A patient conversation gives a learner room to become more accurate.

Accuracy arrives late in learning, after a stretch of being roughly right. Someone getting it half wrong is not failing; they are at the stage where the shape is forming and the details have not landed. Correcting fast and often stops the process, because the learner starts guarding against error rather than trying things. Patience is the condition under which precision can develop.

When someone near you is learning, let a small inaccuracy pass and see whether they find it. Ask a question instead of supplying the fix.
