Hi @JanetAdeyemi ...
I'm a bit confused about the subject line and how it relates to your question about the Canvas LMS (Learning Management System). By chance, is that the name of a course you are taking/teaching at your school? For starters, are you a student or an instructor? There's too much information to provide about how to use Canvas in a single posting like this, and so if you are a student, I would direct you to the following set of video tutorials:
Getting Started with Canvas as a Student [Videos] - Instructure Community - 256768 (canvaslms.com)
If you are an instructor, however, there is a different set of videos that you can watch:
Set Up Your Canvas Course in 30 minutes or Less - Instructure Community - 258437 (canvaslms.com)
If you are asking about how to access recorded lectures, this would be a question that you'd need to contact your instructor about. Canvas Community members do not have access to your school's Canvas environment or any course(s) that you are taking. Your instructor should be able to tell you the best way to access those lectures. You can contact your instructor directly in Canvas by following the steps in this Guide:
How do I get help with Canvas as a student?
I hope I've interpreted your question correctly, Janet. Please let Community members know if there is anything else related to this topic that we can assist with...thanks!
