Ethnomathematics-Based Interactive Video of Dermo Temple to Enhance Numeracy Skills of Elementary School Students

Since numeracy is an important skill that elementary school students must have, it is necessary to develop learning media to improve this skill. Educational videos using Dermo Temple ethnomathematics can be used as an alternative method of teaching. This study aims to develop and assess the effectiveness of an interactive ethnomathematics-based video of Dermo Temple. It focuses on numeracy as an essential skill for students to tackle mathematical problems. This study employed the 4D development model, conducted at SDN Anggaswangi 2 during the academic year 2023/2024. Data were gathered through interviews, observations, questionnaires, scales, and tests. Based on the research result, it was inferred that i. the ethnomathematics-based video was developed using 4D models until the development stage, ii. the media feasibility test results on the language aspect were 93.33% with very feasible criteria, the media appearance aspect was 87.77% with very feasible criteria, and the material aspect was 86.66% with very feasible criteria, and iii. the practicality of the Dermo Temple ethnomathematics-based video was 83.57% which showed very interesting criteria. For this reason, the interactive video proves to be effective in enhancing numeracy of elementary school students.
