[QTI] choiceInteractions as rows of a table

[Graham Smith]

Hi Bart:

I agree with my colleagues that interleaving  XHTML tsgs and QTI  
elements is not a good idea. I think the <table> element, common to  
XHTML and QTI, is particularly unfortunate.

You might be interested in my solution to a similar problem, extracted  
from the JAssess QTI demo website.

This is not quite the same as your example, in particular because I  
have used a matchInteraction, but it might give you some ideas. You  
see I have given the student a 'don't know' option. This allows a  
student to show that he knows a suggested answer is false. It also  
gives a place for a default checked radio button (altho JAssess does  
not mark a default radio button).

You will see that I have kept the xml free of much formatting  
information. This helps to improve the interoperabilty of the xml.

I have used a combination of the rendering engine's xhtml output and a  
stylesheet to achieve the effect, leaving others free to adopt their  
own styles.
So for example it is easy to switch between 'buttons to the left of  
the choice' and 'buttons to the right of the choice'.

I attach:
1. An image of the result
2. The QTI XML.
3. The rendering engine's xhtml output of the bit which represents the table.
4. The Stylesheet

That might or might not help:

Regards

Graham
