This article reports on a new device, called a geyser guide, that allows for quantitative measurements of both bubble sizes and kinetics of foam production in the so-called Diet Coke and Mentos experiment. The device is easily constructed, is made using readily available materials, and allows the experiment to be carried out indoors with no mess.…

This study evaluates the dimensions of fractional-size violin bows in relation to the anthropometric and grip-strength measurements of children and adults. In string education, various methods and devices have been put forward to measure children for the correct violin size, but there is a lack of research regarding the proper bow size. Results…

Purpose: Ultrasound imaging offers a noninvasive adjunct to clinical swallowing assessment. Published reliability of sophisticated ultrasound systems is promising; however, no data exist for reliability using more affordable, pocket-sized devices. This study explored intrarater, interrater, and test-retest reliability of swallowing measures…

Digital gaming has broad appeal globally, with a reported 2.7 billion gamers worldwide. There is significant interest in using games to enhance learning, with 'serious games' being included in classrooms to engage adolescents' learning across a range of domains. A systematic scoping review of serious games used for health promotion with…

We propose an easy experiment that allows students to determine the speed of sound through a simple time-of-flight measurement using two smartphones. The concept of using the sensors in mobile phones for physics experiments has become a well-known option for science teachers. Since these devices are readily available to most students and teachers,…

Our study tried to assess the effect of the Special Movement Education Program on the balance skills of children with intellectual disabilities. We used the experimental design of 23 children with intellectual disabilities between the ages of seven and ten in a special education and rehabilitation center in Burdur, Turkey formed the study group.…

The purpose of this study was to investigate the effects of exergame training which can be conducted on stable floor; at school with smart board and at home with TV screen, on students' balance improvement. 53 students with age average of 10,25[plus or minus]0.504 were voluntarily participated to this research. In this experimental research,…

Some of the subjects have complex concepts, which are currently taught using deductive methods in the first years of University Degree. However, the experience shows the results obtained from students' learning goals were quite low. Therefore, the use of inductive method is a crucial factor to improve students' learning results and re-thinking the…

Electrocardiography (ECG) is one of the most widely used methods in clinical diagnosis. Here we describe an experimental approach that offers hands-on learning of its basic principles. An experimental model that consists of a rubber foil with a low electrical conductivity and a DC power unit is used to simulate the body and the electric dipole of…

Purpose: The purpose of this study was to investigate the effects of tongue-strengthening exercise (TSE) on tongue strength and effortful swallowing pressure in young healthy adults. Method: Thirteen young healthy volunteers (six men, seven women; M[subscript age] = 20.5 ± 0.5 years) performed 8 weeks of isometric TSE 3 days per week. A tongue…

A continuing line of research indicates that focus of attention is perhaps the most important attribute of actively participating in meaningful music listening and a model accounting for these findings has been developed. Music teachers are especially concerned with meaningful listening when having students discern important elements or attributes…

This study presents a between- and within-subjects quasi-experiment that investigated the impact of interactive holographic scenes (virtual environment) on learning sensing technologies such as laser scanners, drones, radiofrequency identification devices, and inertial measurement units. To achieve this, the study assessed students' semester…

Several suggestions for the use of Mobile Phone (MP) sensors in science teaching are found in the literature, and most of them focus on proposing physics experiments that can be conducted with the aid of the sensors that commonly exist in smartphones. The proposed experiments rely on the Bring Your Own Devices (BYOD) approach, that is, students…

Optimization is a component critical to method development. Mathematical modeling of physical phenomena enables an efficient search for the parameters and conditions that optimize methods and systems. Here, optimization of methods in sonoelectrochemistry, electrochemical separations, electrochemical education, and assessment of diabetic status are…

Purpose: This study compares the precision of the electromagnetic articulographs used in speech research: Northern Digital Instruments' Wave and Carstens' AG200, AG500, and AG501 systems. Method: The fluctuation of distances between 3 pairs of sensors attached to a manually rotated device that can position them inside the measurement volumes was…
