First,? Middle school mathematics and junior high school mathematics are more difficult. It is difficult for children to adapt to the special difficulties found by many people in mathematics after entering high school. They can understand teaching, but they can't do it when they start working. Even if the work is finished, there are many inaccuracies. Middle school mathematics itself is very different from junior high school mathematics. Junior high school mathematics is presented in simple words, with a unified way of thinking. For example, expression can be completed in two steps, with a set of ideas and tricks. After high school, math classes become more and more abstract, which tests students' logicality. When children's thinking gradient direction is not up to standard, they will feel unable to understand function formulas and patterns in math class. More and more abstract concepts in math class have higher requirements for students' logical thinking ability, and once this requirement is not met, students will find it particularly difficult to learn and feel mysterious.
Second, after students enter high school, the polarization is very serious. Some students are not polarized in junior high school, but they are polarized after senior high school, and this phenomenon is very serious. There are many reasons for polarization, such as not liking this course, for example, teachers' evaluation will also lead to polarization, and some people who study science hard will also lead to polarization. And many people are polarized, when they are polarized, it will do great harm to their comprehensive performance. We must not be emotional about the course, and we must be clear about our personal goals, mainly to make up for the insufficient courses. If the polarization is too serious, we should get the best results in the subjects we are good at and improve our comprehensive results. If we want to avoid the polarization of mathematics, we should find the fun of mathematics, instead of contradicting or even giving up mathematics classes.
Third, the learning and training methods are wrong, and there is a certain pressure on ideas. Mathematics in middle school will naturally be much more difficult than that in junior high school, and the specific content is not much, and the progress is relatively fast. In addition, the amount of data in each subject is very large. If you can't effectively consolidate your review, you will soon forget it. Because if you want to improve your math scores, you must master the methods, don't have to memorize them, learn to grasp the key points, analyze the key content problems, and analyze the types of questions, instead of coping with the past, and there is a reflective imitation of formula calculation. This result is only a little knowledge and no progress. After entering high school, many people feel that there are still three years before the college entrance examination, so they relax their ideas, especially those students who rely on make-up exams in grade three, who will find it very difficult to study in high school. Senior one didn't lay a good foundation. Making up lessons in senior three will eventually live up to our hopes. It must be remembered that the difficulty of junior high school mathematics can not be summarized in junior high school mathematics class, and it takes three years of hard work in senior high school to be less flustered in the college entrance examination.
