A cluster represents a set of questions from which one or more may be randomly chosen. Clusters should be completed with an End of Cluster page for best results (otherwise they treat the End of Lesson as the End of Cluster). Questions within a cluster are randomly selected by choosing "Random Question within a Cluster" as a jump. Questions within a cluster may either link to the End of Cluster to exit the cluster, or jump to an unseen question within the cluster, or jump to any other page in the lesson. This also enables the creation of scenarios with a random element using the lesson module.

A cluster in the lesson works as if you had a random question quiz inside your lesson. If you have for example a set of 6 questions / a set of 6 pages inside your lesson AND you would like each student to go through ONLY two of these 6 pages, then you can use Cluster to arrange that.

What are clusters?

A cluster represents a set of questions from which one or more may be randomly chosen. Clusters should be completed with an End of Cluster page for best results (otherwise they treat the End of Lesson as the End of Cluster). Questions within a cluster are randomly selected by choosing "Random Question within a Cluster" as a jump. Questions within a cluster may either link to the End of Cluster to exit the cluster, or jump to an unseen question within the cluster, or jump to any other page in the lesson. This also enables the creation of scenarios with a random element using the lesson module.

Sub-Clusters

Clusters can contain sub-clusters by using Branch Tables and End of Branches. To implement this, set up a cluster as normal with a Cluster page followed by question pages (with the linking set up the same as above) and ended with an End of Cluster page. To set up a sub-cluster, wrap a group of questions with a Branch Table and an End of Branch. Neither the content nor the jumps of the Branch Table and the End of Branch have importance. Rather the two pages act as markers for the sub-cluster within the main cluster. When the student attempts the lesson, only one random question page within the sub-cluster will be displayed to the student.
