As a Student, you can edit Course Pages and Group Pages.
The default setting in Curve is to restrict editing of Course Pages to Instructors only. However, Instructors can allow students to edit pages. If you can edit a page in your course, your instructor has allowed you to contribute content to the page.
When you can edit a page, you can also view the history of a course page.
In Course Navigation, click the Pages link.
Click the title of the page.
Click the Edit button.
Note: You will only see the Edit button if you are allowed to edit the page.
Edit content on the page using the Rich Content Editor.
You can notify users that content has changed by selecting the Notify users that this content has changed checkbox . Click the Save button  to save your edits.
