Autism spectrum disorder is a pervasive neurodevelopmental disorder that has been linked to a range of perceptual processing alterations, including hypo- and hyperresponsiveness to sensory stimulation. A recently proposed theory that attempts to account for these symptoms, states that autistic individuals have a decreased ability to anticipate…

The objective of this study is to assess the impact of deceleration training method on improving dynamic balance skills of young soccer players in comparison with the conventional training methods. This study included 26 young soccer players (mean age: 13.54±1.48, height: 154.98±12.44, weight: 46.16±11.06, Body Mass Index 18.96±2.21 kg/m2 , fat…

The objective of the study is to assess the effects of Differential Learning (DL) approach on learning the tennis stroke techniques, retention of skills, and improving the mobility time of young tennis player candidates in comparison with the traditional teaching methods and, accordingly, to present the teaching methods that are suitable for a…

Research-based assessment instruments (RBAIs) are ubiquitous throughout both physics instruction and physics education research. The vast majority of analyses involving student responses to RBAI questions have focused on whether or not a student selects correct answers and using correctness to measure growth. This approach often undervalues the…

The aim of this study is to explore how children bring together motor processes, language and perception when embodying emotional states (Condition 1) versus factual events (Condition 2) through the story characters of 'Little Red Riding Hood'. Children aged 3-4 years (N = 33) were observed while enacting each story-character through…

We report the findings of an empirical study that investigated whether the source of data--firsthand or secondhand data gained from lab work experiments--has an influence on students' learning outcomes. Results indicate that students' choice of a correct or incorrect hypothesis for a pendulum lab experiment on the influence of the mass of the bob…

This research aims to develop a falling chain experiment apparatus using kitchen scales and digital cameras (smartphones). Digital cameras were used to observe and record changes in the mass of falling chains measured using kitchen scales. Video recordings from observations of falling chain masses were analysed using Tracker 5.1.1 software. The…

Name signs are based on descriptions, initialization, and loan translations. Nyst and Baker (2003) have found crosslinguistic similarities in the phonology of name signs, such as a preference for one-handed signs and for the head location. Studying Kata Kolok (KK), a rural sign language without indigenous fingerspelling, strongly suggests that…

This article discusses a study of the relationship between movements of the head and the torso in Finnish Sign Language (FinSL). It describes the differences and similarities in the articulation of these two body parts in FinSL narratives, and discusses the status and relationship of the head and the torso as articulators in sign languages. The…

Background: When developing walking programmes for improving health in adults with Down syndrome (DS), physical activity professionals are in need of an equation for predicting energy expenditure. We therefore developed and cross-validated an equation for predicting the rate of oxygen uptake (VO[subscript 2]; an index of energy expenditure) for…

One way to ease the solution of physics problems is to visualize the situation. However, by visualization we do not mean the pictorial representation of the problem. Instead, we mean a sketch for the solution of the problem. In this paper a new approach to solving physics problems, based on decomposing the problem into with and without gravity, is…

The classic demonstration illustrating Lenz's law by dropping a magnet through a copper pipe is presented using household aluminum foil right out of the box. Then comes the surprise. The teacher presents an aluminum foil cylinder with a missing lengthwise slice (cut before class). Will the demonstration still work? Students are amazed at the…

Physics textbook authors commonly introduce the concept of weightlessness (apparent or real) through a "thought experiment" in which a person weighs herself or himself in an elevator. When the elevator falls freely, the spring balance should show zero weight. There is an unresolved controversy about how this "zero reading"…

Students in an upper-level physical chemistry course used a polarimeter to measure the molar optical rotation of different optically active amino acids to confirm the Clough, Lutz, and Jirgensons (CLJ) rule. This rule states that an amino acid is in the l-configuration if the molar optical rotation becomes more positive upon the addition of acid…

Start speed, acceleration, and speed performance are critical factors affecting directly football player's performance. The aim of our study was to examine the relationship among these three abilities. 79 football players voluntarily participated in the study (height: 177,96 ± 5,4cm; weight 73,72 ± 7,85kg; training age: 10,59 ± 2,94 years; age:…
