[QTI] IMS QTI V2.1 PD (revision 2)

[Yvonne Winkelmann]

Hello,

our corporation develops a test modul for established learning management systems like OLAT adapted from IMS QTI version 2.1 public draft. Revision 2 which contains a couple of extensions and changes (e.g. result reporting) was published in June. My first question is whether you know when final specification v2.1 will be available because I did not find any information at http://www.imsglobal.org/workinprogress.html.

Furthermore I have some questions to the IMS QTI 2.1 public draft (revision 2).

The first one concerns the duration type. 

<xsd:simpleType name="duration.Type">
	<xsd:restriction base="xsd:double"/>
</xsd:simpleType> [new -(IMS QTI V2.1 PD (revision 2)]

It was changed from restriction base "duration" to restriction base "double" but we could not figure out which time unit the double value has. I suppose seconds but it should be described in the specification. Where can I find this?

My second question concerns the result reporting.
Unfortunately I only found one report file in the examples which was not in relation to a content package. Now the itemSession status element and the attributes were replaced by the itemVariables "numAttempts", "duration" and "completionStatus".

<itemSession numAttempts="1" duration="35" sessionStatus="final" completionStatus="unknown"> [old - (IMS QTI V2.1 PD)]

Where is defined which of this variables for which items or tests are shown in the report file? 
The example looks like this.

    <testResult identifier="SAMPLE" datestamp="2005-12-02T15:19:20">
        <responseVariable identifier="duration" ...>
            <candidateResponse>
                <value>300</value>
            </candidateResponse>
        </responseVariable>
        <responseVariable identifier="S01.duration" ...>
            <candidateResponse>
                <value>10</value>
            </candidateResponse>
        </responseVariable>
	...
    </testResult> [new -(IMS QTI V2.1 PD (revision 2)]

There is only the itemVariable "duration" but this one for the whole test and for the section S01. I do not know if there are more sections but there also is a testPart. My question is: How does the tool know which itemVariable should be shown in the result? This question will be even more important if you additionally consider the items of the result example.

<itemResult identifier="Q01" ...>
        <responseVariable identifier="numAttempts" ...>
            <candidateResponse>
                <value>1</value>
            </candidateResponse>
        </responseVariable>
        <responseVariable identifier="RESPONSE" ...>
            ...
        </responseVariable>
        <outcomeVariable identifier="completionStatus" ...>
            <value>unknown</value>
        </outcomeVariable>
        <outcomeVariable identifier="SCORE" ...>
            ...
        </outcomeVariable>
    </itemResult> [new -(IMS QTI V2.1 PD (revision 2)]

"CompletionStatus" is an outcomeVariable and "numAttempts" is a responseVariable. The itemVariable "duration" is not shown.
I do not understand this improvement. Now the responseVariables and outcomeVariables "numAttempts", "duration" and "completionStatus" are jumbled with the learnerResponses and outcomeVariables which are defined in the items or tests.

Thanks in advance for responses
Yvonne
