Curious about this.
Normally, I can do it by increasing the overall weight of the column, but usually the course must have a specific number of points allocated to it.
Do you just want to add extra credit points to a weighted column? If so, I've written a blog post about this.
Ha! That's awesome Thank you Eric Silva
This works great as long as you have every column in the weighted total worth 100%. If you don't (and I've had faculty who don't), this will change the value based on the total points of the weighted grade (I'm not sure how this is calculated).
Right you are Will.
What I've found is this:
If you have a course with 4 assignments and 2 exams.
A1 - 20 pts
A2 - 10 pts
A3 - 10 pts
A4 - 25 pts
E1 - 100 pts
E2 - 100 pts
Then the weighted column is as such:
Assignments = 20%, weighted proportionally
Exams = 80%, weighted proportionally or equally does not matter in this scenario.
What you'll get is this:
Total = 65 points / 4 = 16.25
Total = 200 points / 2 = 100
20% of 16.25 = 3.25
80% of 100 = 80
83.25 / Total.
This is how Blackboard figures out the weighted columns, as far as I can tell.
So that said, when calculating extra credit in this scenario, you run into some mathematical errors.
being the beggar, I'm not going to be terribly nitpicky about this, but do you know of a way to make it slightly more accurate?
Or rather, explain how the math works in this calculation?
