Abstract: This study aims to identify the effectiveness of STEM strategies combined with digital modules to develop junior high school students’ mathematical literacy skills. These skills are vital competencies in the contemporary era that need to be strengthened to equip students to face the dynamics of the modern era. The method used was a pre-experimental one-group pretest-posttest design on 30 students of class VII D of SMP Negeri 14 Yogyakarta in the 2024/2025 academic semester. Data were collected using a 4-item mathematical literacy test instrument that measures three indicators: formulate, employ, and interpret & evaluate. Data processing was carried out through normality testing with the Shapiro-Wilk method and paired sample t-test testing. The research findings indicate that the STEM approach based on electronic modules is effective in improving students’ mathematical literacy skills. There was a significant increase from an average pretest score of 35.227 to 77.557 in the posttest with an n-gain value of 0.636 (moderate category). Statistical tests showed a highly significant difference with a t-count of -9.644 and a p-value <0.001. The highest increase was in the interpret & evaluate indicator at 73.58%, followed by employ at 57.57%, and formulate at 34.11%. The integration of STEM in electronic modules successfully bridged abstract mathematical concepts with real-world applications through meaningful and contextual multidisciplinary learning. This approach not only optimizes academic achievement but also fosters crucial 21st-century skills. The study recommends the adoption of an electronic module-based STEM approach as a superior learning strategy for transforming mathematics learning toward an innovative approach that integrates technology.
