Use the Classlist to find the last time a student accessed the course
Within the Classlist, you'll find a column titled "Last Accessed." This column shows the last time each student accessed your course (not just D2L in general). You can also click the Last Accessed header to sort the Classlist by the time and date when each student last checked the course. This can be very helpful at the start of the term for identifying and reaching out to students who haven't yet accessed the course. You should also consider checking student login statistics periodically throughout the term to identify students who might be falling behind.
