A lot of apps respond to a wrong answer with more questions on the same topic. That works if the mistake was a slip — it doesn't work if the child never understood the underlying concept in the first place.

That approach assumes the mistake was a one-off slip rather than a genuine gap in understanding. When the actual problem is a missing concept — the child doesn't understand why you carry a digit, or why a fraction's denominator matters — repeating similar questions just produces more wrong answers on the same broken foundation, often without anyone noticing what the real issue is.
Lumi's remediation system identifies which underlying concept a wrong answer points to, rather than treating the question topic itself as the only relevant data point.
Once the actual concept gap is identified, Lumi re-teaches that specific concept directly, rather than just serving up another similar practice question and hoping repetition closes the gap on its own.
Math and reading especially build cumulatively — an unaddressed gap early on tends to resurface and compound in later lessons. Root-cause remediation addresses the gap when it first appears rather than letting it carry forward.
Getting the same type of question wrong repeatedly, with no new explanation offered, can be discouraging for a child. Remediation that actually re-teaches the concept breaks that loop.
The same root-cause remediation approach is used across math, ELA, science, and social studies, rather than being a feature specific to one subject.

The distinction matters when the underlying issue is conceptual rather than a lack of repetition; in that case, more of the same kind of question doesn't address the actual cause.
If you've noticed a child stuck in a loop of getting a certain type of question wrong repeatedly with no apparent improvement, that's often a sign the platform is responding to symptoms (wrong answers) rather than the cause (a specific concept never fully clicking) — worth checking whether remediation actually re-teaches, or just repeats.
More practice repeats similar questions on the same topic; remediation identifies the specific underlying concept behind a mistake and re-teaches that concept directly.
The lesson traces a mistake back to the underlying concept it depends on, rather than treating the question topic alone as the only signal.
It happens automatically as part of the lesson flow whenever a wrong answer occurs.
It applies across math, ELA, science, and social studies.
Yes, addressing a conceptual gap when it first appears helps prevent it from compounding in later, more advanced material that depends on it.
