Multi-Module Tree Structures

[iturgeon]

Allow authors to build a tree structure of modules.

Possible Features:

• A module would have a "Next Module" link at the end
• Allow for randomized A/B testing (with weighted percentages?). 50% of students visit A, 50% visit B.
• Allow overall assessment results to dictate which module the student visits next
• Allow scores on specific questions to dictate which module is next
• Allow performance for groups of questions (by tags/classifications/topics) to dictate which module is next.
• Allow for scores and answers anywhere in the tree (not just the previous module) to dictate which module is next
• Students can see a mini-map of their progress
• Maybe allow students to choose their destination from 2-3 options?
• Allow modules to link to other modules via text links in content and feedback. if the target link isn't on the main map of modules, it could appear as an isolated module on the map?
• Allow modules w/ no assessment to link lead into another module
• Allow students to return to the tree at a later time (and resume)

Current Thoughts of how to start:

1. LTI launches to tree (instead of a single lo, a new url? /view-tree/:treeId)
2. Each module is connected at a limited number of points to the tree
   • single entry point
   • single exit point (last content page (no assessment) OR after an assessment)
   • a text link or special chunk for module links (could auto detect module links and launch to them?)
3. On entry/exit of each connection point, the logic of what to do can be held in the tree (A/B, locking, forking, etc). These tree logic nodes can access the student's performance in the tree (module scores, question scores)
4. At some point, the tree's logic nodes can decide to submit the score back to the course
