{"abstract":"This study developed a Strategic Intervention Material (SIM) in General Mathematics to enhance the mastery of key competencies among Grade 11 students during the first quarter of the school year 2024-2025. The primary objective was to identify the least mastered competency, evaluate the quality of the crafted SIM, and determine if significant differences existed between teacher and expert validator ratings. Purposive and convenience sampling were used to select nineteen (19) validators, thirteen (13) teachers and six (6) experts from public and private secondary schools in the Division of Isabela. Data were gathered using Project GADGET for item analysis of the first-quarter examination results and a structured 4-point Likert scale questionnaire adopted from the Department of Education Nueva Ecija evaluation rating sheet. Findings indicated that the competency “solving rational equations and inequalities” was the least mastered. The SIM, titled “Let’s Solve It Rationally,” received overall ratings of very satisfactory, with teacher validators providing a mean score of 3.85 and expert validators a mean score of 3.96. The Mann-Whitney U Test revealed no significant difference between teacher and expert evaluations. Based on these results, the study concluded that the SIM is of good quality in terms of its content, format, presentation and organization, and accuracy and up-to-datedness. Recommendations were made to further implement the SIM while incorporating the SOLO Taxonomy and to explore technological enhancements, such as multimedia integration and AI-driven personalization, in future interventions.","abstract_source":"original","authors":["Roselle Domingo","Sheryl Irene Manaligod"],"date":"2025-06-21","doi":"10.70838/pemj.400903","id":5631,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"dca124e06f283eaf1ef8f33c8588ec020278d87159780c1fbccf72f9f0dfe60c","schema":"scimatic-article/1","title":"Least Mastered Competencies in General Mathematics: Basis for the Development of Strategic Intervention Material (SIM)","volume":40}
