Abstract
This quasi-experimental research investigated the effect of the Mathrix Sense Intervention on enhancing multiplication fact recall among Grade 7 learners at Dadiangas North High School during School Year 2019–2020. The intervention included four key instructional components: developing number sense, applying multiplication strategies, using flashcards, and integrating the Mathrix mobile learning application. Sixty learners were purposively selected and equally divided into experimental and control groups. The control group received traditional instruction, while the experimental group was taught using the Mathrix Sense Intervention. Both groups completed pretests and posttests aligned with the Most Essential Learning Competencies (MELCs) in Mathematics. Pretest results showed no significant difference between groups, indicating similar baseline knowledge. However, posttest scores revealed a significant improvement in the performance of the experimental group compared to the control group, with a large effect size based on Cohen’s d. These findings demonstrate that the Mathrix Sense Intervention had a positive effect on learners’ ability to recall multiplication facts. Therefore, this study recommends adopting the Mathrix Sense Intervention as a valuable approach for strengthening foundational skills in Mathematics, particularly in multiplication, among Grade 7 learners.
