{"abstract":"This study investigated the effectiveness of ChatGPT as a practice partner for senior high school students to master subject-verb agreement. A quasi-experimental pretest-posttest design was used with 80 senior high school students from Lala Proper Integrated School. Learners used ChatGPT for one hour daily over five consecutive days to answer subject-verb agreement exercises. Grammatical ability was assessed using a teacher-made test before and after the intervention. The mean score increased from 15.6 (pretest “Fair”) to 21.4 (posttest “Good”), yielding a mean difference of 6.00 points. A Wilcoxon signed-rank test was conducted due to non-normality.
