Development of Localized Context-Based STEM Education Approach Lesson Exemplar on Teaching Science 5

Abstract

This study utilized an experimental research design, specifically the one-group pre-test and post-test design, to determine the effectiveness of a localized context-based STEM education lesson exemplar in enhancing the conceptual understanding of Grade V learners at Sultan Naga Dimaporo Memorial Integrated School (SNDMIS), Lanao del Norte. Thirty-six (36) Grade V pupils were enrolled during School Year 2025–2026.A 20-item multiple-choice test aligned with the Grade V Science curriculum was administered before and after the intervention. Data were analyzed using frequency and percentage distribution, mean, and the Wilcoxon Signed-Rank Test. Findings showed that pre-test scores were generally low, indicating limited prior understanding of concepts related to the interactions between living and non-living things in estuaries and intertidal zones. After the implementation of the localized STEM lesson exemplar, post-test scores significantly improved. The Wilcoxon test yielded a p-value of 0.000, confirming a significant difference between the pre-test and post-test scores. This result indicates that the localized context-based STEM approach effectively enhanced learners’ conceptual understanding
