Delayed feedback can make a useful correction arrive after the thinking has gone cold.
When correction arrives hours later, the mental context is gone. The learner remembers the answer they got wrong, but not the thinking path that produced it.
The Tangi experience we are building keeps feedback inside the attempt, while the child can still remember what they were trying to do.
Why timing matters more than volume
Most students do not need more explanation. They need better timing.
A short prompt at the moment of confusion can keep the same mistake from repeating without overwhelming the learner.
The aim is a clear path forward without replacing the thinking.
What personalized feedback should adapt to
Personalization should follow behavior, not labels.
Error pattern. Is the learner repeating the same step-level mistake or making random slips?
Visible behavior. Are attempts slowing down, repeating, or stopping early?
Recovery speed. After a hint, do they continue independently or need repeated intervention?
Tangi is being designed to adjust hint type, pacing, and difficulty from those visible signals.
Keep feedback lightweight and actionable
Long explanations in the middle of work often break focus.
Use one action at a time. Highlight the incorrect operation, suggest the next transformation, and let the student complete the step.
This keeps ownership with the learner while still preventing error loops.
Track progress through mistake quality
Not all mistakes mean the same thing.
Track whether errors are becoming more advanced, less frequent, and easier to self-correct. That pattern can reveal growth that a single score misses.
Planned parent summaries will make this progression easier to see without exposing every moment of the session.
Build confidence through recovery reps
Students build resilience by recovering from errors, not by avoiding them.
A strong feedback system creates many small recovery reps each session. Make an attempt, get a clear adjustment, apply it, and continue.
Over time, learners stop fearing mistakes because mistakes become part of forward motion.
