A new research paper published on arXiv introduces a novel LLM-correction pipeline designed to differentiate between grammatical accuracy and idiomatic naturalness in English writing by Japanese learners. The study analyzed 3,830 writing samples, identifying specific areas where students struggle with accuracy, such as definite articles and third-person singular '-s', and areas where they overuse or underuse idiomatic expressions, like '-ing' forms and modal verbs. This framework aims to provide more targeted pedagogical feedback to educators, helping them address whether learner difficulties stem from inaccurate execution, avoidance of complex structures, or overreliance on native language patterns.
