The concept of function in mathematics is more abstract, although it continues the knowledge of quadratic functions in junior high school, but it is a re-examination of true and false students, and the same excellent mathematics results in the high school entrance examination rely on the application of typical example problems, or really understand the logical chain behind functional thinking.
Although compared with other science subjects, mathematics junior high school has increased in difficulty, from 1 to 2 is easier to go from 0 to 2, without obvious steep slope effect, but if you do not use junior high school learning to improve the corresponding thinking ability, just to improve the score and focus on skill training, there will also be a sudden decline in performance.
Compared with mathematics, the difficulty of physical chemistry from junior high school to high school is increased from 0 to 2, from almost no difficulty, but the difficulty of these two subjects guides students to choose subjects, and discourages students who have insufficient scientific thinking to choose liberal arts, and the track conversion is more obvious than mathematics.
The difficulty of mechanics in the whole junior high school stage is too obvious, especially force and motion, ignoring one of the most core knowledge points, that is, the calculation of object motion, if the difficulty of calculating the comprehensive question of uniform variable speed motion in high school is 2, the difficulty of average speed movement in junior high school is 1, without this 1, the learning difficulty reduced in junior high school is the difficulty of high school improvement.
Chemistry is not only difficult from 0 to 2, but also there are obvious differences in problem-solving thinking, junior high school chemistry focuses on the concept of memorization, and a large number of experimental essay questions, the assessment is often rote memorization, relying on thinking ability to understand and then analyze and elaborate intelligent students, but compared with hard memorization students, it is easier to lose points, making the results of chemistry distorted, which is more obvious than mathematics and physics.
While some students find high school chemistry more difficult, others are more adapted to the learning style of high school competition for logical reasoning ability.
