Physics teachers from across Wales are attending a continuing professional development (CPD) course at the European Organisation for Nuclear Research (CERN) near Geneva.
They are studying a bespoke course introducing them to particle physics, featuring lectures, on-site visits, exhibitions and hands-on workshops.
When they return to Wales, they will be able to pass on their knowledge of the subject to the next generation of physicists, engineers and IT specialists.
Funding is to be provided from the National Science Learning Centre to help implement the action plans that the teachers will develop while at CERN.
Scientists at the Swiss facility use cutting-edge technology to collide particles at close to the speed of light, enabling them to gain insights into the fundamental constituents of matter.
Education minister Huw Lewis said the teachers' experiences would enable them to develop "innovative teaching practices when they return to the classroom".
"I'm sure that their pupils will be equally inspired," he added.
