Physics students often have problems understanding waves. Over the years numerous mechanical devices have been devised to show the propagation of both transverse and longitudinal waves (Ref. 1). In this article an updated version of an early-20th-century transverse wave machine is discussed. The original, Fig. 1, is at Creighton University in…

The French utopian socialist Charles Fourier is a key figure in Walter Benjamin's "Arcades Project". For Benjamin, one of the most significant aspects of Fourier's utopian vision was its conceptualisation of work as a form of play. According to Fourier it would be possible to build a world around people's inherent desires. In such a…

In this article we reviewed the main concepts of detonative combustion. Concepts of slow and fast combustion, of detonation adiabat are introduced. Landmark works on experimental and semi-empirical detonation study are presented. We reviewed Chapman-Jouguet stationary detonation and spin detonation. Various mathematical model of detonation wave…

The word "wave" is part of the daily language of every student. However, the physical understanding of the concept demands a high level of abstract thought. In physics, waves are oscillating variations of a physical quantity that involve the transfer of energy from one point to another, without displacement of matter. A wave can be…

On the first day of class I ask my students, "What makes a true statement true?" Then I tell them that they might be surprised to learn that there are only two types of true statements in physics, and I encourage them to try to discover the two categories.

Due to the lack of success of German students in recent program for international student assessment (PISA) studies since 2001, the question arises whether German teacher training has an impact on this performance. This publication is based on a systematic review which deals with German-language publications of various PISA-relevant areas within…

This investigation explored a learning community approach to professional development (PD) specifically catered to science teacher educators. It was designed to bolster faculty collaboration, help participants learn about new research relevant to teacher development, and share effective teaching strategies. Forty-four science teacher educators…

Purpose: Awareness of the interaction between science, technology, society, and environment (STSE) is seen as important in life in the modern world. Therefore, the present study aimed to examine the science teacher candidates' views on relations between science, technology, society, and environment. Research Methods: In this research, which used…

Analysing graphs, formulating covariational relationships, and hypothesizing systems' behaviour have emerged as frequent objectives of contemporary research in physics education. As such, these studies aim to help students achieve these objectives. While a consensus has been reached on the cognitive benefits of emphasizing the structural domain of…

Newton's third law is one of the most important concepts learned early in introductory mechanics courses; however, ample studies have documented a wide range of students' misconceptions and fragmented understandings of this concept that are difficult to change through traditional instruction. This research develops a conceptual framework model to…

The present study examines the pedagogical use of reading aloud of science trade books as an effective tool for teaching nature of science (NOS) to elementary students. To this end, we explore elementary teachers' and students' dialogic negotiation of NOS during interactive science read-alouds, as well as potential interactions between their…

High school students need more comprehensive scientific inquiry learning instruction through research ethics education. Yet, this topic is often overlooked in the science curriculum. To collect basic data to guide research ethics education for high school students, this study documents the kinds of research misconduct students commit, the contexts…

In considering the current COVID-19 pandemic as a moment of reflection on a wide variety of issues, this paper discusses the need to rethink the curriculum, in regard to its priorities and in the context of education for sustainability. It does so by revisiting some ideas that have received, or have begun to receive, attention in the field of…

This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

This study aimed to develop, implement, and evaluate argumentation-based inquiry teaching practices to train qualified science teachers. In this context, first, practices in argument-based inquiry were developed to have highly qualified individuals with cognitive flexibility; the ability to look at happening from divergent perspectives and…
