Since the public beta of edu 2.0, we've been working on improving the user experience as well as adding various new features. For fun, we're keeping a daily journal of our progress.
Much of the time has been devoted to adding features like forums, email integration, RSS integration, 3rd party news feeds, and various social networking functions. They're all important features to have on an education site, but not particularly enjoyable to implement.
The rest of the time has been spent on adding more interesting features like support for project-based learning, webquests, and other types of educational material.
We hope to add the remaining must-have features like calendar support and user page creation in a couple of weeks, at which point we'll start marketing the site. We're revamping our home page next week to better communicate what the site does, based on early user feedback.
I'm most looking forward to working on the cool education ideas that I've been gestating for the last few years, but this first phase is essentially the price of entry to get to that point.
Once the final must-have pieces of edu 2.0 are in place, I'm planning on using the software to teach a computer science course on the Internet; I used to be a professional computer instructor and would love to share some of my lessons learned. I also have no doubt that using the system for delivering my own materials will yield a ton of ideas for improvement.
