Gradebooks are complicated
We had a long meeting about what happens to unscored fields when an assignment is released. It effects what the student sees, how the final grade is calculated, how the average scroe is displayed, etc. I changed 6 wireframes in the gradebook specs after the conversation.
I always wondered why most course management systems either lacked a grade book or had one that was airly lame. Now i know that it's because they are really complicated. There are so many different styles of grading to account for. Even when you stick to one style, there are lot's of logical implications to changing the way any one number is calculated.
It's going to take two or three releases to get back to the full functionality we'd hoped for. Right now I'm glad to be implementing one fairly simple grading style, and using this first try to work through all of the weird kinks of logic.
