As a teacher who has been working on textbooks recently, I bought all the nine editions of textbooks on the market. I want to say that the Soviet version of yyds really pays attention to the cultivation of higher-order thinking. People's education edition is what I am using, and it is very solid. But if children want to achieve high academic performance, the Jiangsu and Zhejiang version is really a masterpiece.

The version of mathematics has nothing to do with improving students' learning ability, and the difference of its own version is due to the different settings in different regions. Each provincial publishing house has a textbook version with local characteristics, which meets the teaching objectives of local school teachers and has nothing to do with which version improves students' learning ability.
