Aoki, Hiroki; Demura, Shin-ichi; Takahashi, Kenji; Hirai, Hiroshi – World Journal of Education, 2021
Recently, to evaluate dynamic balance ability, a stipulated tempo step test has been developed, and a step error between tempo and contact time of feet has been used as an evaluation variable. The step error, postural sway, and their relationships may differ between the slow tempo (40 bpm) and fast tempo (120 bpm). This study aimed to examine the…

Wadhwa, Ajay – Physics Education, 2021
We have investigated the motion of water flow through glass tubes of different shapes by calculating the value of the Reynolds number denoted as Re. We know that at a given flow rate the value of Re determines the type of flow being classified as laminar, transitional or tubulent. The dependence of Re in different configurations of glass tubes as…

Yanrou Wen; Jiabei Lin; Yue Ming; Junpeng Zhang; Xianqiu Wu; Lei Bao; Keke Yu; Yang Xiao – Physical Review Physics Education Research, 2024
Misconceptions coexisting with scientific understanding pose significant challenges in physics education. Inhibitory control may enable individuals to overcome interference from misconceptions. However, discerning the role of inhibitory control becomes intricate when the saliency of scientific- and misconception-related features varies in a…

Blanco, Philip – Physics Teacher, 2020
A rocket in free space accelerates from rest by continuously expelling fuel; as its speed increases, its mass decreases. At what speed (and remaining mass) does the rocket carry maximum momentum? Maximum kinetic energy? The answers provide insights into the dynamics of variable-mass systems, and have applications to planetary defense that are…

Sanders, James C. – Physics Teacher, 2020
The ballistic pendulum apparatus is a fairly ubiquitous element of the introductory physics laboratory, as the pendulum and launcher gun can be used together or independently to demonstrate a variety of concepts from conservation laws to projectile motion to the motion of a physical pendulum. In this work, we control the launch speed of the gun to…

Grant, Chris; Beach, Tyson A. C.; Hogg-Johnson, Sheilah; Chivers, Michael; Howarth, Samuel J. – Measurement in Physical Education and Exercise Science, 2020
This study evaluated whether real-time applied load feedback and a predefined applied load limit improved inter-session reliability and measurement error of passive glenohumeral rotation range-of-motion measurements. Twenty-one male recreational overhead athletes completed two data collection sessions, approximately 1-week apart. Measurements of…

Frodyma, Marc – Physics Teacher, 2020
Students have difficulty bridging the conceptual gap between Newtonian and relativistic physics, and, consequently, the teaching of special relativity has been discussed extensively in the literature. A comprehensive list of such references is too large to include, but a brief list is given. In this paper, the author presents several exercises,…

Horsch, Georgios M. – Physics Teacher, 2020
One of the easily accessible results in elementary fluid mechanics is the so-called Torricelli's theorem (or law), which states that the velocity U[subscript th] of the fluid exiting from an orifice at depth "h" from the free surface of a container filled with fluid, is the same as the velocity of a free-falling body from rest over a…

Kaps, A.; Starmach, F. – Physics Teacher, 2020
Smartphones and their internal sensors offer new options for an experimental access to teach physics at secondary schools and universities. Especially in the field of mechanics, a number of smartphone-based experiments are known illustrating, e.g., linear and pendulum motions as well as rotational motions using the internal MEMS accelerometer and…

Bekaert, Hans; Van Winckel, Hans; Van Dooren, Wim; Steegen, An; De Cock, Mieke – Physical Review Physics Education Research, 2022
We investigated to what extent secondary school students have insight in the apparent motion of the Sun and stars (AMoSS). We used the AMoSS test instrument, which focuses on distinctions between different aspects of the apparent motion of the Sun and stars. It consists of 12 multiple-choice questions accompanied by explanations. We administered…

Gowers, Sophia J. – Journal of Early Childhood Literacy, 2022
This article examines young children's conceptualisation of the images they encounter within the familiar environments of the home and community settings, focusing on case study data from two, 4-year-old children. The data discussed are taken from a study involving a group of children aged 4-5 years. A participatory mapping approach was adopted,…

Tham, Claire; Yeo, Robin; Natarajan, Visshal; Zhang, Tianqin; Chen, Jer-Ming; Krishnaswamy, Lakshminarasimhan; Tan, Da Yang – Physics Teacher, 2022
In this article, we demonstrate the use of a simple pendulum to explore the concepts of kinematics and dynamics. A simple homemade pendulum and a phone-based accelerometer are used to determine, at various points in time, the acceleration of a moving train. The dynamical and kinematics data from the homemade pendulum and the accelerator can then…

Taskin, Ali Kemal – Asian Journal of Education and Training, 2022
In this study, it was aimed to investigate the anaerobic power, static balance, and speed performances of 10-12 years old children doing or not doing sports. In our study, 20 girls between the ages of 10 and 12 doing sports, and 20 girls between the ages of 10 and 12 not doing sports who both live in the city center of Batman voluntarily…

Swarts, Pieter – Perspectives in Education, 2022
There is a lack of knowledge about how embodied educational practices can be used to challenge and problematise traditional Life Orientation teaching approaches that normally result in a lack of learner engagement on socio- environmental challenges. The objective of this small-scale exploratory qualitative study was therefore to establish whether…
