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:

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

Fit Criterion

Presentation

• 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.

Marking

• Marking should follow the 'rules' of the selected 'child' question.

Feedback

• Feedback should follow the 'rules' of the selected 'child' question.

Limited Save

• Not possible as random questions should not be used in summative exams.

Standard Setting

• Not possible
