Integrating Multimodalities in Strengthening Students’ EFL Grammar Knowledge

This study investigates the integration of multimodal learning platforms in enhancing students' English grammar knowledge in an EFL context.The research aimed to compare the effectiveness of two digital platforms-WhatsApp (WA) and Google Classroom (GC)-in supporting grammar instruction through multimodal resources such as text, audio, and visual materials.Employing a quasiexperimental design, fifty undergraduate students were purposively assigned to two groups: the experimental group learned through WA, while the control group used GC.Both groups received identical instructional content and activities, and data were collected through pre-and post-tests to measure their grammar achievement.Statistical analysis using the independent-sample t-test indicated significant improvement in both groups' post-test scores, demonstrating that learning through multimodal platforms effectively enhances grammar mastery.Although the mean score of the WA group was slightly higher than that of the GC group, the difference was not statistically significant.These findings suggest that integrating multimodal approaches through digital platforms facilitates students' engagement and comprehension of grammatical structures.The study implies that English teachers should adopt diverse multimodal strategies in digital learning environments to promote active learning and deepen students' understanding of grammar concepts.
