The progress and results of the Technical Cooperation Programme on nuclear science and technology education for the secondary schools in the Asia-Pacific region by the IAEA over five years from 2012 were introduced. Assembling laboratory instruments accompanying the observation of trajectories of radiation in the classroom, the history of the discovery of radiation and radioactivity timely described in the process, the mechanism and the concept of radiation measurement etc., which were explained and introduced by Team Japan, were all really effective. It is concluded that further development of these activities will become one of the cores of STEM education in Asian countries and play an important role in the expansion and deepening of NST education.
