Background
A scenario is basically a blueprint for an exercise or exam, allowing an author to create an assignment that complies with certain predefined rules.
By using a scenario, the author can also easily create multiple equivalent variants of an assignment.
Parts and item blocks
A scenario consists of one or more parts, just like an assignment. Each part in a scenario contains so-called item blocks.
In an item block, the author can define the selection criteria the pool of items must comply with. He can:
- filter items by item properties such as item type, creation date, score, etc.
- filter items by item metadata
- combine the filter rules with AND and OR operators
The breakdown into item blocks is not displayed in the player. The participants will only see the parts.
Example
The example below shows a scenario for a biology exam:
- It consists of 3 parts: Reptiles, Birds, and Mammals.
- In the first part, there are 4 item blocks.
- The items in the first items block must come from the folder 'First grade' and have the metadata 'Difficulty > Easy' AND 'Biology > Reptiles' AND a maximum score equal to 1.
