DEVELOPMENT AND VALIDATION OF STRATEGIC INTERVENTION MATERIAL IN SCIENCE-8

Author(s) JULIET A CARLOS

Abstract This study focused on the development and validation of a Strategic Intervention Material (SIM) in Science 8 designed to enhance classroom instruction by improving learner engagement, comprehension, and motivation in scientific learning. Conducted at Pio Dalim Memorial School of Arts and Trades in Eva, Calanasan, Apayao during the school year 2024–2025, the research employed a developmental-evaluative design. The SIM was localized, curriculum-aligned, and pedagogically structured based on the competencies of the K to 12 Science curriculum. Its quality was assessed by teacher-experts in terms of content relevance, face validity, presentation and organization, and accuracy and currency of information.
Findings revealed that the teacher-evaluators rated the SIM as very impactful across all dimensions, affirming its appropriateness, clarity, and alignment with learning standards. Minor recommendations were noted regarding typographical accuracy and print formatting. Learner feedback indicated a highly favorable attitude toward the SIM, citing increased interest, improved comprehension of difficult science concepts, greater motivation, and appreciation for its visual elements and clarity of content. However, some students identified challenges such as unfamiliar vocabulary and the need for clearer instructions.
Feedback on usability emphasized the need for further enhancements, including the provision of a teacher’s guide, inclusion of performance-based tasks, and additional vocabulary support. Despite these technical and instructional recommendations, both teachers and students acknowledged the SIM’s effectiveness as a supplementary resource in science instruction. The study concluded that, with minor refinements, the developed SIM held strong potential for broader application in junior high school science education.
