Next Generation Science Standards (NGSS) call for integrating knowledge and practice in learning experiences in K-12 science education. "PlantingScience" (PS), an ideal curriculum for use as an NGSS model, is a computer-mediated collaborative learning environment intertwining scientific inquiry, classroom instruction, and online…

With the demand for quality quantitative instruments in the field of science education rising, additional measures of currently unassessed affective variables need to be constructed. In this study, we discuss the survey creation and evaluation process of the STEM Awareness Community Survey (SACS) through an application of Liu's (Liu, X.,…

Although the core work of science is oriented toward constructing, revising, applying, and defending models of the natural world, models appear only rarely in school science, and usually only as illustrations, rather than theory building tools. We describe the rationale and structure for a learning progression to understand the development of…

Assuming that quality science education plays a role in economic growth within a country, it becomes important to understand how education policy might influence science education teaching and learning. This integrative research review draws on Cooper's methodology (Cooper, 1982; Cooper & Hedges, 2009) to synthesize empirical findings on the…

Scientific argumentation and explanation are essential practices of science that have been highlighted as equally important for K-12 science education. However, as Osborne and Patterson (2011) have recently argued, both the term "argument" and "explanation" have multiple, overlapping, meanings, and uses in science education. In this article, the…

In this position paper, we examine the science teaching orientation component of the S. Magnusson, J. Krajcik, and H. Borko (1999) pedagogical content knowledge (PCK) model for science teaching. We trace the origin of the construct in the literature, identifying multiple definitions that have lead to ambiguity. After examining published studies…

Argumentation is a central goal of science education because it engages students in a complex scientific practice in which they construct and justify knowledge claims. Although there is a growing body of research around argumentation, there has been little focus on developing a learning progression for this practice. We describe a learning…

During the past decade science educators have taken steps to identify seminal structures and approaches of science teacher professional development. This literature, which is increasingly informing how and in which contexts professional developers design and implement programs, states that scientists' divergent research interests and knowledge…

Science education reform has long focused on assessing student inquiry, and there has been progress in developing tools specifically with respect to experimentation and argumentation. We suggest the need for attention to another aspect of inquiry, namely "mechanistic reasoning." Scientific inquiry focuses largely on understanding causal…

Identity formation is a critical dimension of how and why students engage in science to varying degrees. In this paper, we use the lens of identity formation, and in particular identities in practice, to make sense of how and why Melanie, over the course of sixth grade, transformed from a marginalized member of the science class with a failing…

Using the US national sample from the Third International Mathematics and Science Study (TIMSS) and the Rasch modeling method, this study identified the conceptual progression sequence of various matter concept aspects, and compared students' latent abilities against the sequence. We found that the four matter aspects, i.e. conservation, physical…

Responding to the increasing math and science teacher shortage in the United States, this study intended to determine which science, engineering, and math (SEM) majors during which years in their undergraduate education and from which academic performance levels are most interested in K-12 teaching. Results may aid policymakers and practitioners…

In this paper, we report work undertaken with a group of 11 UK teachers over a period of a year to teach aspects of the nature of science, its process, and its practices. The teachers, who taught science in a mix of elementary, junior high, and high schools, were asked to teach a set of "ideas-about-science" for which consensual support had been…

Analyzes how educators currently frame historical stories to portray the process of science. Discusses the importance of narratives of error and recovery from error in illustrating the nature of science and its limits. Emphasizes history that conveys the nature of science effectively. (Author/KHR)

Debates the strengths and limitations of standards-based science education reform in the United States. Examines California science content standards and critiques it and the ways that such standards narrowly frame science education for the state's teachers and students. Suggests awareness of the challenges in using standards to achieve education…
