Curriculum decomposition
Curriculum decomposition turns learning objectives into an ordered set of teachable decisions, concepts and practices, preserving prerequisites and transfer instead of generating a pile of loosely related lessons.
Mental model
A curriculum is a dependency-aware learning path. Decomposition asks what the learner must understand first, what decision each unit enables, what practice proves the transition and what can be deferred without breaking later learning.
Why it matters
AI makes lesson production cheap, so curriculum quality increasingly depends on sequencing and omission. If every interesting topic becomes a unit, learners receive breadth without a usable mental model. Decomposition keeps the course aligned to outcomes and makes content generation subordinate to a coherent learning progression.
01
Decompose backward from outcome and prerequisite
Start with the final learner decision or artifact, identify the concepts required to produce it, then arrange them by dependency rather than by source-material order. Give each unit one clear transition: what becomes possible after this unit that was not possible before? Attach practice where the transition needs evidence, and merge or defer topics that do not create a distinct learning step.
02
Example: an RAG course mirrors a documentation table of contents
A course copies docs into chapters on embeddings, vector databases, chunking, reranking and evaluation. Learners know terms but cannot diagnose a failed pipeline. Re-decomposition starts from the task 'identify why evidence was missed or noisy', then orders retrieval units, ranking, authority and evaluation around that decision with a failure lab as evidence.
Common failure modes
- Using source-document order as curriculum order.
- Creating one lesson per topic even when several do not represent distinct learner transitions.
- Adding practice activities that are engaging but do not prove the stated objective.
Engineering heuristics
- Sequence by prerequisite and learner decision, not author convenience.
- Give each unit a distinct observable learning transition.
- Merge or defer material that does not change what the learner can do.
Takeaways
- 01Curriculum is an ordered dependency system, not a content inventory.
- 02Cheap generation makes omission and sequencing more important.
- 03A good unit earns its place by enabling a distinct learner transition.
