Between February and June 2026, students from Secondary School No. 25 Galați, coordinated by mathematics teacher Mrs. Violeta Bulai, participated in the international eTwinning project “Eco-Geometry: Exploring School Spaces Together”, together with partner schools from Turkey and Lebanon. The project brought together students aged 13–16 and created an interdisciplinary learning experience that combined mathematics, environmental education, sustainability, digital competences, and international collaboration.
The main aim of the project was to help students understand how geometry can be applied in authentic, real-life contexts while encouraging them to analyze and improve their school environment from a sustainable perspective. Throughout the activities, students discovered that mathematics is not limited to formulas and theoretical exercises, but can become a practical tool for understanding, measuring, and redesigning the spaces they use every day.
During the project, students explored different areas of the school and applied core geometric concepts by identifying and measuring triangles, quadrilaterals, diagonals, angles, perimeters, and areas found in classrooms, hallways, courtyards, ramps, windows, green spaces, and decorative elements. They used measuring tools and digital applications to collect accurate data and applied Pythagoras’ Theorem to solve practical problems, such as calculating distances, heights, and accessibility dimensions.
An important component of the project focused on scientific investigation and sustainability. Students measured environmental factors such as light intensity, temperature, sound levels, and space usage in order to better understand how geometry and environmental conditions influence comfort and efficiency within the school environment. By analyzing the collected data, they identified several issues related to lighting, unused spaces, accessibility, and environmental comfort.
The project also promoted digital learning and international teamwork. Students collaborated in mixed international teams using ICT tools, shared documents, online meetings, digital modelling platforms, and collaborative presentations. They created posters, models, infographics, presentations, measurement reports, and digital collages that reflected both the mathematical and environmental aspects of the project. Through constant communication and teamwork, students improved their digital, linguistic, and collaborative competences while learning to provide constructive feedback and exchange ideas with peers from other countries.
One of the most valuable outcomes of the project was the creation of the “Eco-Geometry Atlas”, a collaborative digital collection published on the project TwinSpace. The atlas includes measurements, geometric analyses, environmental observations, redesign proposals, photographs, models, and examples of good practices from all participating schools. This digital resource demonstrates how mathematical literacy can support environmental awareness and sustainable thinking.
Throughout the activities, students proposed creative and sustainable solutions for improving school spaces. Their ideas included better use of natural light, the creation of greener learning environments, redesigning areas to improve accessibility and comfort, and making school spaces more efficient and environmentally friendly. These proposals showed that students are capable of analyzing real problems and designing meaningful solutions using mathematical reasoning and ecological thinking.
The project had a significant educational impact on all participants. Students developed mathematical, scientific, digital, communication, and teamwork skills through practical learning experiences. They became more aware of the importance of sustainability and understood how mathematics can contribute to solving real-world challenges. At the same time, the project encouraged creativity, critical thinking, active participation, and intercultural dialogue.
The dissemination of the project was carried out through school exhibitions, presentations, posters, collaborative digital materials, TwinSpace activities, and community sharing events. Teachers, students, parents, and school representatives had the opportunity to discover the project results and observe how geometry can be connected to sustainability and everyday life.
“Eco-Geometry: Exploring School Spaces Together” demonstrates that modern education is built through interdisciplinary approaches, international cooperation, and applied learning. The project proved that mathematics can become an essential instrument for understanding the world around us and for building greener, smarter, and more sustainable school environments for future generations.
Together, we discover the geometry around us and create better school spaces for the future!
