first item in a scale with sum aggregation

Hi all,

I want to rate postings in a forum with a scale like "0 points, 1 point, 2 points, n ponits" and sum up all points of each participant. The first item of the scale "0 points" however, is obviously valued as 1 using sum aggregation with this scale.

Is there a way to define that the first scale item is valued as 0. Thanks for your help.

Best Fritz

Fritz,

You really don't need to create a scale. Use the built in 100 point scale. If you want to make each post worth 5 points, choose 5 from the drop down list. If you want it to be worth 20 points, choose 20. Then you will have the option of rating the forum 0-n.

thanks Rob for your support,

basically you are right and I have already thought about this, however the output of this default scale (1/20, 2/20 etc.) under a rated forum posting has turned out to be very misleading for my students.

I would prefer an output like "0 points, 1 point etc." for each posting without displaying the maximum score of the whole activity.

Do you have any idea to get this? Maybe there is a way to change the display of the default scale.

Thanks for your help,

best Fritz

Hi Praveena, not really, unless you hack the code. You can always enter such decimal numbers in the gradebook directly, but I do understand that it defeats the purpose.
