<![CDATA[This study aims to improve the learning outcomes of second-grade elementary students on addition without carrying techniques through the application of a Problem-Based Learning (PBL) model based on TPACK, supported by interactive media Wordwall and educational videos. The research used a Classroom Action Research (CAR) method comprising two cycles, with each cycle involving planning, action, observation, and reflection stages. The subjects were 38 second-grade students from SD Inpres 3 Birobuli. Data was collected through observation, learning outcome tests, and documentation. The results indicate an improvement in student learning outcomes from the first cycle to the second. In the first cycle, the percentage of students meeting learning mastery reached 65.8%, which increased to 86.8% in the second cycle. The use of interactive media Wordwall and instructional videos effectively helped students grasp the concept of addition without carrying techniques. Furthermore, the PBL model based on TPACK enhanced students’ activity and participation, as seen in their high engagement in discussions and collaborative problem-solving activities during the lessons. This study demonstrates that implementing a TPACK-based PBL approach with interactive media support not only improves learning outcomes but also helps students develop collaborative skills and critical thinking. The integration of technology through interactive media creates a more engaging and effective learning environment, which is relevant to the demands of digital-era education. Thus, this approach is recommended for educators to implement in teaching mathematics or other subjects at the elementary level to enhance learning quality and student achievement.]]>
