Denpasar, August 22, 2025 – The journey of strengthening numeracy and literacy through Lesson Study reached its culminating moment in Bali, where teachers, education personnel, and young learners gathered for the final series of this inspiring program. Organized by SEAMEO QITEP in Mathematics (SEAQiM) in collaboration with CRICED University of Tsukuba, SEAMEO QITEP in Language (SEAQiL), and Balai Guru dan Tenaga Kependidikan (BGTK) Bali, this event marked both a celebration and a reflection of shared commitment to advancing mathematics education in Indonesia and the region.
The Lesson Study series has travelled across three cities: Jakarta, Yogyakarta, and finally Denpasar, bringing together Japanese elementary school teachers, Indonesian educators, and education stakeholders to explore how mathematics can be taught in meaningful and transformative ways. Using the Japanese reference book Belajar Bersama Temanmu as the backbone of the lessons, participants experienced first-hand how mathematics is not only about numbers, but also about reasoning, communication, and character-building.
The day began with an opening ceremony filled with warmth and optimism. It featured remarks from the Director of SEAQiM, representatives from CRICED, and the Head of BGTK Bali. The spirit of collaboration resonated strongly, highlighting the international partnership that made this initiative possible.
Like the two series before, the heart of the program unfolded through two live classroom sessions conducted by Japanese teachers, focusing on Fractions and Number Composition & Decomposition. Local students from SD 2 Sesetan, Denpasar, participated with remarkable enthusiasm, while more than a hundred observers, including teachers, school principals, supervisors, and education specialists, watched closely, taking notes and reflecting on the methods.
Prof. Masami Isoda, a figure in mathematics education from the University of Tsukuba, added depth and wisdom to the program. More than just a guest speaker, Prof. Isoda guided participants in seeing mathematics beyond numbers. In his How to Develop Mathematical Thinking session, he emphasized that mathematics should not be confined to procedures but must serve as a language of reasoning, creativity, and humanity. His insights drew the attention of all present, highlighting how textbooks like Belajar Bersama Temanmu are not merely tools, but bridges connecting classroom instruction with critical thinking. Exhibitions from Seibun-Sya and ArTec added further richness, showcasing innovative resources in mathematics and STEM education.
As the event concluded with heartfelt appreciation from SEAQiM and CRICED, participants left with more than just new insights. They carried a renewed vision: to force numerically literate students, critical thinkers, problem-solvers, and empathetic individuals, prepared for the challenges of the digital age.
The Bali series was not just the end of a program. It was the beginning of a stronger movement in education.
