Well I am a (lurking!) mathematician, and I know that one of my colleagues
has used all sorts of cunning tricks (mainly using a computer algebra
package to generate QML, which is Questionmark's version of XML I guess).
This means we can use the test as an exam, in the knowledge that two
adjacent students will be facing different questions. We can also allow
students to practice on the same questions, and even spy on them
electronically to see who has attempted them.
You are probably right in thinking that, with present technology, maths is
the only are that could take advantage of this sort of randomisation; and it
is not at all easy to do, as a certain amount of programming is involved.
I might also mention the DIAGNOSYS package written by John Appleby at
Newcastle, which decides which question to set based on whether the student
got the last one right or not. We have used it to estimate the mathematical
knowledge of incoming students. In our own research here we are interested
in "intelligent" selection of questions in a tutorial setting, but I can't
claim we have got very far with this yet,
