Choice Interaction (QTI)

The choice interaction presents a set of choices to the candidate. The candidate’s task is to select one or more of the choices, up to a maximum of maxChoices. The interaction is always initialized with no choices selected. The choiceInteraction must be bound to a response variable with a baseType of identifier and single or multiple cardinality. The relevant classes are:

Multi-select

	    <mapEntry mapKey="O" mappedValue="1"/>
	    <mapEntry mapKey="Cl" mappedValue="-1"/>
	</mapping>
    </responseDeclaration>
    <outcomeDeclaration identifier="SCORE" cardinality="single" baseType="float"/>
    <itemBody>
	<choiceInteraction responseIdentifier="RESPONSE" shuffle="true" maxChoices="0">
	    <prompt>
Which of the following elements are used to form water?
	    </prompt>
	    <simpleChoice identifier="H" fixed="false">Hydrogen</simpleChoice>
	    <simpleChoice identifier="He" fixed="false">Helium</simpleChoice>

	</choiceInteraction>
    </itemBody>
    <responseProcessing template="http://www.imsglobal.org/question/qti_v2p2/rptemplates/map_response"/>
</assessmentItem>

Note the mapping here, which sets lower and upper bounds for the score, each wrong entry gives -2, except chlorine, the partial responses of hydrogen and oxygen are awarded one mark each.

Multiple Correct answer sets

Finally, a multiple choice with multiple select answers:
