Why can't students see materials in my site?
When materials are imported from another site, they are designated as "hidden" by default (indicated by gray text). That means they are not visible to students and guests, but are still accessible to instructional staff. This change was implemented in Spring 2009 to match the functionality of our old system and to prevent unintentional release of materials to students, about which there were many complaints.
You can make individual or multiple items visible by checking the box(es) next to the item(s) and clicking the Show link at the top of the screen. Showing a folder will also show all the items within the folder, unless an item is individually designated as hidden. Alternatively, you can show an item by going to Actions > Revise Details, selecting the Show option, and clicking the Update button.
