I think it is irresponsible to make mistakes in teaching materials. On the one hand, we can see that people do not pay enough attention to the publication of teaching materials. On the other hand, we can clearly see that in the process of checking textbooks, many people did not do their jobs well and did not take their work seriously. At the same time, we can also see that the supervision of the whole process is not enough. After many inspections, the wrong teaching materials are still circulating in the market, which will eventually cause some unnecessary losses in the market now, which is also an educational problem for us.

Shanghai fifth-grade pupils pointed out mistakes in math textbooks. As you can imagine, this is a serious mistake. Even fifth-grade pupils can find problems in textbooks, so our staff didn't find them in the process of cooperation. As you can imagine, this has nothing to do with the Lunar New Year, and they are not serious about their work at all, so I think this is an attitude problem. Such a problem in society will make us feel that it is a problem of level. As a student, I took the wrong textbook, but I didn't feel it. I'm valued, and I don't feel it. How serious this textbook is, I don't feel the authority of the textbook.

The emergence of such problems will make many students feel that the teaching materials are incorrect, so I think the problem of wrong teaching materials is a manifestation of irresponsible education and one of the manifestations of insufficient supervision by various regulatory authorities. There must be something wrong with a link that will lead to such a result.

In fact, I have always been critical of the mistakes in textbooks, because textbooks are a serious matter, which will affect many students and treat education issues extensively, so we should play a serious role.
