Before the Ren Xu school system, China had promulgated the following school systems: 1902 Renyin school system, 1903 Guimao school system, 19 12 Renzi school system and19/3 Renzi school system. Because this kind of education system evolved from the late Qing Dynasty, and the education system in the late Qing Dynasty was almost completely copied from Japan, it could not meet the needs of social development in China at that time, especially the vigorous situation initiated by the New Culture Movement since 19 15. Therefore, the academic system of Ren Xu (1922) came into being under this historical background. The educational system takes seven standards as the guiding ideology of reform, namely: 1, to meet the needs of social evolution; 2. Give play to the spirit of civilian education; 3. Seek the development of personality; 4. Pay attention to the national economic strength; 5. Pay attention to life education; 6. Make education easy to popularize; 7. Leave more room for expansion in various places. It can be seen that these seven standards attach great importance to education for social development, and at the same time take into account people's personality development. However, it is particularly noteworthy that the first epidemic "leaves more room for expansion and contraction in various places". Ren Xu's education system is divided into three parts: primary education, secondary education and higher education. The stage of general education imitates the "633" system in the United States, that is, six years in primary school, three years in junior high school and three years in senior high school. However, according to China's national conditions, primary schools are divided into two stages: four years in primary schools and two years in high schools. In this regard, Tao Xingzhi explained: "The new six-year primary school is not easy to do in rural areas, but the four-year primary school is better." He said "four-year primary school" or "junior high school". Compared with the educational system of "abandoning children and removing ugliness" promulgated by 19 13, the new educational system has changed from 7 years of primary education (4 years of primary school and 3 years of high school) to 6 years, and the middle school has increased from the original 4 years to 6 years. Moreover, the high school implements the credit system and the subject selection system, which is divided into general, agricultural, industrial, commercial, normal, family and other subjects. It is also called comprehensive middle school, that is, vocational education is incorporated into general education, and it is stipulated that "a single subject or several subjects should be set up according to local conditions". In recent years, the author found that Huiwen was a famous school in Beijing Academy during the Republic of China. At that time, in addition to arts and sciences, there were actually business subjects (the late calligrapher and linguist Mr. Qi Gong was a dropout of Huiwen Business 1932) and education subjects. I didn't understand why until I saw the academic system in Ren Xu. Hu Shi, the director and drafter of the new school system, said in the article "Reflections on the New School System" in 1922: "The special advantage of the new school system lies in its flexibility." He also seems to say that this flexible system is very needed. Nowadays, the rigid primary school is really unfair to the gifted children and the well-educated children. I remember seventeen years ago, when I was in Shanghai Meixi School, I was promoted from No.12 Middle School to Grade Four. Later, in the city school, one year later, I was promoted to two levels. I lived in Shanghai for more than five years, changed to four schools, and ran away before graduation. The academic system there has not been formally implemented, so the upgrading and transfer in the school is extremely free and flexible. Looking back on that era now, I feel that in those five years, I have never suffered from the loss of transfer, nor have I been depressed by grading. Tao Xingzhi expounded the importance of "flexibility" from the perspective of rural education. In the article "New Trends in Normal Education" published by 192 1, he said that rural education is underdeveloped, which can be said to have reached the extreme. ..... This kind of inequality between urban and rural areas is unavoidable in all countries, but the rural areas in our country are also suffering too much. I am afraid it is not the blessing of the city people; As for teaching materials, rural areas and cities are also very different. For example, electric lights and oriental cars are common in cities, but it is difficult to teach these many textbooks in rural schools. There is also a holiday building. The countryside is different from the city. What silkworm leave, rice leave, where can we use regulations to bind him! More than 80 years have passed. Recently, the author read a teaching note by Zhang Ting, a reporter from Phoenix Weekly. It is mentioned in the article-for example, when talking about area in math textbooks, we often calculate how many tiles need to be laid on a wall or a floor, and what kind of tiles are cost-effective. Looking at the wooden walls and mud walls that are drafty everywhere, it is difficult for students to understand what ceramic tiles are for. If you encounter the problem of filling in the correct length unit for a swimming pool, you can basically only guess. They all bathe in the river, so how big the swimming pool should be. ..... This kind of example is endless, and it is also common in Chinese and science textbooks.
