Effectiveness of Localized Context-Based STEM Education Approach on Teaching Science 6

Abstract

This study employed a one-group pretest–posttest experimental design to determine the effectiveness of a localized context-based STEM education approach in enhancing the conceptual understanding of Grade 6 learners at Sultan Naga Dimaporo Memorial Integrated School (SNDMIS), Lanao del Norte. Thirty-seven (37) pupils participated in the study during the Academic Year 2025–2026. A 20-item multiple-choice test aligned with the Science 6 curriculum was administered before and after the intervention. Data were analyzed using frequency, percentage, mean, and paired-sample t-test. Results revealed a significant improvement in learners’ performance, with mean scores increasing from 13.51 (pretest) to 16.22 (posttest). Statistical analysis confirmed a significant difference between scores (t = –9.50, p < 0.05), indicating that the intervention contributed to enhanced conceptual understanding. Learners also demonstrated high engagement (grand weighted mean = 2.64), particularly in collaborative and hands-on activities. As part of the intervention, pupils designed a Coral Reef Water Cleaner prototype using recyclable materials. Evaluation results (90.8%–96.4%) reflected outstanding performance in creativity, functionality, and teamwork. These findings suggest that localized context-based STEM instruction enhances academic performance, engagement, and real-world application of scientific concepts.
