Finally, the glossary!
When setting up your the Organizer page remember the "keep it simple rule". You don't want an overwhelming number of options but neither do you want students to have to drill down several times to get to the tools they need.
In this example, it takes the students three clicks to reach the glossary when it would have been fine to add the glossary on the first page.
Try to keep the number of "clicks" needed to a minimum.
