Background 〜For teachers and parents〜

The final goal of this project organizer is,,,

・Contribute for “Creation of peaceful and sustainable society” through “Mathematics education to live in society”
・”SDGs from Mathematics” : Develop human capital who can grasp society with mathematics, engage in it, solve issues, and create values.

More specifically,,,

・Increase students’ motivation to learn by providing opportunity which enable young people to understand that mathematics can help solve social issues and create values, and to know different ways of thinking.
・Increase access to information for young people, promote employment, contribute to enrich-ing individual lives, and deepen cross-cultural communication by learning and understand-ing “mathematics, which is a universal language,”

Basic concept of mathematics education based on this project

・Improving mathematics skills does not only means improving mathematical abilities, but al-so developing mathematical literacy (ability to find and understand roles of mathematics in society and, to make judgement based on mathematical principles and to engaged in mathematics, in private life,
professional life, social life with friends, family members and relatives, and life as
constructive, highly-conscious and thoughtful citizen at present, past and future)
・In order to deeply learn mathematics, it is necessary to recognize that mathematics is relat-ed to an individual’s interests and future dreams, and that mathematics is necessary to un-derstand the world.

Further plans from next year

・Japanese education experts analyze the submitted works and based on the results, formu-late a training program for mathematics education for teachers
・Organize the training program and seminar if possible
・International exchange of young people through their works
