Gap Match Interaction (QTI)
A gap match interaction is a blockInteraction that contains a number gaps that the candidate can fill from an associated set of choices.
The candidate must be able to review the content with the gaps filled in context, as indicated by their choices.
The gapMatchInteraction must be bound to a response variable with base-type directedPair and either single or multiple cardinality, depending on the number of gaps. The choices represent the source of the pairing and gaps the targets.
Each gap can have at most one choice associated with it.
The maximum occurrence of the choices is controlled by the matchMax attribute of gapChoice.
The relevant classes are:
Data Models
GapMatchInteraction
Gap
This defines the gap structure that must only appear within a ‘gapMatchInteraction’.
GapChoice
This is an abstract representation for the selection of either a GapText or a GapImg object.

This interaction is similar to matchInteraction except that the choices in the second set are gaps in a given passage of text and the task involves selecting choices from the first set and using them to fill the gaps.
The same attributes are involved in controlling which, and how many, pairings are allowed though there is no matchMax for the gaps because they can only ever have one associated choice. The scoring is again done with a mapping.
Additional formatting may be applied within the gapText element allowing for a greater variation.’ Allowed formats include: ‘br’, ‘img’, ‘include’, ‘math’, ‘object’, ‘printedVariable’, ‘a’, ‘abbr’, ‘acronym’, ‘b’, ‘big’, ‘cite’, ‘code’, ‘dfn’, ‘em’, ‘feedbackInline’, ‘i’, ‘kbd’, ‘q’, ‘samp’, ‘small’, ‘span’, ‘strong’, ‘sub’, ‘sup’, ‘tt’, ‘var’, ‘templateInline’.
