It would be good if:
1. When one assign the material, the system somehow track it. That way we do not miss assigning material.
2. When looking at the material assigned, one could look per subject and could tell estimated amount of minutes for completion.
3. Maybe there could be a template that enable assignment per week (sample assignment for people to follow)
4. It would be good if teachers could create their own content and assign them. Maybe that helps Khan Academy to have more content available faster (if the teachers agree to share it with the site.
