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.…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

The separation of suspensions and immiscible liquids by the laboratory centrifuge is widely used in such fields as chemistry, biology, biochemistry, and clinical medicine. In this paper, an Arduino-based microcentrifuge was fabricated using a computer DVD (digital versatile disc) drive. The hardware part consisted of inexpensive mechanical and…

Purpose: Knowing the students' readiness for the fourth industrial revolution (4IR) is essential to producing competent, knowledgeable and skilled graduates who can contribute to the skilled workforce in the country. This will assist the Higher Education Institutions (HEIs) to ensure that their graduates own skill sets needed to work in the 4IR…

The researchers examined the relationship between informal digital gameplay and learner profiles in two Japanese private universities. Seventy-eight participants responded to 59 items on a digital questionnaire that consisted of four sections: 1) Learner Profiles, 2) Digital Game Usage, 3) Open-Responses, and 4) Demographics. The results of the…

Picture students huddled around a 3D printer in a middle school classroom. They gaze at the object being printed, and exclamations of, "Where is that flag from?" "What does that symbol mean?" and "Oh; I didn't think of that!" can be heard. These examples of observation, curiosity, and critical thinking are the elusive…

This study examines the integration of virtual reality (VR) information technology in the teaching of systems of linear equations in three variables in a high school mathematics class. More broadly, the study investigates the effectiveness of digital teaching with respect to the learning process. The study tests two auxiliary teaching systems: a…

Augmented Reality (AR) is a technology that has benefited from the massification of computational devices, putting it in the focus of researchers as a novel teaching aid in engineering. For this very reason, a great amount of information about AR in engineering education is emerging constantly. To synthesize the information, a Systematic…

A flexible and modular peptide modeling set was designed using freely available software tools. The set consists of space-filling models of all 20 naturally occurring amino acid side chains and a modular kit for constructing peptides employing C-alpha carbons and amide bond groups. Connectors that allow free rotation about phi and psi angles on…

This article explores the history of digital testing technology. Using an organisation that pioneered the use of international large-scale assessments -- the International Association for the Evaluation of Educational Achievement (IEA) -- I discuss the role of computers, punched cards, answer cards and scanning machines as an example of…

New technologies are being developed every day. Many of these may not make it into the curriculum for technology and engineering students. For those that do, there may be quite a delay between the time the technology is introduced at an industrial scale and when the technology is developed at a relatively low cost and small scale needed to…

The ability of rural entrepreneurs to cope with the COVID-19 pandemic greatly depends on their knowledge of Information and Communication Technology (ICT) to support online business. In this study, online surveys were conducted to assess the readiness and acceptance of rural entrepreneurs in adopting to the pandemic using the available…

The paper addresses concept formation processes of a student in the field of geometry. More precisely, the paper deals with the question of how to assist a student in a mathematical concept formation process -- in the context of area calculations in triangles -- with a specially designed learning environment based on the usage of 3D printed…

3D printing is an emerging educational technology that is said to prepare learners for a more technologically designed world. In this review, 3D printing studies are analyzed to identify the dominant theoretical approaches and learning outcomes associated with 3D printing in education. Five theories are identified, including situated learning…

There is a large amount of research that indicates that the use of 3DMP in STEM education improves students' knowledge, motivation, and participation in the learning process. Nevertheless, despite the existing attempts to market 3DMP in education, its adoption in schools remains low. A number of studies with teachers in secondary schools and…
