Web-Based Technologies for Online eLearning Environments

Abstract: Implementing an e-Learning system is not just about bringing a new technology in practice and improving teaching and learning. It is also about changing long-lasting conceptions that in classical methods are better than in computerized ones, without replacing them. This is also why software solutions for online learning and testing must be as user-friendly as possible, but also provide high-quality solutions to suit the teachers ’ and learners ’ needs. This paper shows our developed e-Learning system, Education Management Tool, with the purpose of enhancing classical teaching and examination methods, without replacing them. EDM is continuously being developed and perfected, with new modules and functionality added regularly for efficient communication and collaborative project work of students or document management of teachers. We also extend the interactive teaching section with lessons focused on graph algorithms (breadth-first search, depth-first search, Dijkstra, etc.) and binary tree operations (insertion, deletion, traversal, search, etc.). Such algorithms can be better explained through visually illustrated examples which might help the students to easier understand them. Therefore, we present the above mentioned algorithms with the help of interactive Flash files as part of the lessons
