This article describes a simple setup of electrospinning using widely available resources. The Arduino board, an electronic platform that is commonly accessible was adapted for a controller. Specifically, recycled parts consisting of plastic gears and a lipstick case were incorporated for the construction of a syringe pump. A cheap DC-DC converter…

An organic solar cell fabrication kit has been developed for demonstration in both undergraduate teaching classes and high school laboratories to promote the growing field of renewable energy and to facilitate empirical comprehension of solar technology. The laboratory focuses on fabricating organic photovoltaics (solar cells) and testing the…

Semiconductor devices, usually made from silicon wafers, are present in the electronic gadgets that we use on a daily basis. In an introductory physics class, the textbook usually devotes a few pages to these devices and moves on. As a result, students may readily forget the material or fail to see how it relates to their lives. A solution is to…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] We present the pedagogical design and implementation of "ESSENCe": Experimental problem solving using Staging, Scaffolding, Embedded information sources, iNstruments, and Collaboration. Research in experimental physics requires…

Many types of batteries power an ever-growing number of devices. Electrochemical devices like batteries and fuel cells can, in principle, exceed Carnot efficiency for energy conversion. In this novel laboratory experiment, students explore the partitioning of the enthalpy change of a battery's electrochemical reaction between useful electrical…

Scanning probe-based microscopes (SPMs) are widely used in biology, chemistry, materials science, and physics to image and manipulate matter on the nanoscale. Unfortunately, high school and university departments lack expensive SPM tools and materials microscopy activities to educate a large number of students in this vital SPM imaging technique.…

A series of hands-on experiments including the synthesis and application of flexible, conductive silver-nanopaste were designed to gain knowledge of conductive soft nanomaterial and the synthesis and the application of silver nanopaste (Ag nanopaste). The aim of this laboratory experiment is to provide undergraduate/graduate students an…

Contribution: A didactic methodology, based on analytical expressions and experimental validation, to describe the process of abrupt current interruption in a series RL circuit, that considers real passive components and uses a toggle switch as disconnecting device. Background: In undergraduate courses, circuits adopted in transient analysis…

Despite the importance of physics practical work in higher education, its implementation is often hampered by various constraints and problems. Technology, such as learning management systems (LMS) and mobile learning, can offer solutions to some of these problems and enrich students' learning experiences. Therefore, this research proposes a model…

In an era where technology is being used more and more in daily life, the potential and effective use of technology is becoming increasingly vital in education. Engineering education necessitates the use of technology to assist students in understanding abstract concepts and principles. Augmented reality (AR) is a technology that can be used to…

In this research, After I have realized some technological applications in the course of general physics laboratory II of the science teacher program, this research aims to examine the effects of the students' attitudes towards technology and the information of the communication technology (ICT) with the mixed method. For this application, after…

Laboratory tasks often focus on mechanical procedures leaving limited time and opportunities for students to build conceptual knowledge. We investigate to what extent introducing simulation tasks to preparation work can enable students to build their conceptual knowledge. We surveyed two cohorts of students taking an electronics module. Laboratory…

In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are that students will never have the opportunity to work with one. A hydrogen electrode should be a device readily available at the…

The ability to develop, use, and refine models of experimental systems is a nationally recognized learning outcome for undergraduate physics lab courses. However, no assessments of students' model-based reasoning exist for upper-division labs. This study is the first step toward development of modeling assessments for optics and electronics labs.…

An undergraduate electrical conductivity measurement experiment in a physical chemistry lab and basic fitting procedures are presented that allow a characterization of micellar system of hexadecyltrimethylammonium bromide (cetyltrimethylammonium bromide, CTAB) in binary mixture of water and acetonitrile (ACN) as a cosolvent (10%, v/v) at 30.0 °C.…
