Via the zyBook’s class management page, an instructor can set up a zyBook to have class sections. Students are then required to choose a class section when subscribing, and can change their own section as well.
Class sections support the common class model where a few instructors (including TAs) co-teach a single large class. Due to a school’s room size constraints or to provide student scheduling flexibility, students at a school may enroll in different sections of that large class. The zyBook’s section attribute is thus a convenience that allows instructors of such classes to download activity reports for specific class sections.
In that common class model, the students are still part of one large class, and the instructors are all teachers of that one class. As such, instructors (including TAs) can see all students, can run reports on any section, etc.
Specifically not supported is restricting instructor access to only specific sections, allowing instructor notes to appear only in specific sections, allowing configurations to differ across sections, etc. Supporting such features introduces numerous complexities, both to the user model, and the implementation, and is not a kind of class section model that our section feature is designed to support. If your class has multiple sections that differ from the above common model and instead are more independent, you may wish to create multiple class zyBooks.
