Abstract This study aims to integrate the Research-Based Learning (RBL) model with the STEM approach and graph theory in solving transportation and logistics optimization problems to enhance students’ computational thinking skills. The model is designed to train students in identifying transportation and logistics issues, exploring solutions based on graph theory, and analyzing and optimizing distribution routes using algorithms such as Dijkstra and Floyd-Warshall. This research employs a narrative qualitative method, analyzing research-based learning through six RBL-STEM phases: problem identification, initial solution exploration, data collection, data analysis, result interpretation, and model presentation. The results show that this approach significantly improves students’ skills in problem decomposition, pattern recognition, algorithmic thinking, and abstraction in solving real-world problems. Concretely, students demonstrated an average score improvement of 23% in computational thinking indicators after participating in the learning process, particularly in designing optimal route graph models and constructing algorithmic logic for route selection. Moreover, the use of technologies such as Google Maps and graph modeling software enables students to perform real-time data-driven analysis. Therefore, this study proves that the integration of RBL-STEM and graph theory not only enhances conceptual understanding of transportation and logistics optimization but also equips students with applicable computational thinking skills for real-world contexts. This learning model can serve as a reference in developing more innovative and industry-relevant STEM-based teaching strategies.

Abstract Written mathematical communication is important in learning mathematics because it helps students convey ideas systematically and revise solutions more easily. In problem solving, mathematical communication serves to understand, design, and communicate strategies in writing. One of the factors that influences mathematical communication is gender, which shapes students' thinking, communication patterns, and problem-solving strategies. This study aims to describe junior high school students' mathematical communication in solving Pythagorean Theorem problems in terms of gender. This study used a qualitative descriptive design, involving two students who were purposively selected and identified through the Bem Sex Role Inventory as students with dominant feminine or masculine characteristics. The results show that both students demonstrated mathematical communication in understanding the problem, planning the solution, and implementing the solution. (1) The male student illustrated and wrote down accurate but incomplete information. He planned the solution by illustrating and writing down the steps and formulas accurately and fluently but incompletely. Illustrations, calculation processes, and conclusions were expressed accurately and fluently, but were incomplete. (2) The female student wrote down information and a solution plan accurately and fluently, but they were incomplete. She expressed the calculation process accurately and fluently, but it was incomplete; while the conclusion was accurate, complete, and fluent. Keywords: gender; student mathematical communication; problems; pythagorean theorem Abstrak Komunikasi matematis tulisan penting dalam pembelajaran matematika karena membantu siswa menyampaikan ide secara sistematis dan merevisi solusi dengan lebih mudah.
