The three bases approved by Beijing Normal University this time are: the research base of mathematics textbooks for primary and secondary schools, the research base of chemistry textbooks for primary and secondary schools, and the comprehensive research base of basic education textbooks. From the names of these three bases, we can see that Beijing Normal University's research on Chinese textbooks covers all levels, especially in the field of mathematics, which is why Beijing Normal University's mathematics is highly valued by the outside world.

In addition to Beijing Normal University, there are two bases approved by Beijing University, namely, the research base of political science textbooks in colleges and universities and the research base of literature textbooks in colleges and universities.

The approval of these two bases can also show the position of Peking University in these two disciplines. As a top university in China, Peking University has super strength in the fields of scientific theory research and humanities and social sciences. From the names of these two educational bases approved by Peking University, it can be seen that Peking University has little research on basic education in China.

In addition to these two top universities, other universities have obtained bases, among which Beijing Foreign Studies University and Shanghai International Studies University have obtained research bases for foreign language teaching materials in primary and secondary schools. Although the name of the base approved by the two universities is the same, the language may be different, and even the two bases may have a certain degree of cooperation.

These two universities are the best language universities in China, and few universities can compete with them in the field of foreign language education.

As one of the best music universities in China, Shanghai Conservatory of Music is also a double-class university. The base approved by the school is called the research base of art teaching materials in primary and secondary schools, and this educational base of the school is generally called the research base of art teaching materials. However, judging from the discipline layout of this university, the art textbooks of this university should focus on studying music textbooks, and they are aimed at music textbooks of primary and secondary schools.

East China Normal University, another 985 normal university in China, was approved as a research base for geography textbooks in primary and secondary schools. This university itself is very strong, and it is the leader of the national normal university in some disciplines. In addition, with the good development in recent years, it has made progress in many disciplines. This time, it was approved as the research base of geography textbooks for primary and secondary schools, and it can also be seen that this school is an advantageous discipline in the field of normal education.
