--- Server: Bb Learning System Release 6.3-7.x(??) | Client: Other(WIN) ---

Attached is the Grading Schema I used. The grading schema is set to
compute grades using a 0-50 scale.

Also attached is the grade center display after I'd entered the quiz grades.

Here are the problems:
1) Bb converted all the quiz grades to A+.
2) Bb displayed the scores on a 0-100 scale instead of a 0-50 scale.
3) Bb rounded certain grade schema entries incorrectly such as 49.062 which
should have been 49.063.

I verified these results on both Firefox and IE.

How do I fix this?

Lawrence,

You can't set up schemas on a "0-50 scale". Schemas are based on a percentage correct from 0 to 100, NOT an absolute point value. That allows you to use the same schema for different items that have different point values.

The schema you have set up grades everything from 49.062 correct to 100 correct as an A+, so any student with more than 49 correct is getting an A+.

If you change the values around to operate on a 0-100 scale, your schema should work fine.

(Sorry about the delay in my response -- it took so long for me to browse the forum, I had to give up and try the forum another day.)

I think I was able to fix the grade display problem.

I erased the bad Grade Column. I created a new Grade Column. Then I set Points Possible to 50. The grades displayed correctly.

Thanks for your input.

I came across this discussion and had a similar question. If I'm using a 4.0 grading scale (A = 4.0, A- = 3.7, and so forth), how do you create a grading schema with that approach?  Do I have to convert all of the grade ranges into multples of 100?  I've tried several times using the grade ranges that I normally use, and the system (for whatever reason) doesn't like that approach.

Thank you for any assistance you can provide.  Michael Bitzer

Michael,

It looks like your school is using Blackboard 9.1, not CE/Vista, so you probably should look and post over in the 9.1 Faculty and Designers area (http://discussions.blackboard.com/forums/66.aspx) rather than this one.

But as has been mentioned before, a grading schema is a mapping from a particular percentage range between 0-100% (points awarded / points possible)  to a particular label.  There's no way to translate directly from "A" to "4".  However, you can have both a "Letter" and a "4-point scale" schema, both based on the same percentage ranges, and display either or both (one as primary and one as secondary).

Does that help?
