In the New Grading entry experience, the Gradebook History area of the student view shows the Current Marking Period rather than the previous marking period for which teachers are calculating grades. Teachers would like to see what averages are comprising the grade they have calculated. In order to see this now, teachers must select one of the percentages for the current marking period, which opens the Grade Detail area, and then toggle to the previous marking period. However, this view goes away once the window is closed.
