"One subject, three transformations" refers to the educational concept of "taking the school as the main body, taking the curriculum as the core, taking education as the change and taking teaching as the center". This educational idea aims to build a modern educational system that meets the educational needs of the new era through the reform of schools, courses, education and teaching.

First of all, take the school as the main body. This means that schools play a central role in the education system. Only by taking schools as the main body can the overall stability and adaptability of the education system be guaranteed. As an important place to transfer knowledge, shape personality and improve literacy, schools should become the key node of educational reform.

Secondly, take the curriculum as the core. Taking curriculum as the core means taking curriculum content and teaching methods as the breakthrough to promote the development direction of new education reform. This teaching method can better meet the needs of students, and let students enjoy the fun of learning in the process of exploring knowledge.

Take education as the change and teaching as the center. The purpose of education is not only to impart knowledge, but also to cultivate students' comprehensive quality. Only in this way can we better meet the needs of social development. Therefore, we must regard teaching as the core of education reform, promote teaching reform, and build an education system that adapts to the new era, so that every student can study happily and meet future challenges.
