Wind musical instruments are affected in their intonation by temperature. We show how to account for these effects in a simple experiment, and provide results in languages accessible to both physics and music professionals.

A.V. Usova (1921-2014) has always been one of the leading figures in Russian physics education. Her theory of physics concept formation was formulated during the 1970s and the 1980s and directly influenced the process of physics education in the 20th and the 21st century. Over the years there have been a lot of theories of concept formation. Her…

An integrative introduction to the sciences and an introduction to scientific writing can provide a strong foundation for broadly trained STEM majors to explore the interconnectedness of STEM disciplines and prepare them for scientific research. These goals have been accomplished through a sequence of two first-year courses, STEM 101: Integrative…

Traditional school science has been described as focused on indisputable facts where scientific processes and factors affecting these processes become obscured or left undiscussed. In this article, we report on teachers' perspectives on the teaching of sociocultural and subjective aspects of the nature of science (NOS) as a way to accomplish a…

Doing science involves the development and evaluation of models. These models are not objective truths but can be understood as explanations, which scientists use to explore and reason about an aspect of the world. Learning science involves students expressing and engaging with models in the classroom. However, this learning should not be seen as…

The aim of the present study was to investigate the influence of the explicit nature of science instruction embedded in the Argument-Driven Inquiry method compared with an implicit inquiry method on eleventh grade students' conceptions of NOS. The study used a pre-/post-test control group design to investigate the influence of the explicit nature…

Imines are important in biological chemistry and as intermediates in organic synthesis. An experiment for introductory undergraduate organic chemistry is presented in which benzaldehyde was condensed with "p"-methoxyaniline in toluene to give 4-methoxy-"N"-(phenylmethylene)benzenamine. Water was removed by azeotropic…

Deans for Impact, a nonprofit organization composed of leaders of educator-preparation programs throughout the U.S., believes cognitive science is an important part of an evidence-based core of knowledge that preservice teachers should possess. Member deans believe that cognitive science holds promise for improving learning and promoting the…

We present an empirical investigation of a classroom training fostering vocational students' consideration of source information when deciding about science-based controversies. The training was specifically aimed at raising students' awareness of the division of cognitive labor and the resulting need to take a source's competence into account…

A Cartesian diver can be used to measure the surface tension of a liquid to a certain extent. The surface tension measurement is related to the two critical pressures at which the diver is about to sink and about to emerge. After sinking because of increasing pressure, the diver is repulsed to the centre of the vessel. After the pressure is…

Vortex cannons have been used by physics teachers for years, mostly to teach the continuity principle. In its simplest form, a vortex cannon is an empty coffee can with a hole cut in the bottom and the lid replaced. More elaborate models can be purchased through various scientific suppliers under names such as "Air Cannon" and…

Gas diffusion, as a basis for complex biological processes such as respiration, is a core principle for understanding fundamental physiology. Students, however, often find these concepts challenging, in particular when expressed formally as in Fick's law of gas diffusion. This introduction to Fick's law uses the representations of…

In the present paper we suggest an original physical explanatory model that explains the mechanism of the sound amplification process in a stethoscope. We discuss the amplification of a single pulse, a continuous wave of certain frequency, and finally we address the resonant frequencies. It is our belief that this model may provide students with…

Thin film interference manifests itself in a wide range of visually pleasing situations in everyday life (in the colored effects caused by a drop of oil on water, in soap bubbles, etc.) and is also involved in important technical applications (semi-reflecting mirrors, anti-reflection lenses, etc.). Yet, despite its familiarity, high school…

This article addresses the role of imagination in social work education, practice, and research. Following a brief discussion of terms, the author attempts to identify the various contributions of human imagination to social change processes. The second part presents the argument that the cultural structure known as Social Darwinism significantly…
