Consequence

• Proliferation of developments

[Abrams et al.,2001]


Technical Aspects

•The LMSs impose a series of challenges in different areas:

•Software engineering aspects– It takes time to develop a user interface with a new device, a

new interaction technique– It takes more time to develop a toolkit– It takes even more time to rely on a model-driven approach

•Usability engineering aspects– New user interfaces are shipped with usability problems because

• Little or no experience• No past, no empirical evidence

– Empirical experiments require a lot of resource if done carefully


The proposal: ECOOL

• ECOOL: supporting the dEsign of COllaborative Objects for Learning

• ECOOL is a LMS architecture conceived to support the design of learning content on a collaborative context.

ECOOL relies on the existing characteristics of a VLE system, Claroline which are:

Users’ manager. Courses’ manager, Search for courses, Visualize the content of a course, What’s new section,Agenda, Announcements, Documents and links. Exercises. Learning path Assignments, Forums, Groups and Chat.

Plastic User interface

• Property of plasticity = adaptation to the context of use while satisfying predefined usability properties of interest

Conclusion

In this paper we have presented:1. An alternative method for the automatic generation of

Collaborative Multiplatform Scenarios with Interactive Learning Objects. Note:This implies: a change in the current paradigm from eLearning to mLearning (Mobile Learning) to mpLearning (Multiplatform learning)

2. The overall learning process is seen as a workflow.

3. This approach introduces a flow control that allows tackling at the same time, the problem of divergence in individual learning and the definition of the learning process in terms of collaboration agents and processes.

4. The introduction of a meta-description (in UsiXML) that is going to aid in the process of generation of multiple Uis.
