Using grammar beyond substitution drills
Remove model cues gradually and check a changed situation.
Separate substitution from pattern choice
A substitution drill supplies the structure; success does not establish choosing it from an intention. Attempt a model-supported item, then a situation-only response, then two learned situations mixed together. If you can explain the rule but not give an example, add hidden-model generation instead of reread the same explanation.
Change one condition and preserve the first attempt
Change one participant, time or object and apply the pattern in that context. For a repeated particle error, inspect the predicate and noun role before returning to the rule. Change information or question wording when an answer is memorised so the attempt still tests selection.
Recheck in another situation
Keep the first response, reason, revision and next cue. After another study interval, retry without answers. Reduce repeated form errors to two contrastive situations, such as existence versus action, instead of relearn all particles at once. Seek informed feedback on naturalness in open responses.
Example
Original changed cues: 「学校にいます。」versus 「学校で勉強します。」Ask where a person is or where studying happens without naming the required particle.
Check your understanding
Describe an action location without the model, then change it to an existence statement.
Explanation
Explain the place role in both sentences and answer again with a different place.
Find your question
- I can substitute words in Exercise B but cannot choose a pattern in real questions. What should I practise?
- I understand examples but omit particles in my own sentences. How can I practise transfer?
- I made the same particle mistake three times. Should I memorise the rule again or practise contexts?
- I can explain grammar in Chinese but cannot give a Japanese example. Which task should I add?
- I can explain a rule in English but cannot give a Japanese example without looking. How do I check active use?
- I memorised the exact answer to an exercise. How can I create a fair changed-cue check?
