We are trialling Canvas at present. Our teaching staff want to set up rubrics in Canvas as we currently use them here, with no scores. Here rubrics give an overall indication of how well an assignment has been answered, but do not necessarily directly translate to marks. They are more of a guide for the students, not really a set of points, and is how UK TurnItIn works.
In Canvas there seems to be no way to do this. So here for example we want to show these levels of attainment on a scale, but not show any kind of point or total (as here).
