In this study, we propose a novel and direct method of determining the focal length of a converging or diverging lens using a smartphone. The standard optical sensor used in modern smartphone cameras is an active-pixel sensor called the complementary metal-oxide-semiconductor (CMOS). The CMOS is covered by an assembly of five to seven camera…

Military culture involving, for example, a lack of autonomy and hierarchical structure, has hindered Taiwanese military students' English learning and increased the difficulty to obtaining learning materials. In particular, English for specific purposes (ESP) vocabulary learning is difficult for military students when English is used as a medium…

Mobile performance support systems (MPSS) involve the use of handheld and wearable devices to assist workers to complete job tasks that are not tied to a fixed location. This paper acknowledges MPSS as an emerging human performance technology (HPT) intervention and distinguishes the differences between mobile learning and MPSS. MPSS focuses on…

Contribution: The evaluation of analog-to-digital conversion methods constitutes a key component of an Instrumentation course. This study introduces an affordable educational platform based on Arduino UNO board designed for teaching analog-to-digital conversion concepts, supported by virtual instruments (VIs). Background: ADCs are electronic…

In high school, LC(R)-circuits are an integral component of physics education. We propose a new setup for exploring those circuits utilizing the magnetic field sensor of a smartphone in combination with the application phyphox, which reads and displays sensor input. Coils with high inductance and low resistance generate low frequency oscillations…

Introduction: Electronic Bluetooth scales (e-scales) may be useful for remote weight assessment. This study analyzed predictors of engagement with e-scales and feasibility for remote weight assessment. Method: Due to COVID-19 restrictions, participants (n = 150, 100% African American, 79% female, average age 48.2 ± 10.6 years) in an ongoing trial…

Your body is not a point particle. The nature and direction of the forces counteracting gravity influence your experience of uniform rectilinear motion--as does your own orientation in relation to the force of gravity. Sensors in smartphones or other devices can capture these forces, and help establish a connection between the personal experience…

Youth want workforce policies and programs that reflect their unique needs. If policymakers listen, they will create more inclusive opportunities that benefit communities, local businesses, and youth themselves. Jobs for the Future (JFF) held a series of focus groups with young people ages 16 to 24 focused on their career aspirations and…

Early studies evaluating the relative preference for leisure compared with edible items suggested that, for most participants (>80%), edible items are more preferred than leisure items. Recent studies suggest more variability in the percentage of participants with this preference. The rationale for this variability could be sampling, setting,…

Understanding Physics is a great end in itself, but is also crucial to keep pace with developments in modern technology. Wireless power transfer, known to many only as a means to charge electric toothbrushes, will soon be commonplace in charging phones, electric cars and implanted medical devices. This article outlines how to produce and use a…

This paper proposes a novel education system for learning electronic circuit construction involving soldering on a universal circuit-board. This system enables a student to efficiently design the layout of circuit components on a circuit board and helps the student securely construct the circuit by soldering the circuit components in accordance…

The spatial dependence of magnetic fields in simple configurations is a common topic in introductory electromagnetism lessons, both in high school and in university courses. In typical experiments, magnetic fields and distances are obtained taking point-by-point values using a Hall sensor and a ruler, respectively. Here, we show how to take…

We present a method for the teaching of Electronics, defined as the scientific discipline that studies the movement and behavior of electrons in semiconductor materials and in vacuum. Electronics can be considered as a science with a solid physical foundation. Within the field of Electronics there are different disciplines, some of them can be…

The purpose of the study is to determine the effect of augmented reality applications on the learning of engineering students in their professional courses. The objective of the study is to ensure that augmented reality technologies, which are among the most important technologies of today, are used in educational settings. The other important…

The main challenges commonly associated with acquiring practical network engineering skills are the requirements for access to specialised and up-to-date network equipment, as well as the high costs associated with obtaining and maintaining this equipment. The PT Anywhere initiative addresses these challenges by offering a mobile environment for…
