Improvement of Students’ Mathematical Communication Skills Using Culture-Based Webtoon Digital Comic Learning Media

Digital technology-based learning media is an effective tool in the development of modern education. Despite the potential, several schools have not fully implemented this tool in the learning process. For example, the competence of Indonesian students in mathematics is ranked 68th out of 81 participating countries in PISA 2022. Therefore, this study aimed to develop web-based comic in education for generation z or i-gen students using Indonesian cultural heritage. The study procedures were carried out based on the method proposed by Plomp as well as the development model. The results showed that learning media developed was valid with scores of 4.4 and 4.3 for practicality and effectiveness, respectively. In addition, 86.11% of students achieved Minimum Completeness Criteria (KKM), with 97.7% providing a positive response regarding Webtoon digital comic. The findings also revealed a significant increase in students' mathematical communication skills after the intervention, as evidenced by changes in each indicator. Based on these results, Webtoon digital comic had the potential to be developed for learning different materials and other subjects.
