I find that with online courses students are more introverted and are afraid to share or ask questions. A great way to keep in the know that students are paying attention, and understanding is to post poll questions throughout the class. It is important to make sure that the tasks are well-defined. I often provide a Google Drive folder that is created by myself with extra resources such as templates and breaking down rubrics. While the classes may allow time for them to work independently, making sure they have support and good communication on tasks and due dates is essential.
