This paper describes a pictorial approach to Lenz's law that involves following four steps and drawing three pictures to determine the direction of the current induced by a changing magnetic flux. Lenz's law accompanies Faraday's law, stating that, for a closed conducting loop, the induced emf (electromotive force) created by a changing magnetic…

The purpose of this study was to describe the accelerometry-based characteristics of overall sedentary behavior (SB) and sitting among adults under free-living conditions. Thirty-six (mean age 47.6 years) volunteers carried a waist-worn accelerometer for =4 days with data =600 min/d during 14 consecutive days. A machine learning (ML) based method…

A video is taken of a road-sign mirage from the passenger seat in a car traveling at constant speed on a highway. The video spans the duration of seeing the mirage of the sign, viewing the vanishing of the mirage as the car approaches, and passing the road sign. The mirage angle, defined as the angle with respect to the horizontal at the moment…

The aim of this research was to investigate the effect of vibration applications on muscle strength and balance. As the subjects to the research, nineteen male sport science students (age: 21.45±2.16 years, height: 177.55±7.24 cm, body mass: 71.62±11.02 kg) voluntarily participated in the study. The students were exposed to vibration in squat…

Studies comparing the instructional effectiveness of dynamic versus static visualizations have produced mixed results. In this work, we investigated whether gender imbalance in the participant samples of these studies may have contributed to the mixed results. We conducted a meta-analysis of randomized experiments in which groups of students…

Purpose: Vertical jump is a common test to measure impulsive ability in soccer; however, limited normative data have been published on young soccer players from vertical jump measurements on a force platform. The purpose of this study was to provide normative values for three chronological age groups of male junior soccer players (U16, U17 and,…

The research orientation of the Department of technics, Faculty of Education, University of Hradec Kralove focuses on finding new ways for development of polytechnic and science education. The research is motivated by the fact that children's interest in technical and science subjects is decreasing in recent years in the Czech Republic. The…

Black creative educational experiences (BCEEs) are participatory, performative cultural experiences created by or for students, centering Black artistic expression, aesthetics, and engagement. Using African-centered frameworks, we provide a methodological guide for examining BCEEs in education research, which includes centering Black "ways of…

Chinese opera performance proceedings can be divided into two types. The first is 'visible proceedings', which can be directly seen and heard in the performance, and the second is 'invisible proceedings', which arrange the story and performance of the opera using procedural thinking. The research methods of this study were mainly used to analyze…

Developing self-regulation at an early age is important for children's success in school and in life. Self-regulation involves the ability to remember instructions, shift attention from one thing to another, and reduce the intensity and frequency of impulsive emotions and behaviors. "Red Light, Purple Light" is a preschool program that…

This classroom technology pilot explored the ways in which three different tools yielded insights into instructors' and students' use of physical classroom space in a higher education environment. The tools of interest were a ceiling heatmap camera from Panasonic, small ultrawideband movement trackers from Pozyx, and an audio sensor from TSI. The…

This study investigated the effect of the metacognitive instruction in which students' epistemic cognitions were explicitly addressed, on tenth-grade students' conceptual understandings regarding force and motion. The participants of the study included 107 (49 female, 58 male) tenth-grade students at two public high schools. A quasi-experimental…

The experiment that we present in this paper explores the teaching of Galilean motion principles observed in different reference frames, in an astronomical context. All grade 10 students in a French high school (the lycée Condorcet, Val de Marne) participated in two successive teaching-learning sessions, designed within the theoretical framework…

A Science, Technology, Engineering and Mathematics (STEM) tool is proposed in this manuscript; which consists of an interactive, simple and low-cost computer based simulation and game, with the aim of easing the teaching/learning process regarding the physics concept of projectile motion. The novelty of this proposal relies on the use of a…

The study tests the efficacy of a new sort of digital picture book. It includes camera movements to guide children's visual attention through the pictures and the possibility to control page-turning and the pace at which the camera moves through pictures. There were 56 participants (M[subscript age] = 60.34 months, SD = 6.24) randomly assigned to…
