Prospects of Implementing E-Learning Systems based on Learning Objects and XML in Nigeria's Educational Sector

摘要

This paper started with highlighting the forms of e-learning and pointing out the key difference between Synchronous and Asynchronous e-learning. It described the popular e-learning systems that gained ground and recognition in Higher Institutions in countries like Nigeria, and went on to point out the need for resident application developers and computer interaction designers to study the existing conventional e- learning systems out there with the aim of finding possible ways to extend/improve the interactivity, accessibility and compatibility of suchdisparate systems through the use of XML(Extensible Markup Language) and learning objects such as Avatars and Embodied Conversational Agents (ECAs).
