Web-Based Learning Environment Architecture (WLEA)

The E-Learning systems represent a new philosophy in educational organizations. The main features of the E-Learning are the interactions between the instructor and the learners via the electronic instruments, and the personalization of learning material according to learner preferences. This paper introduces a Web-based Learning Environment Architecture (WLEA) which aims to define the different layers for a platform independent framework to support material interoperability, software reusability, and system scalability. It includes authoring tools for course, lesson, learning object, different media types. It includes also, synchronous services (chat, online discussions), and asynchronous communications (discussion forums, messages, queries….). The Architecture allows the existence of different user levels according to their roles and supports different educational scenarios for virtual classroom, as well as collaborative learning.
