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…

This study examines an urban middle school teacher design team's capacity for creating integrated science, technology, engineering, and mathematics curricula. Using Brown's pedagogical design capacity (PDC) theory, which highlights interactions between personal and curricular resources, this paper introduces an extended framework that includes…

This paper is part of the special issue on Teacher Learning and Practice within Organizational Contexts. Shifting instructional practices in elementary schools to include more equitable, reform-based pedagogies is imperative for supporting students' development as science learners. Teachers need high quality professional development (PD) to learn…

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…

To gain a holistic understanding of how science teachers dealt with STEM education, this study explored two science teachers' perceptions and practices at primary schools via the lens of curriculum ideology. By examining their perceptions and practices from six essential aspects (i.e., aim, content, student, teaching, learning, and assessment), we…

Given the potential impact of introductory science laboratories on postsecondary students' science learning, careful thinking is needed about how to support teaching assistants (TAs) to create opportunities for their students to reason about science. Research suggests that teachers are best positioned to improve their teaching practices when they…

Science teachers struggle to implement and sustain new curricular ideas from professional development (PD) experiences. These PD opportunities are crucial for enacting real-world changes to teaching practice and address pressing global challenges, such as the teaching and learning of socioscientific topics nested in school communities.…

Although 20 states have adopted Next Generation Science Standards (NGSS), 24 other states have developed their own K-12 science standards based on the same National Research Council (NRC) Framework. Understanding what influences content standards developers, realizing the supports and impediments to implementation they foresee, and knowing their…

Through analysis of a classroom lesson led by a decorated teacher, we illustrate how instructional practices favor students seeking empirical patterns at the expense of using mechanistic reasoning. In the lesson, when students spontaneously come up with hypothetical mechanisms to explain why a light bulb in an electric circuit does or does not…

As the vision in "A Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS) takes hold in schools and classrooms, there is an urgent need for teacher professional development (PD) programs that align with NGSS-designed curriculum materials and address the unique strengths and needs of diverse student…

This article examines the tensions that arose as teachers, scientists, youth, and community organizers worked to develop a curriculum that was responsive to community concerns and the Next Generation Science Standards (NGSS). Within the context of urban heavy metal contamination and building on previous critiques of the standards, we identified…

The vision for science proficiency presented in "A Framework for K-12 Science Education" calls for significant shifts in both teaching and assessment. In this paper, we describe an effort to develop and validate a set of "proximal transfer tasks" for high school biology classrooms where teachers were implementing a…

Curriculum materials are important resources with which teachers make pedagogical decisions about the design of science learning environments. To become well-started beginning elementary teachers capable of engaging their students in inquiry-based science, preservice elementary teachers need to learn to use science curriculum materials…

We explored whether existing curricula can be adapted to increase students' skills at comprehending and learning from diagrams using an intervention delivered by regular middle-school teachers in intact classrooms. Ninety-two teachers in three states implemented our modified materials over six curricular units from two publishers: "Holt"…

Teachers often engage in curricular planning by critiquing and adapting existing curriculum materials to contextualize lessons and compensate for their deficiencies. Designing instruction for students is shaped by teachers' ability to apply a variety of personal resources, including their pedagogical content knowledge (PCK). This study…
