Description

A 'container' which allows for a random question to be selected at run-time.

Rationale

In formative self-assessments it is useful in some situations to randomise which questions are presented to students each time they go in.

Notes:

This question is randomising within pre-defined question blocks. It is not randomising the presentation of questions on a paper.
They should not be used on summative exams.
Calculation questions are not supported in random question blocks (They will be from 6.0.3)

At run-time a question is selected at random from the pre-defined block of questions.
It is possible to use the same random question block ID multiple times on the same screen.
- The system knows which 'child' questions have been previously picked and will seek to choose another unique question at random for identical random questions further down the page.
When a question is selected by the system all the standard 'rules' of this question type then apply.
Once a random question has been selected at runtime for a particular question is must not change when going between screens.
