Next Generation Science Standards (NGSS) were developed by 26 lead states with NSTA, AAAS, NRC, and Achieve in 2013 to provide a new vision for the teaching of science in U.S. schools. Teachers' applications have been mainly concentrated on efforts to align the current practices with the standards. Elementary science teachers need to use…

Policy documents in many nations, as well as international policies indicate that the goal of improved student science learning requires teachers to learn to use knowledge generation environments for teaching science. This is a particular challenge for early childhood teachers (kindergarten through grade two), who have historically valued…

National science proficiency scores in America have failed to show significant improvement for years (www.nationsreportcard.gov, 2019). Although policy reforms have come and gone in attempt to influence these trends, Disciplinary Literacy (DL) theory currently stands center-stage as one of the most recently espoused approaches to improving…

There is a call in science education for students to be in the business of "doing science," rather than "doing the lesson" (Jimenez-Aleixandre et al., 2000). Developing explanatory models is one important strategy for sensemaking in science. Teachers' knowledge plays a critical role in how classroom interactions are framed and…

This article presents the evaluation of a two-year action research project in biology and mathematics teaching involving a primary school and a university in Sweden. The aim of the study was to contribute knowledge about a school-university intersection as a professional learning arena. The teachers' conceptions about the project implementation,…

To organize for the improvement of science instruction teachers need opportunities to collaboratively learn from practice, in practice, and to engage in the revision of classroom tools. In this paper, we examine how a professional learning community (PLC), comprised of middle school teachers and researchers, worked on the improvement of Ambitious…

In this study, we examined how teachers involved in a yearlong technology integration initiative planned to enact technological, pedagogical, and content practices in science lessons. These science teachers, engaged in an initiative to integrate educational technology in inquiry-based science lessons, provided a total of 525 lesson plans for this…

The aim of this study is to examine the impact of the Technological Pedagogical Content Knowledge (TPCK) based educational practices in astronomy lectures on prospective science teachers' success levels. The study was conducted on 4th-grade prospective science teachers of a public university and lasted for 14 weeks. In the study,…

This paper is concerned with the conceptualization of pedagogical content knowledge (PCK) for teaching about the nature of science. In contrast to the view that science teachers need to develop a specific "PCK for nature of science," an alternative, more comprehensive notion of PCK for science teaching is suggested. The point of…

The ubiquitous goals of helping precollege students develop informed conceptions of nature of science (NOS) and experience inquiry learning environments that progressively approximate authentic scientific practice have been long-standing and central aims of science education reforms around the globe. However, the realization of these goals…

In a mixed-methods study, the authors investigate teacher typologies of elementary teachers (N = 132) in the United States based on their reformed science teaching beliefs. Additionally, the identified teacher typologies were compared with respect to their science content knowledge, self-efficacy and epistemic beliefs. Results revealed three…

Although the currently employed STEM (science, technology, engineering, and mathematics) acronym is of recent origin, dating to the early 2000s (Chute, 2009), the United States has long emphasized the importance of teaching STEM in its public schools. Early efforts, such as "Science, the Endless Frontier" (Bush, 1945) and the…

Across the globe, governments, industry and educationalists are in agreement that more needs to be done to increase and broaden participation in post-16 science. Schools, as well as teachers, are seen as key in this effort. Previous research has found that engagement with science, inclination to study science and understanding of the value of…

The classroom practices of science teachers are indicative of their beliefs and pedagogical content knowledge (PCK). PCK is an amalgam of knowledge about subject matter, pedagogy, and contextual issues. This article identifies areas where physics teachers in Lesotho may need professional development support by addressing the research question: How…

Designing professional development that effectively supports teachers in learning new and often challenging practices remains a dilemma for teacher educators. Within the context of current reform efforts in science education, such as the "Next Generation Science Standards," teacher educators are faced with managing the dilemma of how to…
