[QTI] RE: Two correct answers for text entry

[Gorissen,Pierre P.J.B.]

Hi Mark,

You could use:

<correctResponse>
        <value>He is called</value>
</correctResponse>
<mapping defaultValue="0">
        <mapEntry mapKey="He is called" mappedValue="1"/>
        <mapEntry mapKey="He's called" mappedValue="1"/>
</mapping>

Or

<correctResponse>
        <value>He's called</value>
</correctResponse>
<mapping defaultValue="0">
        <mapEntry mapKey="He is called" mappedValue="1"/>
        <mapEntry mapKey="He's called" mappedValue="1"/>
</mapping>

The correctResponse element contains "A human readable interpretation of the correct value." (see: http://www.imsglobal.org/question/qtiv2p1pd2/imsqti_infov2p1pd2.html#element10077). In case of multiple equally correct values, you can just choose one and make sure that the response processing takes into account all the possible correct values while scoring.

Onderwerp: [QTI] Two correct answers for text entry

Hi all,

I have a question about text entry questions (QTI v2).

The R2Q2 website (http://r2q2.qtitools.org/r2q2) QTI website has a sample based on the textEntry sample that can be found on the IMS
website:

http://www.imsglobal.org/question/qti_v2p0/examples/items/text_Entry.xml

It defines answers: "York" and "york". "York" (with capital Y) is considered the correct answer and "york" is considered incorrect.
However the user is awarded 0.5 points for "york" (he was pretty close after all).

Now consider the following question where there are two possible
answers:

"He is called"
"He's called"

Both could be considered equally correct, however only one can be defined as THE correct answer in QTI v2.

How should this text entry scenario with two equally correct answers be defined in QTI v2?

Thanks,

Mark Breuker
