Information Systems’ Information Systems’ ApproachApproach
A Telelearning system is an information system, a complex array of software tools, digitized documents and communication services, more diversified than in the past
Artisanal construction of web based materials is insufficient, so is the use of simplistic authoring tools
Software engineering approaches can and must be applied to the design of telelearning systems
The actual emphasis on knowledge management recognizes the importance of knowledge and higher order skills, as opposed to simple data or information acquisition
Knowledge engineering needs to be centrals tasks of ISD methods
The product is knowledge elicitation, as well as knowledge based design of telelearning environments
Multi-Agent viewMulti-Agent viewMulti-agent systems is a good way to see a telelearning system at delivery time: actors, agents and their instanciation, message propagation, modularity, sociability, distribution of control
An ISD method should integrate actors definitions and interactions into its mos important tasks
This result in the design of telelearning environments adapted to the functions and roles of the different actors and agents assuming some of these roles
Process-Based ScenariosProcess-Based ScenariosProcess-based learning scenarios help guide information search (for J-I-T) and the construction of new knowledge
ISD methods should favor scenarios built upon a skill’s generic process and collaboration adapted to the process
ISD methods for telelearning must support self-management (and metacognition) of scenarios
ISD methods should help plan heuristic assistance based on principles ruling the generic process.
