Virtual laboratories of electromagnetism for education in engineering: A perception

Abstract

The influence of virtual tools as didactic means towards the study of electromagnetism phenomena takes greater relevance every day at the Universidad del Magdalena due to the inclusion of a visual and dynamic element beyond the reading of physical text books and even the development of laboratories real electromagnetism. This article shows a very positive perception on the part of the engineering students regarding the advanced virtual laboratories of electromagnetism, influencing the learning of physical concepts and the development of cognitive competences. Studentś understanding of the concepts of physics in the domain of electromagnetic physics was evaluated in a pre- and post-test design involving 60 participants assigned to four experimental groups and 30 participants assigned to the control group. There were two experimental conditions, namely, experimentation with manipulation of real material, experimentation with virtual manipulation, as well as a condition of control (ie, traditional instruction with no virtual experimentation). Conceptual tests were administered to assess student’s comprehension before, during and after the application of the virtual laboratories. The analyzes revealed that even though the two experimental conditions promote the conceptualization and correct interpretations of the student’s physical concepts in the domain of electromagnetism better than in the control group as expected; we see that, the use of the virtual tool obtains a greater acceptance as this study shows.

Use of Arduino Microcontroller and Proteus Software in Physics Lesson in Review of Mathematics Ability and Critical Thinking Skills

“…This is because the Digital Electronics material is of high complexity and contains quite a lot of mathematical concepts, so a fairly high mathematical ability is needed, thus students who have high mathematical abilities will more easily and quickly understand Digital Electronics material and apply it to problems physics compared to students who have the low mathematical ability. This is in line with research conducted (González et al 2019) that in physics, mathematics plays a major role. In addition to its ability to solve physics problems from simple to more complex, mathematics is very helpful in one's reasoning in exploring the intricacies of physics which require a quite high reasoning.…”

Development of Density Meter Learning Media Using Arduino Uno to Improve Critical Thinking Abilities

“…The Arduino Uno microcontroller gives students the freedom to design a wide variety of projects, from simple to complex. This design process encourages creative thinking skills in creating innovative solutions to given problems or tasks (González et al, 2019); Decision Making. In developing a project with the Arduino Uno, students need to make various decisions, such as component choices, design approaches, and programming strategies.…”

El trabajo experimental en la enseñanza de la Física en tiempos de pandemia mediante el uso de la aplicación II Ley de Newton en la UNED de Costa Rica

“…Por otra parte, es importante no omitir que parte de los retos que se asumen con este tipo de recursos como son los LV y propiamente la aplicación de la II Ley de Newton es que los docentes puedan acompañar más en el uso de los LV (González, Escobar, Beltrán, García & Hoz, 2019). En este caso particular, la medida más baja con el 2.5 resaltó cómo los estudiantes, aun cuando el recurso tiene muchas ventajas requieren de una guía para comprender en su totalidad el uso de estos.…”
