The homepages of most courses have a number of rectangular areas called widgets. Typically, there’s an News or Announcements widget, a Content Browser widget, and others. You can add, remove, and rearrange widgets. You can also create your own widgets.
Modify the homepage if you want different widgets or a different layout. Or replace the standard widgets page entirely, if you wish. For example, you can make a course tool, such as Contents, the first thing students see when they enter the course.
