Mistake Notebook System Dashboard

What This Is

If you keep making the same mistakes, it’s not “forgetfulness.”
It’s a missing review system — and this dashboard installs it.

This is a repair system, not a mistake collection.
It turns scattered corrections into a weekly redesign loop that actually changes your Japanese.

You will capture only the errors that matter,
run a weekly redesign loop,
and track one metric that proves your study is finally working.

Who This Is For

This system is for learners who:

• Study regularly but keep repeating the same errors
• Get corrections (from tutors, AI, or content) but nothing sticks
• Have notes, but no review loop that forces improvement
• Want one simple metric to confirm their system is working

Who This Is Not For

This system is not for learners who:

• Want a grammar textbook or a large list of rules
• Prefer logging everything (this system is intentionally minimal)
• Are not willing to do a weekly 10–15 minute review

Failure Modes

(Common Ways a Learning System Breaks)

• The same mistake repeats across weeks
• Corrections are collected but never redesigned into practice
• Too many minor errors are logged, hiding what matters
• Corrections never become usable chunks in speaking

Diagnosis (Yes / No)

Answer quickly:

• Do you keep seeing the same mistake after you’ve “learned” it?
• Do you have many notes but no weekly review ritual?
• Do you write corrections but rarely reuse them in output?
• Do you log too much and can’t tell what matters?

If you answered “Yes” to any of these,
your review system is missing or miswired — and this dashboard repairs it.

What You’ll Build

A Notion dashboard that runs a clean loop:

Capture only what matters → find repeats → choose ONE redesign → measure weekly

You will be able to:

• Log one high-signal mistake per day (maximum)
• Save only three drivers of improvement:
  Correction / Natural Alternative / Chunk to Save
• Run a weekly review that forces one redesign decision
• Track one success metric that proves progress

Success Metric (One Number Only)

Repeat Rate = repeat mistakes ÷ total mistakes (weekly)

If your learning system is working,
Repeat Rate goes down over time.

Redesign

(One-Page Repair Template)

Each week, you will fill out:

• Cause (why it repeats)
• Fix (rule or constraint)
• Next Action (one action only)
• Proof: Repeat Rate ↓

What’s Inside

• Notion template
  (Dashboard + Mistake Log + Weekly Reviews)
• Weekly Review template
  (default steps, repeatable)
• Quick Start PDF
  (5 minutes to start, daily + weekly rules)

How to Use

(Fastest Path)

1. Add one entry in the Mistake Log today (keep it short)
2. Check Is Repeat if it’s recurring
3. Fill #1 Correction / Natural Alternative / Chunk to Save
4. Once a week, open Weekly Reviews → New
5. Link only important mistakes and make ONE redesign decision

Next Step (Handoff)

When you have chunks worth saving,
move into the AI Japanese Coach Prompt Library
to run minimal role-play → one correction → chunk saving on repeat.
