Abstract

This research is an ethnographic study using two AI tools (ChatGPT and Gemini AI) to analyze comparatively the different patterns between Javanese and Sundanese batik. The data was obtained from two AI-generated outputs of two prompts focusing on geometric patterns and transformations. The study used a triangulation process by matching and contrasting AI-generated outcomes with previous literature. The findings reveal that: 1) Javanese batik motifs contain more geometric designs, in the other hand, Sundanese batik tends to use more fluid and organic patterns, and 2) the majority of Javanese batik combines both reflection and rotation, whereas Sundanese batik uses translation and reflection. Math properties from both batik designs are inspired by different cultures. Batik patterns from Java represent values such as balance, organization, and class whereas Sundanese batik expresses Sundanese beliefs about respect for nature. It highlights that traditional arts should be integrated into mathematics teaching to better understand and appreciate their role in various cultures.

Abstract

This study aimed to develop and evaluate an interactive e-book integrating deep learning principles with Garut local wisdom to enhance digital literacy and mathematical critical thinking. Using a research and development (R&D) approach with the ADDIE model and a quasi-experimental design, 73 seventh-grade students participated: 36 in the experimental group and 37 in the control group. Data were collected through mathematical critical thinking tests, digital literacy questionnaires, and expert validation sheets, then analyzed using normalized gain scores, the Mann-Whitney U test, and Cohen’s d. The e-book achieved very high validity (93.33%) and practicality ratings exceeding 95%. The experimental group demonstrated significantly greater gains in mathematical critical thinking (Ng = 0.89) than the control group (Ng = 0.70), with a Cohen’s d of 2.59 indicating a very strong effect. Additionally, 95.35% of students reported improved digital literacy. These findings indicate that culturally grounded interactive e-books can effectively enhance 21st-century skills, providing a replicable framework for integrating local wisdom in mathematics education across diverse cultural contexts.
