From the Large Hadron Collider to the Classroom: Inspiring Students Through the CERN HST2025 Programme

The International High School Teacher Programme (HST2025) at CERN provided educators with a unique opportunity to engage directly with frontier research in particle physics. More than a professional enrichment activity, the experience offers significant pedagogical benefits for students, enabling teachers to translate complex topics into engaging, accurate and accessible learning experiences. This paper reflects on how participation in the programme enhances classroom practice, connects high school physics to real-world research and inspires students to view themselves as part of the global scientific community.
