This study investigates the role and importance of the ACT approach in teaching writing in the elementary grades. The ACT framework, which integrates activity-based learning, collaboration, and technology, was implemented in an experimental classroom over an eight-week period. A mixed-methods design was employed to examine changes in students’ writing performance, engagement, and attitudes toward writing. The results indicate that students taught through the ACT approach demonstrated significantly higher improvement in writing quality, motivation, and classroom participation compared to those taught using traditional methods. The findings suggest that ACT provides an effective, learner-centered framework for developing writing skills in young learners.
