@TerishaSigler ...
Good morning. Each school that uses Canvas as their LMS (Learning Management System) usually has a slightly different process to sign in to Canvas compared to another school. So, you may need to reach out directly to folks at your school such as your Online Learning / eLearning / Distance Education department or a Canvas administrator. I navigated Houston Community College's website, and I found a few support pages that have some helpful information for you:
Once you have logged in to Canvas (I think they call it "Eagle Online" at your school), then you can contact your instructor within Canvas. (This assumes that you can see the courses you are taking. If you can't find your courses in Canvas, then you'll need to use one of the above links to get help at your school.) To contact your instructor in Canvas, you can use this Guide:
How do I get help with Canvas as a student?
Hopefully these links will be of use! Let Community members know if you have any other questions about this...good luck!
