This article covers initialization options specific to Item Branching activities. They are a lightweight form of dynamic assessment, with conditional branches pre-configured in the activity definition. For more precise adaptive algorithms relying on questions with calibrated difficulty see the Item and Testlet Adaptive assessments. You can also refer to the knowledge base article about Adaptive and Dynamic Assessments.
Note: when designing the tree for Item branching, you cannot use Items more than once, i.e. Items cannot be re-used.
Type of adaptive behavior.
In itembranching, the next item is selected based on responses to previous items, according to a pre-configured path provided in this configuration.
An item branching assessment comprises an array of steps. Steps can define the reference of items to present to the student when visited, or decisions to select which branch to visit next.
Only item steps result in items being presented to the student, decision steps are executed in the backend until the next item step is visited.
