This study aimed to develop localized and contextualized electronic listening (e-listening) materials as a strategy to improve learners' listening skills in the school year 2025-2026. With the increasing use of digital learning platforms, adapting listening materials to learners' cultural, linguistic, and contextual backgrounds has become essential. The study employed a developmental research method, and a purposive sampling technique was used in determining the respondents of the study. The material that was being used was intended for their specific grade level, and the ASSURE model was adapted to create the e-listening materials. The study's total sample population included 27 students. A dependent sample T-test was used to assess the significant difference in the listening skills of Grade IV pupils before and after using the developed materials. Mean and standard deviation were used to determine the level of listening skills of Grade IV learners before and after the utilization of the developed materials. Results revealed that the developed instructional materials are highly acceptable, as indicated by the learning resource evaluation outcomes. Furthermore, the effectiveness of the materials was measured using a pretest–posttest design. Based on the findings, the calculated statistic t-test was -15.533, and the p-value was .000 when localized and contextualized e-listening materials were used. It means that there was a significant difference because the p-value was below the alpha of 0.05. The results demonstrated that the localized and contextualized e-listening materials were effective in elevating learners' listening skills from low to high levels, indicating the positive impact of the instructional approach. The study concludes that developing localized, contextualized e-listening materials enhances language learning and promotes meaningful education by integrating cultural familiarity with digital tools, thereby creating more effective e-listening content.
