Please excuse me for interjecting with regard to Jon's comment on different
difficulties. I am ignorant of XML but have found the exchange of ideas
stimulating because I am interested in the subject, particularly vis a vis
the data tracking of student individual responses so that these responses
can be imported into a spreadsheet for analysis of, for example, facility
value (whether the questions are too easy/difficult) and discrimination
index (a measure which sorts out the 'good' students from the 'poor'
students.
Am I correct in assuming that these indivdual responses could all be
transferred into a database on the host server? If so, surely the quiz
question could include a code (for level of difficulty) which could be
transferred into the database (for subsequent amendment/updating)?
Thanks for this exchange of ideas.
Carole
