We present a comment on "Benefits of completing homework for students with different aptitudes in an introductory electricity and magnetism course", by F. J. Kontur, K. de La Harpe, and N. B. Terry PRST-PER 11, 010105 (2015). Our data show that the conclusions Kontur and coworkers draw from their data may not be generally applicable.

We reply to Rieger, Reinsberg, and Wieman's forgoing Comment [Phys. Rev. Phys. Educ. Res., Comment on "Benefits of completing homework for students with different aptitudes in an introductory electricity and magnetism course" 12, 028001 (2016)].

In this commentary, the author presents his thoughts on two papers appearing in this special issue. The first, "The Importance of Language in Students' Reasoning about Heat in Thermodynamic Processes," by David T. Brookes and Eugenia Etkina (See: EJ1060728), and the second, "Varying Use of Conceptual Metaphors Across Levels of…

It is argued that the correct answer to the three questions in the title is "no": that the theses being denied derive from traditional philosophy, not from the way the quantum theories are used. For example, the calculation of the energy spectrum of an atom assumes the autonomous existence of the atom, rather than its dependence upon the observer.…

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,…

The last couple of decades have seen an enormous development in the study of embodied cognition through the investigation of conceptual mappings, such as conceptual metaphor and conceptual blending. Initially, this progress was achieved at a theoretical level, and more recently through empirical research in basic science--from psycholinguistics,…

This paper argues that the metaphorical representation of concepts and the appropriation of language-based construals can be hypothesized as additional sources of conceptual change alongside those previously proposed. Analyses of construals implicit in the lay and scientific use of the noun "energy" from the perspective of the theory of conceptual…

Every year, Americans spend billions of dollars on bottled water. They purchase a bottle from the vending machine or buy a case at the grocery, no longer considering the water that's freely available from their taps. As consumers and as citizens, however, Americans should pause to study the personal and public consequences of this choice. In this…

Eight examples of innovative and outstanding earth science programs are described. These programs were selected using state criteria and at least four independent reviewers. While Project Synthesis offered a desired state, these examples of excellence provided views of what is already a reality. The goals of an exemplary science program are…

Draws a distinction between the terms "heat and work" and "energy" in terms of the teaching of thermodynamics. Gives examples using enthalpy and constant pressure processes, free energy and spontaneity, and free energy and available mechanical energy. Concludes that there is no thermodynamic role for the terms "heat"…

Energy as an abstract concept is discussed, and the effect of using inappropriate language in the teaching of energy is considered. The storage of energy is illustrated using gravitation and the combustion of coal as examples. (CW)

This document describes 10 examples of innovative and outstanding science/technology/society (STS) programs. These programs were selected using state criteria and at least four independent reviewers. While Project Synthesis offered a desired state, these examples of excellence provided views of what is already a reality. The goals of an exemplary…

Ten examples of innovative and outstanding middle school/junior high science programs are described. These programs were selected using state criteria and at least four independent reviewers. While Project Synthesis offered a desired state, these examples of excellence provided views of what is already a reality. The goals of an exemplary science…

Reports on the recommendations made by House Representative Don Fuqua (Florida), outgoing chairman of the Science and Technology Committee, regarding science policy in the United States. Includes issues such as research funding, the role of the universities, and the need to develop diverse energy sources. (TW)

This 12-chapter book examines different phenomena as viewed by those trained in physics. These views (or vistas) are promulgated to demonstrate that the infinite variety of things seen in the material world can be reduced to a handful of general laws and to share with the public the richness of the scientist's world view. The phenomena examined…
