エラーログ概念マップ: 間違いを次の学習計画に変える
小テスト、模試、演習、プロジェクトのミスを概念マップで分析する実践ガイド。
A simple error log records what went wrong; this localized article reframes it as a concept map for action. Start with the guide, adapt a template, and build the first version in the editor. For shared context, see concept map, metacognition, and testing effect.
要約
- Sort each mistake into 5 practical types: 記憶, 概念, 手順, 手がかり, 転移.
- Keep one review map to 12-20 nodes.
- Connect every mistake to cause, missing prerequisite, action, and retest time.
- Rebuild the weakest branch after 48 hours.
"A useful error log changes the next study session within 10 minutes; otherwise it is only storage."
— Hommer Zhao, Knowledge Mapping Researcher
Method
The focus question is: why did these mistakes happen, and which pattern should be repaired first? 記憶 errors need 5-8 retrieval prompts. 概念 errors need clearer relationship labels. 手順 errors need a 4-7 step checklist. 手がかり errors need contrast examples. 転移 errors need 3 new contexts.
| Type | Signal | Repair | Retest |
|---|---|---|---|
| 記憶 | missing answer | 5-8 prompts | 24-48 h |
| 概念 | wrong relation | redraw branch | 48 h |
| 手順 | skipped step | checklist | next set |
| 手がかり | distractor | paired examples | 24 h |
| 転移 | new format fails | 3 variants | 72 h |
Examples and template
In science, several wrong answers may share one hidden relation: energy, gradient, or structure. In math, many mistakes after a correct first step point to execution rather than theory. In a team review, one unclear owner can create several downstream symptoms.
"When a learner brings 30 mistakes, I look for the 3 repeated causes because they decide the next 90 minutes."
— Hommer Zhao, Knowledge Mapping Researcher
Use this structure: evidence, cause, prerequisite, action, retest. Pair it with retrieval practice, knowledge gap analysis, and use cases.
"For teams, the first repeated handoff error often matters more than five isolated symptoms."

FAQ
How many mistakes belong on one map?
1回の学習では5から15個、週次レビューでは最大30個のミスを扱います。
Is this better than a spreadsheet?
Use a spreadsheet for 50 or more rows; use a map to explain why 3-8 errors share one cause.
How long should the first map take?
Plan 25-45 minutes: 10 for sorting, 20 for mapping, and 5 for retest choices.
What if the cause is unclear?
Mark it uncertain and add 2 counterexamples before asking for feedback.
Can it work for essays or projects?
Yes. Map claims, evidence, structure, citations, ownership, and decision rules.
