In today's digital world, understanding refresh-rate implications on visual perception and energy consumption is crucial. While high refresh rates enhance motion perception and user experience, they also increase energy usage, prompting the need for adaptive solutions like variable refresh rates. This study examines whether users notice or are…

Sensory needs are being recognised as a vital part of learning, development and engagement within the classroom and are being used more often to make education both accessible and fun. To harness the full potential of sensory supports, using these strategies correctly is key! This is the essential guide to using sensory strategies successfully…

This study investigated whether increased attention to the central or peripheral visual field can reduce motion sickness in virtual reality (VR). A recent study found that increased attention to the periphery during vection was correlated with lower self-reported motion sickness susceptibility, which suggests that peripheral attention might be…

A Slinky is a loose helical coil spring and is a well-known educational toy. In this paper a model for a Slinky is presented. The Slinky is represented as a sequence of rigid half coils connected by torsional springs. A range of Slinky configurations in static equilibrium are calculated. Where possible the torsion spring model is compared with the…

The purpose of this article is to revisit the biomechanical concepts of Paul Rolland's scholarship on bowing to provide a new framework of Rolland's underlying bowing principles. First, we discuss how whole body movements help facilitate natural bowing, which can generate better tone efficiently from freedom of movement. Second, we attend to the…

In this article, we introduce the notion of "motion simulation hinge" and discuss its role in mental simulation of previously-experienced motion events and also mental simulation of scientific concepts in terms of motion events. Motion simulation hinge is defined as a static imaginary object or area around which or relative to which a…

This study aimed to analyze the intrasession reliability of the rate of force development (RFD) in different time windows in squat jumps (SJ) performed at different knee starting angles, and identify the relationship of RFD with vertical jump height (VJH). Twenty male volleyball and basketball players participated. Athletes randomly performed SJ…

Modern MEMs gyros/accelerometers allow the angular velocity of pendula to be precisely measured and the angular acceleration to be calculated. For a compound pendulum, "I"[subscript p][umlaut over theta]=-"mga" sin[theta]Ip[umlaut over theta]=-mgasin[theta], where "a" is the distance of the center of mass from the…

Vertical jump height is a widely used variable in sport science and physical education. This narrative review summarizes various numerical methods used to calculate vertical jump height. In force plate technology, the jump height is most commonly calculated using the flight time (FT) or the takeoff velocity (TOV), which provide only the distance…

Difficulties in understanding physics concepts are often experienced by students such as in the material of regular uniform motion. This study aims to describe the mental models of first-year secondary school students on regular straight-line motion. This research utilized a case study method of 167 students at the secondary level with an average…

The ability to adjust movements in response to perturbations is key for an efficient and mature nervous system, which relies on two complementary mechanisms -- feedforward adaptation and feedback control. We examined the developmental trajectory of how children employ these two mechanisms using a previously validated visuomotor rotation task,…

To combat the ever-increasing number of symptoms of ADHD in the classroom, this article suggests a few strategies and a one-week physical activity plan for educators to adopt during the school day. These strategies are easily implemented, requiring no additional equipment, tools or extra time.

Background: Recognizing the relatively few studies that have explored university students' understanding and alternative conceptions in linear and circular motion as well as the relatively few studies that have used 2-dimensional multiple-choice questions (MCQs) in the science education literature, this study set out to contribute to these areas.…

Some researchers suggest difficulties synchronising with a partner could underpin the social differences associated with Autism Spectrum Condition, potentially acting as a marker for autism. Social Motor Synchrony (SMS) is one aspect of synchrony that could augment observational diagnostic procedures. However, the full breadth of literature…

We describe a simple, intuitively appealing interpretation of the observed ellipsoidal shape of the rotating Earth: it is that surface everywhere perpendicular to the net force upon it.
