Questions corrected by the instructor

Added by Björn Johansson almost 10 years ago

Hi, I have recently started using AMC and it works quite well for me. What I like most is that it is flexible and forgiving since you can change most things (even correct errors in questions) after the exam have been given.

I have a few questions though:

I usually add one or two open ended questions like this one (AMC-TXT format)

**<lines=8> Explain the mechanism of the Bacillus thuringiensis CRY toxin. 
+[0]{0} 0
+[1]{1} 1
+[2]{2} 2
+[3]{3} 3
+[4]{4} 4
+[5]{5} 5

What I would like here is for me (the instructor) to grade an open ended question.
Usually i do this in the "data capture" tab>

I found that for the question above I have to fill all the boxes to give a full grade.
To give the grade four, I have to fill 0,1,2,3.

I would like it to be enough to fill out only one of the boxes for a grade.

Is there a way to do this? I am sorry if this is in the docs somewhere, I have looked but either did not
find or understand it.

Sincerely,
Björn

With this setup, the question is a "multiple" question (use of **): it can have multiple correct answers. The numbers inside {} are ignored for multiple questions scoring strategies, so each correct answer get 1 point. Moreover, all answers are declared correct (with the + sign). So one can get at most 5 points. If you fill 4 boxes (any of them), you will get 4 points out of 5.

If you need to select the number of points checking one box only, prefer this setup:

*<lines=8> Explain the mechanism of the Bacillus thuringiensis CRY toxin. 
-[0]{0} 0
-[1]{1} 1
-[2]{2} 2
-[3]{3} 3
-[4]{4} 4
+[5]{5} 5

(checking two boxes gives an "error", so no points at all)
