Implication

Randomized trial evaluates targeted grammar gains in L2 writing with GenAI feedback, indicating potential benefits.

Key Points

The study aims to evaluate the effectiveness of learner-initiated GenAI feedback in improving grammar skills during collaborative second-language writing.
Participants included 36 undergraduates from a two-year English-as-a-foreign-language program in Japan.
A one-group pretest-posttest design assessed grammar performance using multiple-choice tests focusing on tense, pronouns, conjunctions, and articles.
The intervention utilized Collabowrite, which provided form-prioritized feedback and required manual implementation of changes.
Total grammar test scores significantly improved at posttest and delayed posttest compared to pretest, with no significant difference between posttest and delayed posttest.
No clear evidence attributed the improvements directly to GenAI feedback due to the lack of a comparison group.
