In the process of learning, students are not skilled in memorizing mathematical definitions and formulas, and have a poor grasp of basic problem-solving steps and methods. This kind of students think that they have almost all these when reading books, but when they meet the exam, they find that there is still a lot of knowledge that they have not fully mastered, and they often encounter ambiguity when doing problems.

Second, because the learning method is not good, I have not mastered the method of learning mathematics.

While studying, I temporarily memorized the concepts, formulas and basic problem-solving methods of relevant knowledge, but they were not applied in time and the problem-solving methods were not consolidated in time. After a long time, you will find that you have forgotten what you remembered by short-term memory, or you will not do it if the basic questions change slightly.

The third type: because of the lack of logical thinking ability and habits of mathematics.

Everyone has different thinking ability and different thinking habits. Some students are more inclined to image and perceptual thinking, but relatively weak in mathematical and logical thinking. This kind of students won't have much problem with the basic knowledge and understanding of mathematics, but they may find it difficult to deal with some relatively difficult problems.

To sum up, the first two situations can actually be improved through effective education. The current teaching requirements for primary and secondary schools are not only set for gifted students, so as long as effective measures are taken, most students can meet the standards. The third situation varies from person to person and it is difficult to improve in a short time. At present, the questions used to examine students' outstanding ability in the exam are generally controlled within 20%. If students reach the standard in basic knowledge and understanding, it is not difficult to get satisfactory scores.

In view of the above problems, the concrete solutions are given.

For students with poor and weak mathematical foundation of the first kind, it is forbidden to make up lessons or do problems blindly. It is suggested that students and parents can choose their own study rules. Nowadays, many students are very smart and accept new knowledge quickly, so they will feel good at a glance. But if they don't practice, there will probably be loopholes in future exams. For learning, sometimes you can't fully master it simply by reading books. You must really master it through practical work. Give them 20 yuan a week.

For students who are not good at the second learning method, you can do some exercises. Because most questions will be analyzed by teachers, you can ask teachers or classmates for slightly more difficult questions. If you don't know or have some knowledge problems when you do it, explain it immediately, which is very helpful for understanding and deepening knowledge.
