Senior one students should know their learning changes in senior three in advance, make clear their learning priorities, adjust their learning methods, master efficient learning strategies, and do a good job in the transition from junior high school, especially in difficult subjects, so as to adapt to the learning rhythm of senior three as soon as possible after school starts.
The overall difficulty of high school mathematics will be improved.
As one of the three main courses, mathematics is a difficult and key subject in senior high school, and it is often a sub-item that can open a big gap in the exam. Before the college entrance examination reform, high school mathematics was divided into liberal arts mathematics and science mathematics, and the difficulty of liberal arts mathematics and science mathematics was different. However, the new college entrance examination cancels the division of arts and sciences, and the mathematics in the college entrance examination becomes a unified test paper, so the overall difficulty of mathematics learning will be improved.
The new version of high school mathematics textbooks has increased or decreased in content, paying more attention to the cultivation of mathematical core literacy and mathematical ability. The new curriculum standard divides senior high school mathematics knowledge into three parts: function, geometry and algebra, probability and statistics, and adds a mathematical application, namely mathematical modeling and inquiry.
At the same time, some contents have been deleted from the new high school mathematics textbook, but the deletion of contents does not mean that the difficulty of high school mathematics learning is reduced. For example, the content of calculus is removed from the new textbook, which narrows the learning range of derivatives, but it also leaves more time for the concentrated breakthrough of difficult knowledge of derivatives, reflecting the changing trend from more to more precise.
There is a big difference in mathematics between junior high school and senior high school.
There are great differences in knowledge difficulty and ability requirements between senior high school mathematics and junior high school mathematics. Some students with good academic performance in junior high school have obviously decreased their math scores after entering senior high school, which has hit their self-confidence in math learning and caused resistance to math learning in senior high school.
The emergence of this situation is related to the learning content of high school mathematics. The content of junior high school mathematics learning is relatively simple and specific, and there are few knowledge points involved. In senior high school, mathematics learning has become more abstract and complicated, and more knowledge points are needed, which makes the content more difficult on the one hand and accelerates the pace of learning on the other.
Mathematics language in senior high school has changed greatly in abstraction, and concepts such as set and function are difficult to understand. The abstraction of this mathematical language puts forward higher requirements for thinking ability and requires students' thinking methods to leap to the rational level.
? What preparations should be made to do a good job in junior high school mathematics convergence?
First of all, lay a good foundation and check for leaks.
There is a great difference between junior high school mathematics and senior high school mathematics, but it does not mean that they are not related. Knowledge learning is a gradual deepening process, and the learning level of the previous stage will have a certain impact on the subsequent learning.
The learning content of junior high school is the basis of mathematics learning in senior high school. For example, some operation formulas in junior high school mathematics will continue to be used in senior high school. High school solid geometry will also use the related content of plane geometry in junior high school. Therefore, in order to do a good job in the connection of junior high school mathematics, we must first lay a good foundation and check the key knowledge of junior high school.
Second, preview in advance to improve knowledge understanding.
Classroom is the main battlefield of knowledge learning. In order to improve the efficiency of classroom learning, we need to make preparations before class. Because the knowledge of high school mathematics is difficult and needs to be mastered, the teacher will speed up the lecture in class. In order to better keep up with the rhythm and ideas of teachers' lectures and improve the efficiency of lectures, students can preview before class.
Students can use the summer vacation to preview the learning content of senior one mathematics, especially for the important and difficult knowledge, reduce the learning burden and increase their self-confidence in learning senior one mathematics well.
Third, master methods to improve learning efficiency.
The change of high school mathematics learning content makes students need to change their specific learning methods accordingly. For example, in junior high school, after learning new knowledge in class, you can master relevant knowledge points through certain exercises after class. However, in senior high school mathematics, just brushing the questions may not really master the knowledge, but the effect of doing the questions is the key. Therefore, in the study of high school mathematics, we should pay attention to the idea of doing problems and know where to cut in when solving problems.
