The so-called watershed of the first two years is just on the basis of the first year of junior high school, the excellent are more excellent, and the ones who can't do it really can't do it. Even if the difficulty of mathematics and English has increased, it does not make this learning stage a watershed, and learning ability is not the core factor in the stratification of grades at this stage, but learning attitude is.
1. The weight of the grades in the whole junior high school stage is obvious, and the gap between the advantages and disadvantages of scientific thinking is not obvious.
Of the nine cultural courses in junior high school, only one mathematics and half of physics really have the characteristics of science, English is certainly a competition for memory, political history is also a competition for memory, and even chemistry and physics are also a competition for memory.
In the case of physics is relatively simple, the distinction of mathematics alone cannot completely stratify students.
2. The intensity and pressure of in-school learning in junior high school are not large, and the difference in off-campus learning intensity makes the performance not equal to the actual ability of students.
Even students who are not good at science thinking do not necessarily have bad grades in mathematics, first, there is only this subject that relies on thinking, second, students have sufficient extracurricular time, and third, although junior high school mathematics is difficult, the change of question types is limited.
This makes it possible for children who are not particularly dull to use their extracurricular time to rely on model training from training institutions to achieve higher grades. There are not many chicken babies in the second year of junior high school, but they are definitely the weakest type of thinking ability.
The first stage of high school is the time when the top students and pseudo school bully see the high and low, and those elements of junior high school that can make up for the clumsiness, one is that all subjects are difficult, especially the difficulty of physical chemistry is no less than mathematics, it is difficult to concentrate on one subject, and the second is that the study time in school is extended, there are few weekend holidays, and there is not much time for extracurricular training in the evening, even if there is time, it is difficult to balance the time in various disciplines, and it is difficult to improve the model training in junior high school.
Therefore, the essence of the reshuffle of the first year of high school is not only the greater difficulty, but the difficulty and the extension of the learning time, which makes the disadvantage of the lack of ability of the pseudo-academic bully who can make up for the clumsiness.
