arithmetic average instead of %

Asked by xris_xcess

Hi,

Could it be posible to have an option to display the average as the simple arithmetic average of the "grades" instead of the % average (sum of grades divided by total grades)???

At our school we use a rather awkward point system (0.0 to 7.0) and it's not posible to really create a set grading scale for this. I've heard of other people trying to adapt the grading scales but were not successfull.

Any pointers would be great.

Thanks.

Why can't you use a grading scale for this?

Hi,

Well i tried, but its extremly tedious. Basically i would have to asign every decimal point (7, 6.9, 6.8, 6.7... Etc) a % equivalent, only for schooltool to convert to % and then match that BACK to decimal our decimal point scale. No? Am i missing something?
Would it be too much of a hastle to bypass the scale conversion and just do a direct average since i would be setting all of our evaluations to grade from 0 to 7?

Well... I tried to create a scale and I couldn't get it to work.

As I say, if I create a scale, SC will be calculating the % based on the max scores for each evaluation and then the total % and then match that to the scale...

I have tried looking into the gradebook code, but haven't identified the calculating funtion.

I was thinking that there could be another menu item in the average column of the gradebook that just does the simple average, and as I mentioned before (or there could be a simple check) all the evaluations (tests, exams, etc) have to carry the same max and min scores.
