3D virtual laboratory for teaching circuit theory — A virtual learning environment (VLE)

The key to succeed in engineering is to master information and the correct use of materials. The learning of the basic concepts of circuit theory, the type of concepts and the form of experimentation, traditionally acquired in educational laboratories, are fundamental and demand new and better tools. The teaching of electric circuit analysis requires students to compare theory and practice of “learning by doing”, using physical or virtual didactic benches. Virtual learning environments (VLE) allow the organization of more controlled courses, combining classroom and distance lessons, the use of only virtual classes, new possibilities of interaction over the internet, and a closer interaction between teachers and students. The goal of this project was to provide a virtual environment where students can learn and experiment electrical concepts in a user-friendly environment. The software used for this project was Autodesk® 3DS Max, VizUp, Wirefusion and Dreamweaver. An experimental model was designed, which provides the necessary simulations as well as a variety of configurations, to be used as part of the learning process. This prototype of a virtual lab, referred to as VEMA (Virtual Electric MAnual), was developed at the Instituto Superior de Engenharia de Coimbra (ISEC/DEE) to teach circuit theory. The aim of this prototype is the development of three-dimensional replicas of real electrical systems, so that the electrical components can be moved virtually, enabling an easy handling and control of lessons and educational activities in a virtual form. The main objective of the prototype is to be a tool for internet-based distance education (e-learning), complementary to the class contents of Circuit Theory I, also used by students and teachers in or outside the classroom.
