Tahapan aktivitas pembelajaran yaitu 1) stimulus masalah terbuka, 2) penyusunan konjektur, 3) verifikasi konjektur dengan ART, dan 4) generalisasi. Kata kunci: Penalaran, ART, Segiempat, Konjektur. Abstract: Abstract Axiomatic deductive reasoning is the most widely used approach in proving geometric statements. Concepts of abstract thinking that are still immature lead to errors in proof. Current developing technologies provide a connection for us to visualize abstract concepts in geometry. Dynamic Geometry Software has the potential to be developed to assist the reasoning process. Automation can be explored in the integration of technology for reasoning processes. This study aims to design geometry learning activities by integrating GeoGebra's Automated Reasoning Tools (ART) on the topic of Quadrilaterals. This research is research and development by adopting the ADDIE model. The stages carried out in the research are the Analysis, Design, and Development. Literature Review was conducted to design geometry learning activities. The result of this study is the design of Geometry learning activities with ART. The learning activity approach uses the Discovery Learning. The result of learning activity development is there are four main stages of these activity. The designed learning activity, namely 1) open-ended problem stimulus, 2) constructing conjectures, 3) verifying conjectures with ART, and 4) generalizing. Keywords: Reasoning, ART, Quadrilateral, Conjectures.

This study mapped the contemporary research landscape surrounding “oral traditions as a fount of ethnomathematics knowledge” through a bibliometric analysis employed as a methodological procedure. The main problem addressed in this study is the lack of a comprehensive consideration of evolving research trends and intellectual structure within ethnomathematics, i.e., the role of oral traditions as a source of knowledge. Oral traditions, defined as the cultural knowledge, art, ideas, and practices transmitted verbally across generations, offer a rich repository of ethnomathematical insights. 713 publications were identified from the Dimensions database between 2014 and 2024. This bibliometric analysis focused on identifying key research themes, authors, publishers, keywords, or key terms distributions within the corpus of extracted publications, as well as temporal trends in publication activity and citation patterns. The findings revealed a growing interest in the field, focusing on (a) educational context, (b) cultural studies, and (c) the intersection of mathematics and language. The analysis also identified key research themes, such as (a) the role of language and culture in shaping mathematical thought, (b) the development of ethnomathematical practices, and (c) the pedagogical implications of incorporating ethnomathematics into formal education. Additionally, 11 influential scholars who are driving the field forward were identified. According to the term distribution analysis, of the 6,092 terms, 316 met the threshold (minimum number of occurrences of the term: 6). For each 316 terms, a relevance score has been calculated. Based on this score, the most relevant terms have been selected. The VOSviewer’s default setting (60% of the most relevant terms) resulted in selecting 190 terms. Based on the given criteria, there is a result of 5 distinctive clusters related to the query that emerged. This study provides theoretical insights into the conceptual foundations of ethnomathematics derived from oral traditions and empirical evidence for informing future research directions and pedagogical practices in mathematics education.

Integrating mathematics with other fields is necessary for students to tackle real-world problems. Incorporating technology and engineering, such as robotic activities, into science and mathematics teaching offers the potential to improve learning outcomes and enhance students’ 4C (Critical Thinking, Creativity, Collaboration, and Communication) skills. This study aims to design and develop a STEAM (Science, Technology, Engineering, Art, and Mathematics) teaching module supported by the robotics activity Drive Up a Slope for middle school students and evaluate its feasibility and practicality in enhancing students' 4C skills. The development process of the teaching module follows the ADDIE model (Analyze, Design, Develop, Implement, and Evaluate). The results of this development indicate that the quality of the teaching module is categorized as highly valid, with a validity percentage of 94.64%, and highly practical, with a practicality percentage of 90%. Therefore, it can be concluded that the developed teaching module is both valid and practical.
