1) When users access a unit's Content tool for the first time, the first page they land on is the Overview. Use the Overview page to orient users to the unit, content materials, the unit's study guide, and unit expectations. If you decide not to add anything to this page, the Overview link and page is hidden from learners' view. Users can print and download an uploaded unit study guide directly from the Content Overview page.
2) Topics you bookmark appear in a list on the Bookmarks page. The number beside the Bookmarks link indicates how many bookmarks you have.
3) The Unit Schedule page lists unit material due dates, start dates, end dates, overdue unit activities, and other unit events for the next seven days. If you set availability dates or a due date for a unit object, it appears in the Unit Schedule page and the Agenda view in the Calendar tool. If you set a due date for a unit activity that has no end date or it has an end date that occurs after the due date, the activity appears on the Overdue tab for learners who miss the due date. The Overdue tab lists overdue unit activities that learners can still complete before the item or unit becomes unavailable.
The dates listed on this page are not exclusive to content topics; upcoming events include all events within the unit from the Calendar tool. The number beside the Upcoming Events link indicates how many upcoming events you have.
4) The Table of Contents panel lists all modules available in your unit. The number beside each module name in the Table of Contents panel indicates the number of topics you have set completion tracking for. The number beside the Table of Contents link indicates the total number of topics you have set completion tracking for. Use the number totals to determine the task load being put on learners per module.
5) The unit content administration options located on the Table of Contents page allow instructors to import and copy unit content, bulk Unit Admin content properties, manage unit files, view reports on unit content, and restore deleted unit items.
