Analysis of Accuracy and Grammatical Acquisition through Grammarly's Immediate Feedback: A Study on Autonomous Correction of Subject-Verb Agreement and Verb Conjugation in A2 Level English Students
Year: 2026
Type: article
Study design: Clinical Trial
Abstract: This study examines the impact of immediate automated feedback on the grammatical accuracy and autonomous correction skills of EFL students. Specifically, it focuses on Subject-Verb Agreement (SVA) and Verb Conjugation (VC) among 51 undergraduate students at the A2 proficiency level. Using a quantitative approach with a pretest-posttest design and observation logs, the research evaluated the effectiveness of AI-driven corrective feedback through the Grammarly software. The statistical analysis revealed a significant improvement in student performance, with the mean total score increasing from 4.96 to 7.55 (p .001). Error frequencies decreased by 56.3% for SVA and 60.5% for VC. Furthermore, the observation data indicated high levels of engagement, with 80.4% of participants demonstrating successful autonomous revision. These findings suggest that immediate automated feedback serves as a vital digital scaffold, enabling learners to transition from passive error recognition to active linguistic self-regulation. The study concludes that integrating AI tools into the EFL curriculum not only enhances grammatical precision but also empowers students to take ownership of their learning process, bridging the gap between instructional feedback and independent mastery in the Ecuadorian higher education context.
