AUTOMATED GENERATION OF QUESTIONS FOR BASIC ELECTRICAL ENGINEERING EDUCATION

摘要

This paper deals with the problem of automated generation of questions for basic electrical engineering education in e-learning systems. One of the main challenges in developing e-learning systems is to create an effective knowledge testing module. In most of e-learning systems teachers need to manually compose test questions, prepare the correct and wrong answers, and added feedback information. The process is time-consuming and prone to errors. We have focused on problems in basic electrical engineering education, specifically series - parallel DC circuits, and we propose a solution for automated generation of template based questions of various degrees of similarity and complexity. Our prototype Web application dynamically generates text of the question and its circuit diagram image, solves the problem, and as a feedback provides correct results and a step-by-step solution. The interface is bilingual, available in Croatian and English. We have used standard Web technologies, such as JavaScript, jQuery and SVG, together with MathJax for mathematical notation. We will recommend our students on the course Fundamentals of Electrical Engineering to use this Web Application for self-assessment and practice. In future work we plan to advance our Web application and to fully integrate it into our developing e-learning system.
