Work backwards from what the learner needs to do

Start with the decision or action the learner must take, then trace back only to the knowledge that serves it.

Why it works

Experts organize knowledge by structure; novices need it organized by use. When an expert works backwards from a concrete outcome — "they need to be able to do X" — it filters the curriculum naturally: everything that does not serve X is cut, and everything that does serve it is prioritized. This reverses the curse’s natural direction of information flow.

How to do it

1. Identify the one or two things the learner must be able to do after this explanation.
2. List every piece of knowledge that directly enables those actions.
3. Cut everything else — context, background, and "interesting" material that does not serve the outcome.
4. Sequence what remains so each piece enables the next, ending at the target action.

Evidence

Backward design (Wiggins & McTighe, Understanding by Design) is an established instructional design principle with wide practitioner support. Formal comparative studies are fewer, but the principle aligns with cognitive load theory and transfer-appropriate processing research. (clinical)

Backward design is widely endorsed in education but most evidence is practitioner-observational rather than from randomized trials.

Common mistake

Including everything the expert considers important rather than only what the learner needs — a curriculum shaped by the expert’s pride of knowledge rather than the learner’s goal.
