<![CDATA[The integration of digital technology and culturally relevant learning resources is essential for strengthening elementary students’ literacy and numeracy skills within the Merdeka Curriculum. However, learning in primary schools remains largely dependent on conventional teaching materials, which provide limited interactive and contextual learning experiences. This study aimed to develop and evaluate the validity, practicality, and effectiveness of an interactive digital flipbook based on Indonesian folklore (Legenda Nusantara) for improving the Indonesian language literacy and numeracy skills of third-grade elementary school students. This Research and Development (R&D) study employed the ADDIE model and involved 32 third-grade students at SDN Wedoro, Waru, Sidoarjo. Data were collected through expert validation, teacher and student response questionnaires, observations, and pretest–posttest assessments. Data were analyzed using descriptive statistics, normalized gain (N-gain), and a paired-sample t-test. The results showed that the developed flipbook achieved a validity score of 94.3%. Its practicality was supported by teacher and student response scores of 96.1% and 94.8%, respectively, indicating that the media was highly practical for classroom use. Students’ Indonesian language literacy scores increased from 66.25 to 87.81, while numeracy scores improved from 64.53 to 85.97. The average N-gain of 0.71 was categorized as high, and the paired-sample t-test indicated a statistically significant improvement (p < .001). These findings indicate that the interactive digital flipbook provides a valid and practical learning resource and contributes to improving students’ literacy and numeracy skills through contextual and culturally relevant learning based on Indonesian folklore. The developed media can therefore be considered an innovative learning resource to support literacy and numeracy development in elementary education.]]>
