I agree! The pages format makes manually assigning Peer Review VERY arduous labor. While the old format is a long page long, and modern consumers of information do not like long pages, this is a different circumstance and context. The instructor is trying to manage the entire course NOT consume information in chunks. PLEASE ask Canvas to change it back or build in the option for the instructor to toggle to their preferred interface: pages or scrolling list. This is important and affects the labor that teachers must expend doing what should be a simple task. It is important to the function of the interface; it isn't just preferences in question here. The Pages have decreased the accessibility of the interface and complicated ease of navigation for instructors.
If you are listening Canvas (or Canvas's AI)--Please elevate this conversation and take a look at this important issue.
