"Student Chapter Access" shows how many chapters a student has accessed. As the instructor, you know how many chapters have been assigned by a given point. Therefore, this is a quick at-a-glance view of who is keeping up with the reading.
The information is presented with the most accessed to least accessed. It lists the student's name and the type of digital product they have purchased. (AAP = Digital All Access Pass; SP = Study Pass
Ultimately, you have access to information and observations that are not captured here. This data is intended to complement or validate that information. Maybe it can help you pinpoint the reasons why a student is falling behind.
It's important to note that, currently, we can only track usage of the online book. Therefore, students who purchase a Digital AAP or print book may be reading offline at times. So, their engagement metrics may not be 100% accurate. However, Study Pass students can only read online, so you are getting closer to 100% transparency with Study Pass users (unless they purchase the color print book which gives them access to the online book, but only a tiny percentage of students do that).
