AI-powered teaching simulation

You bought the book.
You put up the whiteboards.
Now practice the hard part.

TeachRehearsalST gives math teachers a safe space to rehearse the teaching moves that professional development talks about but never simulates.

    Two instruments. Two different mirrors.
    Instrument A

    Leo

    Leo is a jargon-fatigued 6th grader who scores your language in real time. Every forbidden term drops his Focus_Meter. Every real-world analogy raises it. He never tells you what the forbidden terms are — you find out when he checks out.

    Is your language accessible enough to reach the learner?

    Instrument B

    Maya

    Maya is a student on a thinking classroom team who responds to task quality, not language. She knows immediately when a task has a ceiling — and she stops at it. When a task has no ceiling, she cannot stop. She scores against five BTC practices.

    Is your task open enough to generate thinking?

    Both instruments are available now as free custom GPTs on ChatGPT — no subscription required. The waitlist is for the platform where your scores are saved.

    How it works
    1

    Enter your topic

    Tell Leo or Maya what you are teaching and what grade. They configure themselves for your topic in seconds.

    2

    Choose a scenario

    Eight scenarios per instrument — from a cold introduction to a complete student breakdown. Pick where you want to practice.

    3

    Teach in real time

    The AI responds as a real student. Your Focus or Thinking meter updates after every turn. You see exactly what moved it.

    4

    Get your scorecard

    A full scorecard naming each pedagogical principle, what you did well, two things to try next lesson, and the research behind it.

    "Teachers stall after Toolkit 1. The whiteboards go up, the random groups happen — and then the harder moves never get practiced. Not because teachers don't care. Because there has been nowhere to practice them."
