Practices of generating, analyzing, and using evidence play a central role in the Framework for K-12 Science Education and the NGSS. However, the construct of evidence remains largely underspecified in these documents, providing insufficient guidance on how to engage students with the broad and complex nature of evidentiary reasoning. This creates…

Teaching about nature of science (NOS) is considered as an important goal of science education in various countries. Extensive empirical research about how some aspects of NOS can be effectively taught is also available. The most widely adopted conceptualization of NOS is based on a small number of general aspects of NOS, which fall into two…

The push for STEM has raised the visibility of engineering as a discipline that all students should learn. With the release of the "Framework for K-12 Science Education" and the Next Generation Science Standards (NGSS), engineering now has an official place in the science curriculum. In both the "Framework" and the NGSS,…

Biology instructors from middle school to university level recognize that natural selection is an essential topic in the curriculum. Numerous studies have shown the prevalence of many alternative conceptions about evolution that persist despite instruction in student populations all over the world. Having valid, reliable and easily used…

This comment was written in the spirit of restoring the productivity and visibility of science education research and to frame a more provocative and formative role in directing efforts to modernize teaching. (PR)

A model of the character and mechanism for knowledge restructuring is presented and a model of educational practice designed to facilitate this form of restructuring is described. A broadened and integrated view of assessment and instruction called a portfolio culture, central to the educational model, is discussed. (KR)

After proposing and defining the superordinate concept of "historicality," fundamental interrelationships between time, events, memory, meaning, personal knowledge, public knowledge, and the histories of science are explored. Relevant research findings that demonstrate the confluence of scholarly thought concerning historicality across…

There is a need for research that depicts better-differentiated social contexts for science education in their full complexity. Social scientists have developed a promising model for research in context. Three critical conceptual and methodological strands of the model are discussed, along with their implications for science education research.…

Presents the focus of this theme issue that is devoted to examining critical, feminist, and poststructural theories and the implications these theories have for considering the ideal, a science education for all children. (PVD)

The WISE Group is a group of women who have been exploring feminism and relationships among teaching, research, and activist goals. The Call to Action illustrates the different arguments about science teaching and learning, one from a more traditional perspective and another from a feminist perspective. The primary goal of activism is to challenge…

The article to which this essay responds advises risky practices that trouble traditional distinctions between science and not-science (things not scientific in nature), particularly its argument to politicize science as a way to organize teaching. Raises questions about science as a regime of truth in a place where such questions carry much…

Selective illustrative examples of students' learning difficulties and misconceptions in first-year general and organic chemistry are presented in the students' terms, followed by strategies the author uses to overcome the difficulties. Suggests that student misconceptions in first-year chemistry are not interrelated logically and are not prone to…

Provides examples of how concept mapping can be used to help overcome misconceptions in college chemistry. (PR)
