      "abstract": "This study examines the effectiveness of Matholia, an interactive learning media, in improving elementary students\u2019 mathematics achievement on fractions. The study was motivated by low student performance that had not met the Minimum Mastery Criteria (MMC) and limited use of media to support abstract concepts. A mixed-methods design was employed, combining a quasi-experimental one-group pretest\u2013posttest model with a case study involving 15 fourth-grade students at an SPK (Satuan Pendidikan Kerja Sama) elementary school in East Jakarta. Data were collected through pretests, posttests, interviews, and observations. Results show a significant improvement, with mean scores increasing from 31.93 (pretest) to 80.70 (posttest). A paired samples t-test indicated a significant difference (t = -11.48; p < 0.001). Matholia supported conceptual understanding through interactive visualization and adaptive practice. This study highlights its integration within the Merdeka Curriculum as a key contribution.",
