How to make a multiple choice or short answer question that requires more than one correct response

How to make a multiple choice or short answer question that requires more than one correct response

Hi


I need to set up multiple choice and short answer questions that require more than one response for more than one mark.

For example.

1. In a short answer questions, I want to ask for two names: "Name the two main characters in the novel for two marks."

And in grading I need to be able to assign 1 mark to each response, thus allowing students to score 1 or 2 out of 2. Right now I can also seem to ask for one response. I can list multiple correct responses in setup but students can only enter one response to be marked. 


2. In the multiple choice questions, I want to ask students to choose more than one option, each for a mark. For instance: "Choose 3 of the words below to describe the tone of the novel".

Thus students must be able to score 1, 2 or 3 out of 3 depending on their answers. I have been able to select "multiple answers" here but find that students then only get 1 mark if they get all the answers correct. So its a 1 or 0, all or nothing grade.

Hi Adri,

Please remember the usual forum rule: one question per post only!

Answer to your question #1

In the Lesson settings -> Grade -> Show more -> Custom scoring: Yes

Question #1

Page contents: Name one main character for 1 mark or two main characters in the novel for 2 marks.
       Use regular expressions

Answer 1 Brian -> Jump Next page -> Score 1
Answer 2 Mary -> Jump Next page -> Score 1
Answer 3 Brian (and|&) Mary|Mary (and|&) Brian -> Jump Next page ->Score 2

The regular expression in Answer 3 will accept as correct answers:

  • Brian and Mary
  • Brian & Mary
  • Mary and Brian
  • Mary & Brian

Answer to your question #2

Unfortunately the scoring system of the MULTICHOICE question in the Lesson activity is buggy and does not work as one would expect. This bug has been reported quite a few times and will probably never be fixed. 伤心

Thank you for your reply. And apologies for breaking the one question rule. In my head it was two scenarios of the same scoring issue.


I have tried your advice on the short question answers. However, I get mixed results with some combinations of the names scoring 2 and other combinations only scoring one. I am wondering if it is the location of spaces in the formula or even that I am trying too many variables?

I attach screenshots of my entries. As you will see, one of the two characters also has a nickname so I needed to allow for that as well. 

So answer 1 was

Ruan  > score 1

Answer 2

Cissie| Cecelia  > score 1

In a testrun, all 3 of these answers score 1 mark successfully.

However the longer "formulas" are giving me trouble. I entered as follows:

Answer 3 

Ruan (and|&) Cecelia| Cecelia (and|&) Ruan

In a testrun, the 2nd combination of names scores 2 succesfully, while the first combination scores only 1, strangely enough.

Answer 4

Ruan (and|&) Cissie| Cissie (and|&) Ruan

Conversely, in a testrun,  the first combination of names scores 2 successfully while the 2nd combination, only scores 1. 

This makes no sense to me. I have tried with no spaces and spaces between entries. I have tried one long formula:

Ruan (and|&) Cecelia| Cecelia (and|&) Ruan| Ruan (and|&) Cissie| Cissie (and|&) Ruan

and interestingly, the same two answers score 2 marks and the same two scores only 1 mark, just as when I break them up into the two shorter formulas  as shown above. I find no logic in this.

What am I doing wrong?

@Adri,

Of course spaces are important in regular expressions!

Your expression Ruan (and|&) Cecelia| Cecelia (and|&) Ruan| Ruan (and|&) Cissie| Cissie (and|&) Ruan

should be re-written as

Ruan (and|&) Cecelia|Cecelia (and|&) Ruan|Ruan (and|&) Cissie|Cissie (and|&) Ruan

i.e. No spaces before or after the pipe character |

It could be shortened to:

Ruan (and|&) (Cissie|Cecelia)|(Cissie|Cecelia) (and|&) Ruan

If you want to adopt the Regular expressions in your Lesson short answers I suggest you read the documentation I wrote at Short_answer_analysis

Thanks Joseph

I actually inserted the spaces in one of my many attempts to make it work as a beginner.

NOW I copied and pasted your formula and it was still only giving full marks to two of the four possible combinations of names. (The same two as previously)

However, after I deleted the expression in Answer 2 > Cecelia|Cissie, and just made the two names two seperate answers, it worked.
Possibly the two expressions were "clashing" if such a thing is possible.

Thanks for your help. I will definitely be reading your documents on regular expressions.

Congratulations for persevering!

The following should work as expected:

Answer 1

Ruan (and|&) (Cissie|Cecelia)|(Cissie|Cecelia) (and|&) Ruan

Score: 2

Answer 2

Ruan|Cissie|Cecelia

Score: 1

The order of Answers is important!
