This study investigates the impact of essay writing and immediate feedback on enhancing students’ grammar skills, specifically in verb tenses. Given the importance of verb tense mastery in effective communication, this research aims to determine the extent to which essay writing frequency, duration, and topic variety, alongside timely and specific feedback, contribute to students’ grammatical accuracy and consistency. Utilizing a correlational research design, the study examines Grade 7 students at Assumption College of Davao, measuring their essay-writing habits, the immediacy and clarity of teacher feedback, and their grammar proficiency. The study supports the Constructivist Theory, emphasizing active engagement, self-regulation, and continuous feedback as essential components of language learning. It concludes that incorporating structured writing tasks with immediate, clear, and specific feedback enhances students’ grammatical competence. Findings reveal that students exhibit a high level of engagement in essay writing, dedicating time to structured activities that allow them to apply grammar rules in meaningful contexts. Furthermore, immediate feedback significantly correlates with improved grammar accuracy, reinforcing correct verb tense usage through timely corrections and detailed explanations. However, the relationship between essay writing alone and grammar proficiency is less pronounced, indicating that writing practice is most effective when paired with constructive feedback. These findings highlight the importance of feedback-driven learning strategies in English instruction and suggest further research into optimizing feedback methods for different writing activities.
