We integrate our SIS (PowerSchool) with Schoology rostering. Our sync is scheduled overnight, so that as students change their schedules (which is frequent in the beginning of each semester), the Schoology rosters are changed the next day.
Many schedule changes result in students moving between teachers (not necessarily sections, which could be linked). After the sync, students are dropped and teachers don't have a method of seeing who was lost. In our PowerTeacher Gradebook, we can sort students by Active or Inactive (which is for dropped students), which helps us communicate what a student's grade was to the next teacher or helps us go back and see what they did. We'd like to see a similar function in the Schoology Members page. First, we'd like to be able to sort students by Unenrolled and see who they were. Then, we'd like to be able to view their prior submissions or grades in some way.
