1. Polarization means that in learning, students with excellent grades will get good grades and those with poor grades will be very poor, and there is an obvious gap between them.
2. The reasons are as follows:
Most of what I taught in the first grade is basic knowledge, which is easy to understand, and everyone's grades may be good; In the second day of junior high school, the difficulty will initially appear. For example, the geometry of mathematics will begin to appear, the first function, the grammar of English will begin to increase, and the classical Chinese will begin to become difficult. The knowledge of the second grade will be much higher than that of the primary school. Some people may have this problem because their foundation is not solid enough, or they don't listen carefully in class and review carefully after class.
The second day of junior high school is a very important year, which determines whether you can continue your study in the third day. Generally speaking, the grade of grade two is probably the same, or it may be worse. Of course, it is not difficult to overcome this difficulty. As long as you can preview before class, listen to lectures in class and review after class, there will probably be no problem. Mathematics is a headache for many people. In fact, as long as you do more math problems, not only the homework assigned by the teacher, you'd better buy a workbook to consolidate your exercises. And you must read and recite more English. Even if you don't want to listen in class, you must underline key phrases, sentences, grammar points and words. The language is similar. Reading and reciting are the most important, and classical Chinese is very important. There are also compositions, you can read novels, choose excellent compositions, and add a new subject physics. It's easier at this time, but you must listen carefully. Otherwise, senior three review will be very troublesome.
Polarization is nothing to be afraid of. The best way to avoid polarization is to study hard and keep working hard.
