Mathematics curriculum standard emphasizes: pay attention to the cultivation of students' various abilities, including mathematics reading ability and examination ability. However, in the actual mathematics teaching, I often find that some students "understand as soon as they listen, make mistakes as soon as they do, and have a little knowledge." Why is this happening? A basic idea in the mathematics curriculum standard is that students are the masters of mathematics learning, and teachers are the organizers, guides and collaborators of mathematics learning. As front-line educators, we have the obligation to think about this problem, investigate the problems existing in students' examination and reading, and help students find strategies to solve them. Attention should be paid to the cultivation of students' reading and examination ability.

Examining questions is the beginning and key to solving problems. Students' ability to examine questions will directly affect the result of solving problems. Therefore, in the teaching process, mathematics teachers should pay attention to analyzing the reasons of students' obstacles in examining questions, looking for countermeasures and cultivating students' ability in examining questions.

First, the meaning of the ability to examine questions

The ability to examine questions is a comprehensive ability, including reading, understanding, analysis and synthesis, as well as non-intellectual factors such as serious, earnest and meticulous attitude. Mathematics subject examination is a thinking activity of reading and understanding the mathematical knowledge involved in the topic, clarifying the conditions and requirements given by the topic, and trying to find out the relationship between the conditions and conclusions.

Second, the reasons for weak ability to examine questions

In many cases, all kinds of mistakes made by students in the process of solving problems are produced in the initial stage of examination. So why are students' ability to examine questions poor? Let me analyze it, which is often caused by the following reasons.
