The Pythagorean theorem and the ability to abstract are two important elements in mathematics, but they actually become problems. Therefore, this study aims to determine the impact of digital learning materials based on deep learning integrated with Batak culture on students’ abstraction abilities in Pythagorean theorem learning. This study used the ADDIE model development design. The participants in the study were 32 students (16 boys and 16 girls, aged 13-14 years) from one of the junior high schools in Medan, Indonesia. The instruments in the study were digital teaching materials and student abstraction ability tests. Data were analyzed using qualitative data analysis and nonparametric statistics. The research results revealed that the integration of culture within the framework of deep learning proved essential in digital teaching materials. The implementation ran smoothly because the materials were developed based on the needs of the students and incorporated cultural elements, making them familiar to the students. The research findings also revealed that the digital teaching materials were able to optimize students’ abstraction abilities, with male students showing better abstraction skills than female students. The study recommended that future researchers examine the factors that caused male students to be more dominant in abstraction. © 2025 by Author/s and Licensed by Lectito Publications, Netherlands.
