Purpose: This study investigated the criterion (analytical and clinical) and construct (divergent) validity of a novel, acoustic-based framework composed of five key components of motor control: Coordination, Consistency, Speed, Precision, and Rate. Method: Acoustic and kinematic analyses were performed on audio recordings from 22 subjects with…

This study examined functions of self-motion and visual cues in updating people's actual headings in multiscale spaces. In an immersive virtual environment, the participants learned objects' locations inside two misaligned rectangular rooms by locomoting within and between the rooms. In each testing trial, the participants locomoted to adopt an…

Sport coaches continue to coach without reference to a conceptualisation of coaching. Indeed, coaching research has been caught in a chasm between process and practice conceptualisations, further widening the application of theory to practice. And coaches are often the protagonists in both of these accounts. Yet, as we will see, this is…

Implementing smartphones with their internal sensors into physics experiments represents a modern, attractive, and authentic approach to improve students' conceptual understanding of physics. In such experiments, smartphones often serve as objects with physical properties and as digital measurement devices to record, display, and analyze…

Echo phonology was originally proposed to account for obligatory coordination of manual and mouth articulations observed in several sign languages. However, previous research into the phenomenon lacks clear criteria for which components of movement can or must be copied when the articulators are so different. Nor is there discussion of which…

Purpose: This study examined the physiological sport-specific demands (total distance, mean velocity, effective game time, and time in five velocity zones) in elite bandy players of offensive and defensive playing positions. Method: Data were collected with 10 Hz GPS-units in the Swedish Elite League during the season 2015/16. Ten male elite bandy…

The question from the title is raised because in almost all introductory physics courses/textbooks the atmospheric pressure has been attributed to the weight of the column of air from a given level in the atmosphere up to its top. "Air is pressing on air." However the same textbooks, in the chapter on the kinetic theory of gases, tell…

Owing to the presence of the Coriolis effect, the rotation of Earth has a multitude of surprising consequences that make the mechanics of the atmosphere or the oceans different from that of a fluid in a container. Since the Coriolis effect also captures the imagination of screenwriters, contributing to the continual exposure of students to bogus…

Ever increasing technological progress opens novel opportunities concerning educational activities, and the ability to use the technology effectively is one of the 21st century's most demanding skills. The Partnership Forum for 21st-Century Skills (P21) states that no organization can achieve satisfying results without using technology and…

Of the many disciplines that rely on calculus, physics is among those with the strongest connections to this branch of mathematics. For instance, the derivative--one of the key notions of calculus--is used to describe velocity and acceleration, which play a central role in mechanics. In post-secondary education, in particular at the college level,…

Computational thinking in the educational environment has awaken a rising interest, having been included as part of the curricula from the very beginnings of education. Programmable robots have become a valuable positive resource in order to succeed in the development of computational thinking, demanding proper training from kindergarten teachers…

Objectives: The aim of the current study was to investigate the robustness of the human movement effect and its stability over time by comparing the effectiveness of dynamic and static presentations on acquisition and retention of a gross motor skill. Methods: One hundred and seven first-year students studying for the certificate in Physical…

This quasi-experimental study was conducted in two secondary schools in a major city in the United Arab Emirates (UAE) to examine the impact of Computer Simulations (CSs) on students' learning of Newton's Second Law of Motion (NSLOM) in grade 11 compared to traditional face-to-face education. The study used Newton's Second Law of Motion…

The oscillations of one mass "m" suspended between two different springs, assuming a friction force proportional to the velocity [minuscule], have been studied. For this purpose, an assembly for this system has been made. The movement of the mass is recorded with a smartphone and analysed with "Tracker." It is obtained that the…

In a 1993 book review, E. Pearlstein asks, "Why don't textbook authors begin their discussion of magnetism by talking about magnets? That's what students have experience with." A similar question can be asked, "Why don't professors have students measure the force between permanent magnets in introductory physics labs?" The…
