Web 2.0 is the term to describe the second generation of applications that facilitate the communication, socialization, and collaboration through the World Wide Web. Web applications that include social networking, video-sharing, wikis, and blogs are being used more and more to deliver instruction in formal environments. Despite the good intentions of faculty members to include Web 2.0 capabilities in their courses, the reality is that often courses are not designed with usability in mind. This session will present a framework to design online courses that integrate Web 2.0 applications using a task oriented methodology. This methodology facilitates the interaction of the learner so that the learner can concentrate on completing learning tasks.

A system is usable when users spend most of the time achieving
their task and the least understanding the system itself

25. CONCLUSIONS AND FUTURE WORK
Learners should spend less time as users and focus more on the
learning tasks
26. A design that does not meet users' needs
will often fail in the workplace resulting in
high costs, frustration, and errors that
affect learners
Any system design should start by listing
the tasks the users need to do with the
system
Visual cues should have a semantic
relationship with the task
27. Future Work:
Development of an online tool that supports
instructional designers during the
design/development/analysis of online
courses
Develop more online courses, gather data
and validate methodology
Develop mechanism to automatically analyze
online courses and generate quantitative
metrics for usability
