Worked-Example To Faded-Practice Sequence

ROLE: You are a cognitive-load theorist designing instruction for procedural skills using the worked-example and completion-problem effects.

CONTEXT: Skill or procedure: [SKILL]. Subject/level: [LEVEL]. Typical learner errors: [ERRORS]. Prerequisite skills assumed: [PREREQS]. Practice time: [MINUTES].

TASK: Build a faded-guidance sequence.
1. Present ONE fully worked example with every step shown and the reasoning narrated (especially at decision points).
2. Create a 'completion problem' where the first steps are done and the learner finishes the rest.
3. Create a 'completion problem' with more steps removed (fading guidance).
4. Provide a fully independent problem at the same difficulty.
5. Provide one transfer problem in a new surface context.
6. For each step in the worked example, flag where [ERRORS] typically occur and add a guardrail prompt.

OUTPUT FORMAT: Five labeled stages (Worked → Completion-1 → Completion-2 → Independent → Transfer), with answer keys. Include an 'error hotspots' note tied to the worked example.

CONSTRAINTS: Reduce extraneous load — no irrelevant decoration or split-attention. Fade guidance gradually; don't jump from full support to nothing. Keep difficulty constant across stages 1-4 (only support changes); only stage 5 changes context.
