Item features

Item prerequisites

All item types can have (a set of) any kind of other items as prerequisites. These prerequisites are called required_items. Required items can be configured using the multi-select dropdown in the item properties admin interface.

All required items must be fulfilled in order to gain access to the item with prerequisites.

Fulfillment means:

• For the content types Text and Video: the item must have been visited at least once.
• For the assessment content types Quiz, and Exercise: the item must have been completed with a score of at least 50% (default value) of the maximum points. This percentage can be configured in Xikolo.config.required_assessment_threshold by the platform administrator.

Until all requirements are fulfilled, the learner’s attempt to access a restricted item is interrupted and the current state of the requirements and fulfillment is shown in a callout (see screenshot below). While visiting the item without having all requirements fulfilled, no visit record is created.

Questions from quizzes with item prerequisites are always excluded from the recap questions.

The feature currently comes with a number of limitations:

• Survey quizzes cannot be required items: those items are quizzes that do not have a score, so they can never be fulfilled with the current logic.
• Handling deletion of items which are required somewhere: deleting such items would result in an error for the item with requirements.
• Handling of locked or unpublished items: locked or unpublished items should currently not be required items, since they cannot be fulfilled.
