About 60 years ago, a Japanese mother accidentally discovered her son's "little secret" while washing clothes for her children. Her son, who is in the second grade of elementary school, hides a math test paper in his trouser pocket. When she opened it, she was very angry because she always thought her son was good at math, but she didn't expect him to do so badly in the exam. However, her mother is still very rational and did not participate in the "mixed doubles" for her son and father.

On the contrary, she sharply criticized her husband. Why? Because my husband is a high school math teacher, it is reasonable to say that my son should be outstanding in math, but it is really embarrassing to get into this now. Naturally, the first thing that comes to mind is her husband, so she blames him for not caring about his son's math study. Her husband has a good attitude and accepts criticism with an open mind. Since then, he has personally helped his son learn mathematics.

Father's name is "Official Document Gong". Because of his solid foundation in mathematics, after carefully studying his son's study, he decided to write his own study materials for his son. So, he began to sort out, classify and edit the mathematical knowledge he had to master in primary and secondary schools. After many attempts, he finally compiled a set of unique mathematics textbooks, because this is a "exclusive workbook" tailored to help his son learn mathematics well.

My father is also far-sighted. He not only wants to help his son improve his math scores, but also hopes that his son can improve his learning ability. Even if he enters high school, he can easily cope with exams and learn to study independently. He believes that "the biggest duty of educators is to cultivate children's attitude and habits of autonomous learning", which is what he attaches most importance to when compiling learning materials for his son. Then, the question is, how to cultivate children's autonomous learning ability?

It is generally acknowledged in official documents that if children want to learn to study independently, they must find ways to get "satisfaction" in their studies. As a high school math teacher, he knows very well that the most important reason why children can't get satisfaction from math is the "frustration" caused by insufficient computing ability. To this end, he made great efforts to cultivate his son's computing ability and compiled a set of mathematics textbooks to help his son "learn by himself".

He is convinced that once his son has enough basic computing ability, it will be more conducive to developing his comprehensive application ability and eventually help him master the essentials of mathematics well and quickly. That's true. From the second grade of primary school, my son began to learn step by step from the addition of two digits according to the special teaching materials compiled by his father, and taught himself for about 30 minutes every day. After four years of training, when he was promoted to the sixth grade of primary school, he was able to solve calculus problems in high school mathematics independently.

Neighbors' parents saw that the children of the official document family had made such great progress, so they asked the official document family to help the children. So, officials invited nearby children to their home and let them learn in the same way. After a period of time, these children's learning ability has been significantly improved.

From these children, Guan Gonggong realized that the key to such achievements lies in writing textbooks not from the standpoint of teachers, but from the standpoint of learners. It is not limited to the school year in which the child is located, but based on the actual ability of the child, starting from a simple place, ensuring that the child can learn easily, gradually improving the learning difficulty in small steps, and striving to learn the content of high school and even college steadily.

With such practical experience, the official decided to "use this learning method to develop more children's potential" and let them truly realize their potential and the fun of learning. So 1958 set up a company in Osaka, Japan, determined to open more official education centers. With the goal of "learning materials from self-study to senior high school", every child can improve his learning ability by independently learning content suitable for his own ability-the promotion of official document learning method began.

Now, the official document learning method has developed to Japan and many countries and regions in the world. As an educator and a father, Mr. Wen Gonggong's lifelong educational philosophy is "all children have unlimited potential", which makes this fatherly love become the love for all children in the world, and this love makes this educational method continue to this day. ...
