Abstract

This study investigated the effectiveness of Kotobee-based English learning modules in enhancing grammar competencies among 25 Grade 6 learners at Anomar Elementary School, Surigao City, Philippines. Employing a One Group Pretest-Posttest design, the study utilized pre- and post-tests focusing on verb tenses, conjunctions, and adverbs. Data were analyzed using descriptive statistics and the Wilcoxon Signed-Rank Test. Findings revealed that pre-intervention, pupils were "Less Competent" in verb tenses and adverbs, and "Not Competent" in conjunctions. Post-intervention, they advanced to "Competent" in verb tenses and adverbs, and "Less Competent" in conjunctions. The modules' development followed a systematic process, aligning with DepEd MELCs and requiring Kotobee Author expertise. Crucially, a significant difference and mean gain were observed in overall grammar competency before and after module use. The study concludes that Kotobee-based interactive learning modules effectively improved Grade 6 pupils' grammar competence, particularly in verb tenses and adverbs, demonstrating a positive, statistically significant impact on their learning outcomes. While improvement for conjunctions was noted, further intervention might be beneficial for achieving higher mastery.
