hi all,
i have two question formats:
1.listening singlechoice
student listening to a recording ,then answer the question.
the recording must have those attributes (src\mimetype\duration\comments\repeatTime\repeatInterval)

i known how to represent a normal singlechoice question but don't
known how to represent the recording on QTI V2.1?

2.oral question
student reads the question then prepare for several seconds and then the software records the content that the student speaked ,at last the software uploads the recording file as the response for the question.
how to represent this kind of question on QTI V2.1?

Hello,

For question 1, I'm not sure how you've made your single choice questions, but I think I would embed the audio recording in a QTI 2.1 item via the HTML 'object' tag in the prompt. The choice interaction can then follow the pattern of any single or multiple choice question item- the examples that come with the specification could provide some useful code and inspiration: http://www.imsglobal.org/question/index.html

Question 2 is trickier; you could use the 'file' interactiontype, but that won't capture how the recording interface is meant to look or work. I suspect that an 'audio' custom interaction type is a better solution. BPS Systeme's Onyx has defined exactly such an custom interaction type, but I'm not sure how it works or what it looks like http://www.bps-system.de/cms/index.php?id=43&L=1

Hello,

for point 1, there are two possible solutions:

A: Use of the HTML object element
B: Use of QTI mediaInteraction

<itemBody>
<p>Listen to the recording:</p>
<mediaInteraction autostart="false" responseIdentifier="RESPONSE_MEDIA">
<object data="media/cadf9495f10e4518a970f71fd48d5022.mp3" type="audio/mp3" />
</mediaInteraction>
<!-- OR -->
<p>
<object data="media/cadf9495f10e4518a970f71fd48d5022.mp3" type="audio/mp3" />
</p>
<choiceInteraction responseIdentifier="RESPONSE_CHOICE" shuffle="false" maxChoices="0">
<simpleChoice identifier="choice_1">true</simpleChoice>
<simpleChoice identifier="choice_2">false</simpleChoice>
</choiceInteraction>
</itemBody>

For point 2, you need a custom interaction.
Based on our customers needs we have defined two different ways for the Onyx Testsuite of BPS GmbH.

A: The recording is synchronized to the audio output (ci_record_01.AttrGroup).
B: After an audio output follows an audio recording (ci_record_02.AttrGroup). In addition, a think time are defined before the audio recording will start and a warning time (with appropriate warning sign) before the recording ends.
