Your professor will sometimes put some text, images, videos, or links in this spot that introduce you to the topic for the week or unit.
The lower part of the screen after the Module Description will usually contain links to various course media, such as articles, video, documents, websites, etc. You may also find links to any assignments, discussions, quizzes or exams your professor has assigned for that week or unit.
Your professor can make links active and inactive, so if you come across a module with a list of black links that don’t respond to clicking or tapping, it likely means your professor has not enabled access to them yet. If you think something is inactive that shouldn't be, don't hesitate to reach out to your professor!
