Graphic Order (QTI)

A graphic order interaction is a graphic interaction with a corresponding set of choices that are defined as areas of the graphic image. The candidate’s task is to impose an ordering on the areas (hotspots). The order hotspot interaction should only be used when the spacial relationship of the choices with respect to each other (as represented by the graphic image) is important to the needs of the item. Otherwise, orderInteraction should be used instead with separate material for each option. The delivery engine must clearly indicate all defined area(s) of the image. The order hotspot interaction must be bound to a response variable with a baseType of identifier and ordered cardinality.The relevant classes are:

GraphicOrderInteraction

	<p>
Lorna is flying back home to the UK. Ideally, she would like to fly in directly to her home town of Glasgow. Edinburgh is her second choice and, if necessary, she could fly into London and pick up an internal connecting flight. Although she has been offered a cheap flight to Manchester it remains her least favourite option as connecting flights to Glasgow are not very reliable from there.
