Abstract

The teacher's ignorance of the publication of journal articles became the starting point for the problems to be solved so it became the theme raised in this training. The solution provided through this training is material and guidance from the presenters to all participants. The purpose of this training activity is to provide information about articles and journals, as well as the process of submitting articles to accredited national journals, as well as the scope of it to MTs teachers in Garut Regency in particular, and generally to all other participants. The training method used has five stages, including introduction, socialization, training, practice, and monitoring. The subjects of this training are all teachers who are collected in the MGMP MTs Garut Regency, as well as other participants who work as teachers, lecturers, or students on a national scale. The training activities were carried out in two sessions, including material presentation and practical skills. The results of the evaluation form regarding this training activity were very good, all questions received positive responses and answers from all participants. It seems that several teachers have committed to follow up this training activity by trying to write their findings in the form of articles and publish them in the designated accredited national journals. This training concludes that the insights and knowledge conveyed by the presenters in this training activity can open the eyes of all teachers to aspects of scientific publications that so far have never even been glimpsed by teachers.

Abstract

Ethnomathematics serves as a bridge between history and culture with mathematics, playing a crucial role in recognizing that various cultural activities lead to different mathematical concepts. This study aims to describe the historical, philosophical, and mathematical concepts embedded in traditional Papuan houses, including Honai, Kaki Seribu, Rumah Pohon, and Rumsram. The research was conducted at the Papua Ethnic House Tourism and Cultural Park using a qualitative descriptive research method based on ethnography. Data were obtained through observation, interviews, and documentation, and analyzed using data reduction, data presentation, and data verification techniques. The results showed that traditional Papuan houses integrate mathematical concepts in their structure and design, such as: (1) The Honai house adopts a cylindrical and conical shape for space efficiency and durability; (2) The Kaki Seribu house highlights symmetrical patterns in its numerous supporting pillars, reflecting adaptation to the surrounding environment; (3) The Rumah Pohon applies principles of proportion and stability to ensure safety from external threats; (4) The Rumsram house represents the Biak people's connection to maritime culture while demonstrating geometric principles in its trapezoidal and rectangular structures. In addition to mathematical aspects, traditional Papuan houses contain philosophical and historical values that strengthen local cultural identity. Further research will focus on developing and testing Papuan culture-based mathematics learning models. For example, creating didactic designs that use the Honai House concept to teach geometric shapes (cylinders and cones) or the Thousand-Legged House to teach symmetry and patterns. The effectiveness of these models in enhancing student understanding and interest could be the focus of testing. Practical applications include creating textbooks, modules, learning videos, or even interactive apps that showcase traditional Papuan houses as a medium for learning geometry, patterns, and measurement.

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.
