A web-based virtual laboratory workbench for electrical circuits with a watch-dog monitor

Abstract

Laboratory teaching and learning is posing a number of challenges in resources constrained engineering faculties because of the cost, time and space requirements of the traditional engineering laboratory. Although, some research work and development on virtual laboratory alternatives have taken place, more efforts are required because of the diverse training needs and requirements of electrical/electronic engineering curriculum. In this paper, the development and implementation of a Web-based Virtual Laboratory Workbench is presented. A distinguishing feature of this Virtual Laboratory Workbench is that it allows the instructor flexibility in designing laboratory exercises so as to integrate specific knowledge objectives, outcome concepts and pre-requisites with the activity instructions. Another important benefit is that it has a watch-dog monitor that keeps a log of the students’ activities that will help the teacher in assessing and monitoring of students’ work. This can be very useful for large classes. Furthermore, it is web-based and developed using open-source ware, consequently it can open a new door of opportunities because the same concept can be used to develop many more electrical and electronic engineering laboratories.
