If you asked for a password reset and nothing arrived, first check that you are signing in to the right place. How you sign in depends on how you got your course materials. This article covers:
If your materials are in Canvas or Blackboard
If you signed up in the Blended Library
The instructor sign-in won't work for students
1. If your materials are in Canvas or Blackboard
If your instructor set up your Blended Teaching materials inside your course in Canvas or Blackboard, you open them from your course there. Everything you need is in your course.
Sign in to Canvas or Blackboard as usual and open any Blended material in your course.
2. If you signed up in the Blended Library
If you created an account to get your materials, you sign in at the Blended Library. Once you're signed in, your courses are listed under My Learning Materials, at the top of the page.
This is the account to reset if you have forgotten your password. For how to do that, and what to do if the email doesn't arrive, see How can I reset my password?
3. The instructor sign-in won't work for students
The sign-in on blended-teaching.com is for instructors only. It is a different system that holds no student accounts, so you can't sign in there as a student. If you ask it for a password reset, no email is sent, because there is no student account for it to reset.
