Observe, classify, test, rewrite.
Observe
Describe what looks unstable without naming the cause too early.
Classify
Decide whether the likely issue belongs to movement, countershape, spacing, material or composition.
Test
Run a short exercise that changes one variable while keeping the others as stable as possible.
Rewrite
Return to the original form or word and compare the new result with the first attempt.
Why the method avoids long automatic drills
Repetition is useful only when the learner can still notice what is happening. The platform therefore uses shorter sets with explicit comparison points.
Typical session length
Most activities are designed for approximately 20–40 minutes. Learners can stop when attention drops and continue the same diagnostic question later.
Feedback
Worked examples explain one reasonable approach and identify observable features. They do not claim that every stylistic decision has one correct answer.
