This is most likely an IU Online Class Connect course. Find more information about this kind of course by visiting About IU Online Course Connect or contacting the IU East Center for Faculty Development.
Courses will automatically populate to the students Dashboard.This is also where you can set a course 'nickname' for your own use. Be cautious about changing the name of a course in the course Settings tool - a change there will affect all users and could cause students to not recognize your course. Note: Students will not be able to access course sites or materials in Canvas until the are published (by default, all Canvas sites are unpublished until the instructor chooses to allow access).
Most students now have some experence with the Canvas LMS, however, you might have a new student, or someone who has not taken online courses before. Please feel free to refer them to the Canvas Student Help Guides and videos (and to link to the guides in your course!). Students can find technology help at the IT Help Desk 24/7.
