Investigating the Effectiveness of Localized Context-Based Stem Approach Using 5e Lesson Plan in Teaching Science 3

This study employed an experimental research design, specifically the one-group pre-test and post-test design, to investigate the effectiveness of the 5E Lesson Plan integrated within a localized context-based STEM approach in improving the conceptual understanding and engagement of the Grade 3 – Plato pupils of Sultan Naga Dimaporo Memorial Integrated School (SNDMIS). The respondents of the study were 34 pupils from Section B, officially enrolled during the Academic Year 2025–2026. A 20-item multiple-choice pretest and posttest aligned with the Science 3 curriculum, together with an engagement survey, were administered before and after the intervention to measure pupils’ learning and participation. Data were analyzed using frequency and percentage distribution, weighted mean, Wilcoxon signed-rank test. Results revealed that pretest scores were relatively low, with only a few pupils demonstrating higher achievement, while posttest results showed a remarkable improvement, with most respondents shifting to the “Very Highly Achieved†category. The Wilcoxon signed-rank test confirmed a significant difference between pretest and posttest scores (p = 0.001), indicating that the intervention was effective. Furthermore, survey findings showed that learners were highly engaged during the lessons, enjoying the use of local materials, hands-on group activities, and inquiry-based tasks. The study concludes that integrating the 5E instructional model with localized, context-based STEM instruction significantly enhances pupils’ conceptual understanding, engagement, and problem-solving skills in Science lessons.
