  "summary": "A wrong answer is useful only when the wrong turn becomes visible.",
  "kind": "protocol",
  "body": "Pair a clearly labelled flawed example with a correct one. Ask where they diverge, why the flawed step fails and how to repair it. Research finds conditional benefits, not a universal advantage from adding errors.",
  "limits": [
    "Novices may need the correct method first. Never leave an incorrect example unlabelled in reference material."

    "Novices may need the correct method first. Never leave an incorrect example unlabelled in reference material."

  "example": "Two calculations look alike, but one applies a percentage to the wrong base. The learner explains the changed denominator before solving a different case.",
  "check": "Can the learner reject the same misconception when its surface details change?",
  "steps": [
    "Choose one realistic misconception and keep unrelated details constant.",
    "Ask the learner to locate and explain the decisive difference.",
    "Provide a checked resolution, then test a new example without labels."
