Every instructor knows the moment: a child has been working on the same few concepts for two weeks, the accuracy line is flat, and the honest question is what exactly should I change? Until now, apps answered with silence — the same exercise, again, tomorrow.
Interlaza records every single trial: what was shown, what was chosen, how long it took, how much help was active. The new Program Advisor puts that data to work.
What it watches
For each concept a child is learning, the Advisor tracks the learning trajectory our mastery model estimates trial by trial. From that it distinguishes four situations:
- Progressing — the estimate keeps climbing. No action needed, and the Advisor stays silent.
- Plateau — plenty of practice, but the estimate has gone flat well below mastery.
- Regression — recent sessions are clearly worse than the ones before.
- Mastered — done; the spaced review system takes over from here.
It also watches two things beyond accuracy: signs of disengagement across recent sessions (rushed answers, long pauses), and whether the recorded reward preferences have gone stale — at this age, what motivates a child can change in weeks.
What it proposes
The Advisor never just says “something is wrong.” Each finding comes with one concrete, one-tap change:
- Insert an easier step first. If “bird” is stuck at a harder level and the child never actually mastered matching identical birds, the Advisor inserts a short identity-matching stage right before the current one. Prerequisites first — the oldest rule in structured teaching, now applied automatically.
- Increase help. If a concept is flat at the first level, one tap raises the errorless support so the child succeeds more before the help fades again.
- Practice with real objects for a while. If the data shows growing disengagement, the Advisor suggests moving sessions off the screen: you present real objects — the real spoon, the real toy dog — and record the child’s responses on the tablet. Everything learned on screen has to reach the real world eventually; sometimes the fastest way forward is to go there directly, and come back to the screen re-engaged. The tablet keeps recording data either way, so nothing is lost.
- Refresh the rewards. When preferences are more than a month old, the Advisor suggests re-running the preference assessment.
What it never does
Two hard rules. First, the Advisor suggests; you decide — nothing changes without your tap, and every applied change is logged. Second, it never silently edits a route that several students share: those changes remain a deliberate decision in the route editor.
You’ll find the Advisor’s suggestions in two places: the Needs Attention feed on your home screen, and a panel inside each student’s profile. If there is nothing worth saying, you see nothing at all — silence means progress.
