What is this? (plain English)

CoinQuest K-2 Sampler (Penny Island)

A short money game for kids in kindergarten through 2nd grade.

The AI teacher is Copper — a 5-year-old boy character in a golden-dollar scout cap.

Step-by-step:

  1. Step 1. Tap to start — Copper greets you with sound
  2. Step 2. See 5 questions about real US coins (penny, nickel, dime, quarter)
  3. Step 3. Pick your answer — right = Copper celebrates, wrong = try again with Copper showing you why
  4. Step 4. Can't skip — must answer before Next works
  5. Step 5. See your score + what Copper noticed you're good at / need practice on

The AI behind it (CALE): The Cognitive Adaptive Learning Engine watches every click, every wrong answer, and every retry — figures out where you're stuck and adjusts the next question to teach you, not just grade you.

🔬 CALE Error Classification

CoinQuest uses CALE (Classify, Analyze, Learn, Evolve) to understand WHY students get answers wrong -- not just that they did.

⚡ Careless Error

Detection: Student answered quickly (<5 seconds) and has gotten similar questions right before.
Response: Gentle reminder. No re-teaching needed. "Slow down and double-check!"
Example: Student knows 5+3=8 but rushes and taps 7.

❌ Misconception

Detection: Student consistently picks the same wrong pattern (e.g., always adds when should subtract).
Response: Targeted mini-lesson addressing the specific misconception.
Example: Student thinks "more coins" always means "richer" regardless of coin value.

😶 Conceptual Gap

Detection: Student takes a long time (>20 seconds) and still gets it wrong. First time seeing this concept.
Response: Full concept introduction with visuals, story, and guided practice.
Example: Student has never encountered the idea of "change" from a purchase.

💤 Knowledge Decay

Detection: Student answered correctly weeks ago but now gets it wrong. Spaced repetition flag.
Response: Quick refresher, not full re-teach. Schedule more frequent review.
Example: Student knew coin values last month but forgot that a dime = 10 cents.

How It Works in the Quiz

When you answer quiz questions, CALE classifies your response based on:
Response Time -- Fast wrong answers suggest carelessness. Slow wrong answers suggest gaps.
Answer Pattern -- Which wrong answer you pick reveals the type of confusion.
History -- In the full product, CALE tracks every student over time to detect decay vs. new gaps.
This sampler simulates CALE classification so teachers can see the system in action.
