This project between the EU and Brazil aims to enrich student learning through open schooling and participatory science in the core curriculum. Open schooling promotes cooperation between schools, scientists, and local communities for students to solve real problems. The Augmented Reality in Schools initiative involved science teachers, students, researchers, and medical students using AR to guide secondary students in science subjects supported by scientists. Participants engaged with real-life issues, used AR to acquire knowledge supported by teachers, and worked with peers on participatory science projects related to COVID-19. Findings showed AR helped students explore concepts visually and interactively, engaged them in discussions with researchers, and increased their interest and understanding of science. Recommendations included planning, access to resources
