The Royal Grace Towards Mahidol Wittayanusorn School
As the first model science school in Thailand, it carries the mission of providing education for students with exceptional abilities in mathematics and science. The goal is to develop their potential to the fullest, enabling them to become key contributors to the nation’s future development.
“The Path of Wisdom from Visionary Insights” in Science and Technology Education
Her Royal Highness serves as the President of the POSN Foundation, which focuses on nurturing high school students across the nation with exceptional abilities in science and mathematics.
The foundation provides opportunities for students to develop their potential in both theoretical knowledge and practical skills. It equips them to analyze and synthesize complex problems effectively, preparing them to compete in international academic Olympiads.
Her Royal Highness supports the Science Society of Thailand, which was established with the objective of advancing scientific activities and fostering knowledge exchange among its members, promoting unity and collaboration among the scientific community while giving scientific knowledge to the general public.
Her Royal Highness initiated and envisioned the collaboration between Thailand and CERN, the leading global organization in high-energy particle physics research. She remarked that:
“If Thai scientists have the opportunity to work with CERN, it will significantly benefit the advancement of science and technology in Thailand.”
This collaboration was established to enable Thai physicists to participate in particle physics research. Furthermore, students and physics teachers were selected to attend summer camps at CERN, located in Switzerland.
In the first year of this collaboration, teachers and students from Mahidol Wittayanusorn School were graciously granted the opportunity to participate under Her Royal Highness’s patronage.
Her Royal Highness initiated efforts to enable Thai university students, researchers, and scientists to participate in the prestigious Nobel Laureate Meetings in Lindau.
This initiative provides Thai participants with an invaluable opportunity to broaden their academic horizons, learn about cutting-edge scientific advancements, and gain insights from the experiences of Nobel laureates.
Furthermore, Her Royal Highness has fostered collaborations with leading global scientific organizations and research institutes. These partnerships aim to provide Thai students, researchers, and scientists with opportunities to engage in knowledge exchange and collaborative research, thereby advancing the nation’s human resource development in science and technology. Through these initiatives, young scientists have participated in royal-sponsored programs such as DESY, GSI, IceCube and ITER
Her Royal Highness has instituted awards and accolades to recognize teachers who have made significant contributions to education in Thailand and the Southeast Asian region. Through the Princess Maha Chakri Award Foundation, outstanding teachers are celebrated for their dedication and impact. Moreover, the teachers were provided with opportunities to share their practices, perspectives, and knowledge, fostering professional growth and promoting the exchange of ideas, enriching the teaching profession.

INTERNATIONAL SCIENCE SCHOOLS NETWORK
The International Students Science Fair (ISSF) is an annual event co-ordinated by a global collective of specialist science secondary schools who have agreed to collaborate for the benefit of their own students, as well as promoting the importance of science and STEM (Science, Technology, Engineering and Mathematics) education in their own countries and internationally. The schools recognise that high quality education and innovation in STEM hold an important key to the successful and sustainable future of our countries and our planet, and that international collaboration will provide a platform which will enable all of our students to work towards this goal.
The ISSF has run successfully since 2005, and is the major event of its type in the world. It brings together students, teachers, schools and university leaders to share and develop their ideas about science in the modern world. Students and teachers from around 35 specialist science schools attend, by invitation, a five-day learning programme organised by an elected host school.
The schools who have collaborated since 2005 to provide this outstanding opportunity for their schools and students have joined in support of excellence in science education on a global scale.
The schools previously involved in the ISSF intend to establish an identity as a collaborative and influential body of schools that speaks clearly to a wide range of audiences about the nature, purpose and significance of the network and its capacity to be a forum in promoting leading edge Science education on a global scale. We define ‘Science’ broadly to include STEM.
The name of this network is proposed to be the International Science Schools Network (ISSN), whose logo appears at the top of this document.
The ISSN decided that it needed to operate under a set of clearly articulated and agreed procedures, and this document was constructed in response to that requirement. It has undergone several revisions since the first draft appeared at the conclusion of the 2013 ISSF event, hosted by Camborne Science and International Academy in Cornwall, UK It is regularly updated by the Executive Steering Group at its annual meeting.

The International Students Science Fair
The International Students Science Fair (ISSF) is the major annual event promoted by the ISSN. The ISSF provides a unique forum for budding scientists to display their enquiry skills and defend their findings in a non-competitive environment. The event provides senior (Years 10-12) students from around the world valuable opportunities to work in collaborative settings to exchange ideas, hone their research techniques and engage their inquisitive minds in the fields of, science, technologies, engineering and mathematics (STEM), with like-minded peers.
Opportunities are provided that extend student thinking, allowing them to use their knowledge in interesting ways and encourage all participants to explore their ethics and assumptions in the STEM fields. In particular, the team-work in problem solving and sharing sessions gives students and educators the opportunity to work with peers from different nations, thus promoting the inter-cultural understandings needed in the 21st Century. A significant component of ISSF is the cultural and social interactions which help develop friendships and collaborative opportunities amongst our students and educational leaders which may be the basis for future cooperation and study.
Important Features of the ISSF
The major focus of the ISSF is sharing and collaboration. The event itself is not competitive, but a chance for students to share knowledge and ideas, and to gain constructive feedback on their work from academic experts and teachers. Schools may acknowledge excellent posters or presentations in any suitable way, other than by making awards in order of merit.
