Physics, even though it is guided by simple principles, tends for many topics to be obscured in the mathematics redundancy. MATLAB®, as interactive software for computer algebra, has already had an important impact on the way physics is taught by educators. It has also had a substantial impact on the way research is performed by students to…

In this study, we developed an online problem-based learning (PBL) module for the Impulsive Force subtopic of Physics Form Four and studied its perceived usability among Physics trainee teachers. The research design of this study is developmental research and a quantitative study using a survey approach. The module was developed according to five…

Embedding physics problems in real-world settings--here termed contextualized physics problems (CPPs)--is widely believed to foster students' interest, motivation, and learning. However, firm evidence for this claim remains scarce. To explore this issue, we surveyed 868 secondary students and 154 teachers to examine their attitudes toward CPP and…

Socioeconomic growth is largely influenced by education, which promotes equality and creativity. Recent trends show a sharp drop in high school graduates' enthusiasm in pursuing the natural sciences, particularly physics, despite past and present dedications to high-quality education. With an emphasis on physics, this study explores the choices…

This study systematically explores instructional strategies that enhance students' problem-solving skills in physics through a systematic literature review. A systematic search and screening process was followed, and findings were synthesized using a weighted narrative approach due to methodological heterogeneity. A total of 118 articles were…

The introductory phase of studying physics poses a wide range of challenging problems to new students. One of them is learning physics on a new, more abstract and highly mathematised level, at high speed, in a lowly regulated learning environment. While several German universities have taken action to mitigate these problems, much knowledge about…

The cosine theorem is used in solving triangulation problems and in physics when solving problems of addition of unidirectional oscillations. However, this theorem is used only for the analytical calculation of triangles or when solving problems of adding two oscillations. Here we propose a generalization of the cosine theorem for the case of…

Despite the fact that the free-body diagram is the most common method of representing forces in physics education, alternative means have been proposed over the years. Here we present a summary of the proposals found in the literature on physics education. We aim to discuss the pros and cons of these proposals, examine their degree of iconicity,…

Purpose: Given the established linear relationship between neck surface vibration magnitude and mean subglottal pressure (Ps) in vocally healthy speakers, the purpose of this study was to better understand the impact of the presence of a voice disorder on this baseline relationship. Method: Data were obtained from participants with voice disorders…

Objective: The aims of this study were to test the hypothesis that greater supraglottic compression (anteroposterior or lateral) correlates with higher subglottic pressure (SGP) and to develop a classification of muscle tension dysphonia (MTD), based on the degree of supraglottic compression during speech. Method: A prospective, cross-sectional…

Previous generations of physics students learned how common machines work, as evidenced by their textbook illustrations. Such understanding of machines that daily life depends on seems to be evaporating. In response, for two decades I have conducted an introductory physics "engine cadaver lab." It offers opportunities for hands-on…

The distant magnetic field of a magnetic dipole is usually derived via the magnetic vector potential and substantial vector calculus. This paper presents an alternate proof that is less mathematically intensive, and that ties together various problem-solving tricks (the principle of virtual work, observation that only instantaneous quantities…

There are many phenomena, interesting, simple experiments and effects, that await their in-depth explanation from the point of view of physics. Some of them have been well known for a long time but their numbers are increasing, especially with the introduction of new technology in everyday life. In this paper we consider a simple experiment that…

In a recent submission to "The Physics Teacher," we related how trigonometric identities can be used to find the extremes of several functions in order to solve some standard physics problems that would usually be considered to require calculus. In this work, the functions to be examined are polynomials, which suggests the utilization of…

We have demonstrated both interference and diffraction of a pseudo-double slit using two glass plates with a width and a length of about 5 cm and a thickness of about 5 mm. The plates are attached at the upper and lower ends with Scotch tape of about 0.1 to 0.3 mm between the plates. By adjusting the angle between the two plates, we are able to…
