Prototype implementation by Jennifer Grant and Mark Hakkinen - Educational Testing Service
This is an initial prototype implementation of a QTI choiceInteraction [1] implemented using the W3C Web Components Technology [2]. It is feature incomplete and not meant to represent a definitive approach to using Web Components for representing QTI elements in HTML.
The implementation uses Google's Polymer Library to implement the component [3].
aqtidemo.html is your starting point. It contains both the polymer definition of the qti-choiceInteraction, as well as the usage of the component in HTML. Use chrome, as we have found polymers' cross platform behavior problematic.
You can try out a working demo here [4].
