This essay opens with a question about what science teaching would look like in a world where categorical seams of human diversity were not probabilistic determinants of science learning. After revisiting Hewson and Hewson's description of an "appropriate conception of science teaching," I detail the ways in which the field of science…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…

This paper's focus is on the "middle" of partnerships for equity in science education. Middle is used in a temporal sense, meaning the time after the general purposes and terms of working together have been set and before outcomes have been achieved. The middle of the partnership also represents people interacting, bounded around the…

Instructional explanations are sometimes viewed as part of a nonconstructivist, solely teacher-centered learning environment, leading to the perception that they are ineffective or inappropriate for teaching science. Consequently, teacher education programmes seldom focus on preparing teachers to explain scientific concepts effectively.…

Current science instruction does not educate K-12 students equitably and creates short- and long-term impacts on individual students and society. While students may be present in class, they may not have access to quality science learning experiences. The goals of this paper are to show how science instruction may not be reaching its aim of…

Research has recommended centering health disparities to make science instruction relevant to students from minoritized racial and ethnic groups. While promoted as a recent innovation, the repurposing of science instruction to improve the health of demographic groups has a longer history traceable to segregated and colonial schooling. Using a…

Drawing upon interviews with key actors involved in the development of and support for the Next Generation Science Standards (NGSS) in the United States, this article shows how a potentially controversial reform came to be actively supported by senior educators. We utilize Kingdon's (2003, "Agendas, alternatives, and public policies,"…

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…

The program team operating an NSF Noyce Master Teacher program has been building a conceptual framework for developing teacher leaders. The program has focused its efforts on a group of 16 chemistry and physics teachers in Southeast high-needs schools. The conceptual framework is based on the view that teacher leaders are those individuals who…

In this paper, we contend that what to teach about scientific reasoning has been bedeviled by a lack of clarity about the construct. Drawing on the insights emerging from a cognitive history of science, we argue for a conception of scientific reasoning based on six "styles of scientific reasoning." Each "style" requires its own…

While current science teacher education frameworks designed to support high-quality teaching have the potential to promote equitable science learning, they do not substantively engage with how racism organizes science teaching and learning. In this critical qualitative inquiry grounded in critical race theory and sociopolitical perspectives on…

When collecting data, science education researchers frequently have multiple respondents evaluate multiple artifacts using multiple criteria. Herein, the authors introduce Multifaceted Rasch Measurement (MFRM) analysis and explain why MFRM must be used when "judges'" data are collected. The authors use data from elementary science…

This paper explores the relationship between epistemology, sociology, and learning and teaching in physics based on an examination of literature from research in science studies, history and philosophy of science, and physics pedagogic research. It reveals a mismatch between the positivist epistemological foundation which seems to underpin the…

Failure to improve achievement in K-12 science for racially minoritized students and students living in poverty continues to challenge the inclusionary rhetoric of "science for all." Science education researchers, teacher educators, and educators must consider the racialized and classed inequalities that continue to limit students'…

Even though human racial difference has been a longstanding topic of the school biology curriculum, there is little evidence that contemporary biology textbooks challenge stereotypical racial beliefs that are based in biological thinking. Rather, the modern biology curriculum may be a place where such beliefs about race are perpetuated…
