Deep Practice · the session

One focused session.
The questions that mattered.

Not an open-ended chatbot. Deep Practice brings up to ten questions the student got wrong into one 15–20 min voice session on a shared whiteboard. It guides the student to each fix, then writes the result back to their learning profile.

That last term — what times 6x gives you 18x?
6x(2x + 3) = 12x² + 18x

It asks. It never just tells.
Every prompt walks the student one step closer to the fix — a question, never the answer. The understanding has to be theirs.
From homework to a fixed concept

From a wrong answer last night to a fixed concept by tomorrow.

The session has a beginning and an end. It starts where the mistakes already are, and finishes by writing what it learned back into the map.

01
The error logbook

Questions the student got wrong in homework, collected and tagged to their knowledge points — with up to ten brought into the session.

02
Open by voice

A shared whiteboard, talked through out loud — not a video to watch.

03
A real back-and-forth

The student explains; the AI tutor questions and responds. They work through the problem until the student reaches the fix. One-to-one guidance, not one-way playback.

04
Written back

What moved and what's still shaky, written back into the student's learning profile.

Why it isn't a chatbot

A chatbot opens blank. This one already knows where you're stuck.

Same screen, two different things underneath. One starts from nothing every time. The other starts from everything it already knows about this student.

A generic chatbot
STARTS FROM ZERO
Hi! What would you like help with today?
Um… honestly, I don't get any of this.
○No history · no map · it has to ask.

OPENS KNOWING THIS STUDENT
You're on quadratics. Last night you slipped on the last term of 12x² + 18x — you tend to rush when it's late. Let's start right there.
Yes — let's start right there!

Real teaching, not Q&A

It doesn't just answer.
It works out how to teach you.

Behind the conversation, a mind is deciding how to teach you — when to ask, when to push, whether you've really got it.

STEP 1
Reads you
A doubled term on the board — and your profile says you rush when tired. So: a slip, not a gap.
STEP 2
Picks the move
Won't hand you the answer. Asks one question so you find it.
→“What times 6x makes 18x?”
STEP 3
Checks it's real
First try, no hesitation — real understanding, not a lucky guess. Move on.
What the session leaves behind

The session ends. The profile doesn't.

A 15–20 minute voice session becomes a lasting update to the student's learning profile.

A tutor you talk with — that knows how to teach.

A real two-way conversation by voice on a shared whiteboard — with a mind behind every line, working out how to teach you, not just what to answer.
