Tutorial authoring

Use this skill when writing, revising, or auditing any document where a reader follows steps to build or achieve something.

Target learner (expertise reversal boundary)

This skill is optimised for beginner-to-intermediate learners encountering the subject for the first or second time. Most multimedia learning principles (Signaling, Pre-training, Personalization, heavy imagery) are strongest in that range and weaken — or reverse — for experts (Kalyuga's expertise reversal effect). If the artefact is an expert-facing quick reference, the author MUST scale back Signaling, Concept density, and hand-holding narrative, and lean on Reference tables. When in doubt, state the target learner explicitly in the document's opening.
