<![CDATA[This research was conducted to produce a QR Code-based Pop-Up Book as a learning medium on the topic of the Indonesian National Struggle, intended for fifth-grade students at SDN 1 Wates. Beyond product development, the study also sought to determine the level of validity and practicality of the resulting medium. A Research and Development (R&D) approach following the ADDIE model was employed. Participants consisted of fifth-grade students and teachers at SDN 1 Wates, Tulungagung Regency. Data were gathered using expert validation sheets along with response questionnaires distributed to both students and teachers.The findings revealed that the developed medium obtained validity scores of 95.35% from media experts, 89.2% from material experts, and 97% from language experts, with all three falling into the "highly valid" category. In terms of practicality, student responses reached 88.8% during the small-scale trial and rose to 91.7% in the field trial, while teacher responses recorded a perfect score of 100%, reflecting a very high level of practicality. These results indicate that the QR Code-assisted Pop-Up Book can be considered both valid and practical, making it suitable for use as a supplementary instructional medium for fifth-grade students.]]>
