In the process of learning, I am not proficient in memorizing mathematical definitions and formulas, and I have not mastered the basic steps and methods of solving problems. This kind of students think that they have almost done all these things when reading books, but when they meet the exam, they find that they still have a lot of knowledge to master, and they often have trouble doing ambiguous questions.
Second, because of poor learning methods, I didn't master the methods of learning mathematics.
While studying, I temporarily remembered 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 all the contents memorized in a short time have been forgotten, 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, and the numerical and logical thinking of mathematics is relatively weak. This kind of students will not 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 in primary and secondary schools are not only set for gifted students, so as long as effective methods are adopted, 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' basic knowledge and understanding reach the standard, it is not difficult to get satisfactory scores. After targeted training, this ability will gradually improve.
