If you would like to see how a specific participant is doing in your D2L course (view assignments completed, grades earned, etc.) click the down arrow to the right of the participant's name and select View progress.
Once you are on the Progress Summary screen, you can then use the menu on the left side of the screen to sort by what you'd specifically like to see.
Login History: In addition to the different course tools, View Progress also allows you to view a participant's system login history. This will show you every time a participant logged into D2L. Unfortunately, at this time, system login history does not show you which D2L course sites a student accessed while logged in, only that they were logged in on a particular date and time.
