2. Analyze the example from another angle.

3. Analyze examples and sum up experience.

1, the mutation of mathematical language. Freshmen react to old fun. When learning high school knowledge in advance in summer vacation, the concepts of non-assembly and mapping are difficult to understand and feel far away from life. Indeed, there are significant differences in mathematics language between junior high school and senior high school. Junior high school mathematics is mainly expressed in vivid and popular language. High school mathematics involves abstract set language, logical operation language and functional language, space solid geometry and so on. ?

2. A leap in thinking methods. Another reason why senior one students have obstacles in mathematics learning is that the thinking method of mathematics in senior high school is very different from that in junior high school. Great changes have taken place in the thinking form of senior high school mathematics. As mentioned in the last section, the abstraction of mathematical language puts forward higher requirements for thinking ability. Of course, the cultivation of ability is gradual, not overnight. This sudden change in ability requirements has made many freshmen feel uncomfortable, leading to a decline in their grades. ?

3. The sharp increase of knowledge content. Another obvious difference between high school mathematics and junior high school mathematics is the sharp increase in knowledge content. Compared with junior high school mathematics, the amount of knowledge and information received per unit time has increased a lot, and the class hours for assisting exercises and digestion have decreased accordingly. In addition, senior one should study nine subjects at the same time. Assuming that each subject is assigned a little homework, it will take quite a while to add up, which virtually deprives me of my study time.
