I have created a course for my PLC; however, what role can I assign for the teachers I add that allows them to export material but not change any parts of the PLC course?
Welcome to the Canvas Community. Without being able to see the roles in your instance of Canvas I can't say for sure. None of the built in roles have exactly those permissions but an Admin on your system could modify the existing permissions or create a new role that does what you are looking for. For instance, at my school we have a role named "Copier" which does pretty much what you are asking for. People in this role can see and export content from the course but they can't create, edit or delete content, AND they can't access any student data for privacy reasons. Below is a screenshot of the permissions we have assigned to this role. An admin on your system would have to set up such a role for you.
Hope that helps,
