Culture-based lesson exemplar (CBLE) on least mastered learning competencies in science 4

Abstract

This study presents the development of a Culture-Based Lesson Exemplar (CBLE) in Science 4, strategically tailored to address the least mastered learning competencies, with the aim of elevating learners' proficiency. Employing a Research and Development (R&D) methodology, the research conducted an actual count of Public Grade 4 Science teachers from the Schools Division of Ilocos Norte (SDOIN), Schools Division of the City of Batac (SDCB), and Schools Division Office of Laoag City as its respondents. To address the research objectives, three research instruments were employed: a survey-questionnaire, content validation, and a level of acceptability assessment. The CBLE in Science 4 is meticulously crafted to facilitate teachers' guided comprehension of scientific concepts and enhance Grade 4 pupils' mastery of the subject matter. This instructional material seamlessly integrates local icons, narratives, resources, and scenarios that reflect the rich Ilocano culture while preserving the core scientific concepts. The CBLE underwent rigorous content validation, encompassing objectives, content alignment, values formation, technical attributes, and instructional quality. Furthermore, its level of acceptability was gauged through the input of a group of end-users. The research findings indicate that the proposed CBLE demonstrates very high validity and garners a high level of acceptability. Consequently, this meticulously developed material serves as an invaluable supplementary resource for educators aiming to enhance the mastery, performance, and comprehension of Grade 4 learners in science. The validation process yielded an overall mean rating of 4.75, affirming the practical utility and quality of the developed material for educational purposes.
