In many introductory-level physics textbooks, the derivation of the formula for the speed of transverse waves in a string is either omitted altogether or presented under physically overly idealized assumptions about the shape of the considered wave pulse and the related velocity and acceleration distributions. In this paper, we derive the named…

The Doppler effect has seen widespread use in the past hundred years. It is used for medical imaging, for measuring speed, temperature, direction, etc, and it makes the spatial relations of motion easy to map. The Doppler effect also allows GPS receivers to measure the speed of a vehicle significantly more accurately than dashboard speedometers.…

Students must actively engage in problem solving to effectively learn in introductory physics courses. However, students often get stuck and are not able to make progress when solving problems outside of their current ability, particularly when one-on-one tutoring and instructor office hours are a limited resource. One effective technique consists…

The purpose of this paper is to address the most significant contributions of pedagogical content knowledge (PCK) involved in teaching physics. Most studies have observed the characterizations of PCK via specific content in the lower secondary and upper secondary curricula. Here, we present a number of studies that show evidence for the…

Item banking involves tests being constructed by selecting from a bank of pre-written questions. There are various examples of multiple-choice tests where item banking is used, but few examples involving other question types. This research explored the use of banking with structured questions. Three question writers were asked to construct…

Many researchers have suggested that incorporating history and philosophy of science in the science curriculum can be helpful for students' understanding of scientific concepts and effective for developing their scientific thinking. Recently, in this context, there have been studies on historical controversies which show that history of science…

The purpose of this study was to investigate the effects of the flipped classroom on optimizing students' motivation and understanding of medical physics concepts. This approach transfers teacher-fronted lessons out of class to be prepared by students at home and utilizes their class time for discussion and practice. The sample included 123 female…

The oscillating atmospheric CO[subscript 2] concentrations at Mauna Loa, on the island of Hawaii, Hawaii, United States of America, are Fourier transformed in order to extract the period of oscillations. Also well-known as the Keeling curve, CO[subscript 2] concentrations (in time series) at Mauna Loa oscillate in direct association with seasonal…

Twenty-first century classrooms have come with a lot of changes in instructional delivery at various levels of education. However, most lecturers in Nigerian universities still adopt the traditional method of instruction not minding the demands of the twenty-first century classrooms. As a result of this, there is a dearth of empirical evidence on…

Watching over a coffee maker in operation, and designing a simple experiment using it, invokes familiar and unfamiliar physical phenomena and techniques involving calorimetry and heat transfer.

Purpose: Motor outputs are governed by dynamics organized around stable states and spontaneous transitions: we seek to investigate the swimmers' motor behavior flexibility as a function of speed and aquatic environment manipulations. Method: Eight elite male swimmers partook an eight-level incremental test (4% increment from 76% to 104% of their…

The term "Classroom Proxemics" refers to how teachers and students use classroom space, and the impact of this and the spatial design on learning and teaching. This study addresses the divide between, on the one hand, substantial work on proxemics based on classroom observations and, on the other hand, emerging work to design automated…

This paper aims to critically frame the successes and failings of scientific conferences designed for underrepresented undergraduate physics students as counterspaces in physics. The beginning of the paper outlines the necessity of these counterspaces' existence as evidenced by the literature. We apply a critical lens to the experiences of…

This study established whether 12 South African secondary school physics students had incorrect conceptions of basic magnetism and if they had, to what extent they consistently applied such conceptions. Different scenarios in the form of thought experiments were presented in a clinical interview approach. A complex systems perspective underpinned…

Despite decades of research into the gender disparity in physics education and physics practice, the underrepresentation of women in physics persists today. In physics education research, this gender disparity has been constructed as problematic, and numerous approaches from a variety of perspectives have been taken to both research and address…
