Earlier research has shown that students have tremendous difficulties with understanding certain aspects of rolling without slipping, such as the zero-velocity at the contact point and plausibility of application of the law of conservation of mechanical energy despite action of the friction force. The aim of this research was to explore whether…

Recent findings in music research are increasingly confirming the embodied nature of music cognition. Assuming that a bodily engagement with music may affect the children's musical meaning formation, we investigated how young children's interaction with music, based on verbal description after listening versus body movement description while…

Purpose: The current study investigated the effect of attention on heaviness perception and its physiological and kinematic contributions. Method: Participants lifted objects that varied in mass and volume while their muscle activity and movement were recorded. Participants were instructed to pay attention to their arm (internal) or the object…

This paper describes the results of a survey administered to members of the American Association of Physics Teachers and the National Earth Science Teachers Association to measure the nature and frequency of the integration of Earth and space science (E&SS) concepts into physics courses, as well as the need and interest of physics teachers to…

The aim of this study is to investigate sixth grade students' academic achievement and their attitudes towards STEM practices applied in the unit of "Force and Motion" of science course book. In the study, experimental research design with randomly selected pre-test post-test groups was employed. The study was conducted with sixth grade…

STEM education is a pedagogical philosophy which aims to draw the interrelationship between science, technology, engineering and mathematics to solve complex problems in real life situations. In order to use STEM education to foster students' learning, the researchers designed STEM activities for middle school students related to the concept of…

The food industry is an important constituent of a country's economy, which provides the population with food. The development of the food industry and the supply of food products to the entire population requires improving food-manufacturing technologies, such as the process for production of extruded poly-cereal food products using…

The phenomenon of lateral inversion is explored in this question. If a clock is viewed in a plane mirror, will the motion be clockwise or anticlockwise?

Most students find real-world examples of harmonic oscillations interesting. Besides, normal and friction forces are the types of concepts in physics that are readily applicable to their everyday life. For instance, we depend on these forces to write, to drive cars, to pick up objects, and even to walk! And yet introductory physics students have…

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…

Simple harmonic motion (SHM) is a common topic for many students to study. Using the free, though versatile, motion tracking software; "Tracker", we can extend the students experience and show that the general equation for SHM does lead to the correct period of a simple pendulum.

Baseball's flirtation with technology began in 2005 when PITCHf/x® by Sportvision started to be installed in major league ballparks. Every stadium had the system operational by 2007. Since then, the trajectories of over six million pitches have been measured to within about half an inch using three 60-Hz video cameras to track the position of the…

In a recent article in this journal, Shakur described an interesting problem where a bullet of mass "m" strikes a block of wood of mass "M" and projects the block upward. The same problem was considered earlier by Cowley et al. and others. The main question of interest is whether the block rises to a greater height if it is…

Resources theory assumes that resource activation is context sensitive, and that an important dimension of context is the question students are answering. The context sensitivity of resource activation has been demonstrated empirically by case studies that show students using different resources to answer questions that are similar in focus. In…

Despite holding wide-ranging experiences with constant velocity and non-zero acceleration, students wrestling with physical science concepts struggle to demarcate the two distinct characteristics of motion. In fact, this prior experience and loose familiarity with associated terminology often act as an obstacle toward a deep and robust…
