I used edu20.org as my learning portal last school year. I thought it was wonderful, but I have no perspective whatsoever. I liked the fact that it had so many features for free (I didn't even use most of them). My favorites were:
- Walled Community
- "internal" student email addresses
- Interactive grading rubrics
- Self grading quizzes.
- Student portfolios
As I plan for next school year, I am thinking I should see what else is out there. Are there any other portals I should check out?
