Erik Wilde: Open and Accessible Presentations

(2) Abstract

E-learning often is perceived as something that, on the technical level, can be addressed by designing an e-learning system, which often is equipped with a Web-based interface. We argue that this traditional approach of e-learning system design should be reversed in today's Web-oriented environment, in the sense that e-learning applications should be designed as well-behaving Web citizens and expose their services through nothing else but the Web's loose coupling principles. This article presents a system for Web-based presentations which follows this approach in publishing presentation material in a way that is as Web-friendly as possible. We show how such a system can be used as one building block in an e-learning infrastructure; replacing the traditional view of monolithic e-learning systems with an open and loosely coupled ecosystem of cooperating e-learning Web applications.

(9) How to Build an E-Learning System

  1. Don't!
  2. Design a Web space for exposing content
  3. Build validation and recommendation systems for content publishers
  4. Build crawling, aggregation, and search on top of that space
  5. Optionally, build authoring tools for creating and publishing content
