Purpose: Given the established linear relationship between neck surface vibration magnitude and mean subglottal pressure (Ps) in vocally healthy speakers, the purpose of this study was to better understand the impact of the presence of a voice disorder on this baseline relationship. Method: Data were obtained from participants with voice disorders…

Teaching through discrepant event activities increases student interest in science. In this article, I will introduce a well-known 19th century demonstration, the Tissandier experiment, to stimulate curiosity among students learning the concept of inertia. In this demonstration, a hard object (e.g. a wooden rod) placed on fragile supports is…

Recent years have seen an immense development in the field of X Reality (augmented, virtual, and mixed reality), empowering healthcare, education, and entertainment, and the trend predicts an exponential increase in the upcoming years. Augmented reality is a technology in which real-world environments can be enhanced by adding computer-generated…

An experiment using the volumetric flux of a water stream was used to find the initial velocity of the water as it performs parabolic motion. The trajectories were measured with different initial velocities, comparing the maximum height and range values with the theoretical calculations. The closeness of the measured values to the calculations…

It can be a challenge to come up with simple demonstrations of circular motion and conservation of energy. One such demonstration consists of a large exercise ball, off of which a small solid ball is rolled. The small ball is coated in finger paint so, after an initial push, it rolls nearly without slipping and creates a visible track.

The point particle is an idealized object where rotational and vibrational motion is ignored. Nevertheless, in many cases such degrees of freedom play a significant role. For example, the rotation and vibration of a molecule is an important "reservoir" of its internal energy. The excitation of these types of motion can occur during the…

The image of free-falling bar has been recorded to study the effect of the motion on its observed length. This moving bar image is analysed using the Tracker software to determine its length and the end bar's position. An elongated appearance of the bar has been observed with movement. This effect relies on the speed and the exposure time during…

Background: The potential for using ultrasound by speech and language therapists (SLTs) as an adjunct clinical tool to assess swallowing function has received increased attention during the COVID-19 pandemic, with a recent review highlighting the need for further research on normative data, objective measurement, elicitation protocol and training.…

The aim of this study is to investigate the differences in kinematic parameters of freestyle swimming with respect to young swimmers before and after 3x200 metres (m) performances. Seven male swimmers (mean age: 13.86±0.90; mean height: 164.79±6.89cm; mean mass: 54±5.54kg) participated in this study as volunteers without any injury history. Before…

In this study, we investigated whether the difficulties in body motion (BM) perception may led to deficit in emotion recognition in Autism spectrum disorder (ASD). To this aim, individuals with high-functioning ASD were asked to recognise fearful, happy, and neutral BM depicted as static images or dynamic point-light and full-light displays.…

Newton's laws are essential for understanding causes and description of mechanical motion. Great attention is paid to them during physics education. Unfortunately, many students, not only in high school, but also undergraduates, can recite them but do not understand their essence. Therefore, it is useful to demonstrate different experiments in the…

Autistic individuals are commonly characterized by stereotypical behaviors, which affect their daily life, particularly social aspects. The study aimed to assess the effectiveness of dance movement-based intervention in reducing stereotypical behavior among autistic children. The study used an experimental-based approach, which recruited 30…

This study explored (1) the effect of applying an autocalibration algorithm on accelerometer data analyzed using different signal processing techniques and (2) how these techniques changed the signal composition. Using a dataset of preschoolers (n = 137; 4.31 ± 0.87 years; Actigraph accelerometers (100 Hz) on right hip 24 hours/7 days) the vector…

Background: Recent literature indicates that the trend towards investigating pre-service elementary teachers' conceptual understanding of science concepts they are expected to teach and their command of that content-specific conceptual understanding is gaining momentum in science education. Purpose: The purpose of this study was to investigate…

Whereas previous research has focused on religious education (RE), teachers' religious attitudes, and personal religiosity, no studies to date have examined their experiences or discussion of positionality in a RE setting. The denominational-cooperative model of RE serves as a specific opportunity for such research since common denominational RE…
