While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

One of the main topics of elementary physics is the idea that every material is composed of "little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one other." These particles could be atoms or molecules. Atoms are the smallest part into…

Objective: Prephonatory vocal fold angle trajectories may supply useful information about the laryngeal system but were examined in previous studies using sigmoidal curves fit to data collected at 30 frames per second (fps). Here, high-speed videoendoscopy (HSV) was used to investigate the impacts of video frame rate and sigmoidal fitting strategy…

"FORE!" Those four letters are often the only thing that alerts spectators attending golf tournaments of danger heading their way. With professional golfers swinging the golf club at upwards of 120 mph, sending the ball an average of 295 yards (Wilco, 2018), and with professional long drive competitors swinging up to 150 mph, a small…

The article presents the results of an experimental study on the motion of a neodymium magnet on an inclined duralumin plate. During experiments, the time of motion was measured, and the steady-state velocity of the magnet motion was determined. To measure the time, a robotic set was used, which made it possible to measure the time of the motion…

Oscillatory motion with damping proportional to the velocity is part of all upper-class physics courses and some introductory courses; however, the emphasis is primarily on the free amplitude decay. Microelectromechanical (MEMs) accelerometers allow the acceleration to be directly measured and the velocity and displacement to be derived from it.…

The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…

This work is inspired by a recent article in a German newspaper about the question of whether a 360 degree turn on an ordinary swing, that is, a seat suspended by chains, is possible. Although the author correctly negates the question, his remarks about the trajectory of the rocking person remain imprecise. Thus, we direct our attention to cases…

Early childhood educators (ECEs) greatly influence young children's physical activity and sedentary behaviors in childcare and psychosocial factors have been found to influence their teaching practices in this environment. This study sought to determine which personal and professional characteristics predicted ECEs' self-efficacy, behavioral…

In this research, it was aimed to analyze the problem solving strategies used during solving problems related to constant speed and constant acceleration motion, which are often used in graphs, according to the presentation of the problem (text and graph). The research was carried out with 119 students studying in the 11th grade. In the research…

Previous psychological, neuroscientific, and educational research indicates that a focus on individual haptic modes of learning (touch, body movement, gesture, tracing), and on the development of emerging mathematical and scientific drawing, can enhance children's learning in mathematics and science. However, most of these studies have focused on…

Academic underachievement of students from disadvantaged backgrounds is an ongoing problem for Australian schooling. Schools serving these communities face profound challenges in meeting their students' educational needs. "Creative and Embodied" approaches draw on pedagogical practices inherent in Health and Physical Education and the…

In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…

The term "functional play" is used widely and variably in serving young children who have developmental delays, affecting its use in research and practice. It also is confused with play as a functional goal. We reviewed studies that used the term. Of 146 reports, less than half included a definition. We organized those with definitions…

Technological, Pedagogical, and Content Knowledge (TPACK) can collaborate with the Science Technology Engineering Art Mathematics (STEAM) approach. STEAM is also essential for students to improve their ability and skills to operate and produce science and technology-based products, supported by the TPACK abilities of educators to develop quality…
