This is probably because you have set Maximum grade to 2. Try setting this to 6 or something like that, and report back if you still have a problem. Below is a picture of my favorite settings. I don't use "Count" but instead, use Sum. I typically require 4 posts, but by using Sum, I can give a student a 0 or a 1 if their post is too brief, off topic, or of lower quality. Also, I like to set the Restrict Ratings "To" date to 5 minutes after the due date for the discussions. Then I cannot "rate" posts after this date, which is a great indication that the student posted too late.
How to grade in Forum?
As shown in the figure, I can only score 0, 1, or 2 points. Why can't I score any points I want, such as 1.5 points? Where did the settings go wrong? We use Boost theme and Adaptive theme. The issue happens in both themes. What can I do to solve this issue?
