The purpose of this research was to investigate the growth of high school students and their teacher through their experience of a special science learning abroad programme. Two high school students and one high school science teacher visited the UK for nine days to participate in the programme. The contents of the programme included ‘Visit of Advanced Science Research Institutes’, ‘Participation in Science Festival for the Public’, ‘Visit of a high school’, and ‘Visit of a science museum’. During the stay, we distributed a daily report to the participating students and high school teacher and analysed the collected data. As a result, both participating students and their teacher developed positive opinions on the willingness to learn foreign languages, the importance of international exchange, the spread of their vision towards science and researchers, and the motivation for science learning, and raised their self-affirmation as well. In particular, it was suggested that the impact of the international programme had a greater positive influence on teachers than on students. It is important to show the possibility that such overseas educational programmes would have a positive influence on the supervisory teacher and not just on the participating students.
