Investigation of AI Grammar Checkers on Grammar Learning and Students’ Perception in L2 Writing Context

초록

This study investigates three distinct AI Grammar Checkers (AI GCs) in English writing to assess their impact on grammar enhancement and learners’ perceptions. The study included 125 students divided into three experimental groups, each employing SpellCheckPlus, Virtual Writing Tutor, or Grammarly. The first question pertains to how three AI GCs contribute to grammar learning. While all groups demonstrated improved grammar after using AI GCs, there were no significant discrepancies in the post-test between the groups. That is, no significant variations in improvement were observed across the different GCs. The second question explored learners’ perceptions of the three AI GCs. Results from a questionnaire revealed that all groups exhibited favorable aspects towards the AI GCs, highlighting benefits in active involvement, error identification, convenience of use, easiness, and others. However, aspects like interests, motivation to write, and comprehensive feedback demonstrated no substantial changes before and after AI GCs use. Regardless of the benefits and drawbacks of the three AI GCs of the study, Grammarly's ability to enhance learning stood out in particular in terms of error identification, writing feedback, and user-friendliness. All groups presented diverse opinions on drawbacks, including accuracy issues, inconvenience, feedback inadequacy, and tool dependency for all three programs.
