This is a website where you can create "notebooks" containing websites that pertain to a subject of study. You can have multiple binders and can make them either public or private. Making them public makes it possible for students (and others) to access the binder and information. If you want to make certain binders available to students, what I do is have them do a search for the specific name I gave the binder, then tell them which username to access (if there are more than one with the same title.) Very good resource for teachers with many different students going in many directions.
