspects of practice-oriented curriculum materials…

Science education that fosters scientific competency and engagement prepares students to become informed civic participants in modern society. Teaching strategies that encourage scientific engagement are especially important in rural settings, as these students are less likely to pursue scientific careers or use science in their everyday lives. To…

Mechanistic reasoning is a powerful form of reasoning central to scientific explanations. Despite mechanistic reasoning being an important dimension of scientific practice and a central dimension of science curricula, students face difficulties in developing such type of reasoning. Many authors have been proposing tools for supporting its…

The aim of this study is to develop more understanding about strategies to support teachers' professional development in curriculum innovations, in which pedagogy and content change simultaneously compared to the conventional curriculum. A pre-existing framework, including strategies for professional development, was adapted, implemented, and…

This study examines how researchers can better understand the instructional and practical realities of teachers through collective sensemaking. Traditional approaches to curriculum design engage learning models without accounting for the needed flexibility of teachers. This approach has resulted in tension and gatekeeping--inhibiting the…

Programs that bring teachers and scientists together have continued to achieve attention as important potential contributions to science education. Often, however, those programs place teachers in the position of learner or apprentice to the scientists. This study examines a teacher-scientist partnership program (two project sites, two teachers…

The growing popularity of mobile technologies in educational settings, from grade schools through college, has prompted science educators to prepare preservice teachers to successfully integrate technology into science teaching. This mixed-methods study explores the effectiveness of a mobile technology-based physics curriculum, Exploring Physics,…

Broad misconceptions about global climate change (GCC) could hinder efforts to address this large-scale problem, and curricular materials can play a substantial role in what students learn about GCC. This study examines how U.S. high school textbooks and supplemental curricular materials published between 2007 and 2012 portray the causes,…

This study examines and compares how developers designed two primary science curricula to support teacher adaptation and enable use of innovative materials at scale. The two cases--"Literacy Science" (a science and literacy curriculum for grades 2-5) and "Science as Inquiry" (a curriculum focused on matter for grades 3-5)--were…

Transformative experience refers to learning episodes in which students use ideas from the science classroom to see and experience the world differently in their everyday lives. The construct is defined by three characteristics: (1) motivated use (application of learning in "free-choice" contexts), (2) expansion of perception (seeing…

Large investments are made in curriculum materials with the goal of supporting science education reform. However, relatively little evidence is available about what features of curriculum materials really matter to impact student and teacher learning. To address this need, the current study examined curriculum features associated with student and…
