After entering high school, the content has increased a lot at once, and there are many knowledge points to understand and digest in each class, which makes it difficult to learn. It is difficult for many students to adapt quickly to the transition from junior high school to senior high school. In view of the above problems, Miao Jinli, a lecturer and senior math teacher of Beijing No.4 Middle School, said that high school students should learn "inquiry" learning of math knowledge.

First, computing power.

There are many contents involved in high school, and calculation is the basic skill. If there are still some problems in the operation of rational numbers, quadratic roots, real numbers, algebraic expressions and fractional operations in junior high schools, and the deformation of algebraic expressions, it is necessary to review and consolidate some of them. If there are often problems in calculation, it will become a huge stumbling block to high school study.

Second, reflect on the summary.

Many students will encounter great trouble in studying law after entering high school. Because senior high school has a lot of knowledge, short teaching time and great difficulty, some learning methods in junior high school are not applicable in senior high school. For the knowledge of senior high school, we can't think that it is natural to do more problems, because senior high school doesn't have so much time to do problems, so we must find a more effective learning method, that is, we should sum up and reflect after each study. Summarize the connections and differences between knowledge points and reflect on the deeper nature of knowledge. Third, preview the knowledge of senior one. The first semester of the new curriculum standard is generally compulsory 1, and compulsory is about 4. At present, high school adopts modular teaching, with 2 modules per semester.

The compulsory course 1 has three main parts:

Set: the most basic and universal mathematical language in mathematics. The whole high school and modern mathematics are based on set language. Be sure to learn clearly.

Function: through the study of specific functions in junior high school, learn arbitrary functions and their properties, such as monotonicity, parity, symmetry, periodicity and so on. This part is relatively difficult and closely related to junior high school. Basic elementary function: the operation of exponent and logarithm, learning exponential function, logarithmic function and power function by using the function properties learned before. There are new calculations in this part of knowledge. Learn new functions by applying the previous function properties.

The main content of compulsory 4 is also divided into three parts:

Trigonometric function: the concept of expanding angle in junior high school, involving the operation and properties of trigonometric function.

Plane vector: This is a new commonly used tool in mathematics. Many trigonometric functions can be easily solved by vector method. This method has many connections with the plane rectangular coordinate system, but it is different from the function, so we should pay attention to the difference and connection.

Triangle identity transformation: this part is mainly the operation of triangle, which belongs to many formulas and has a large amount of operation. Looking at the contents of the first semester of senior one, we can see that there is a lot of knowledge, and these knowledge accounts for a large proportion in the college entrance examination, so if you don't learn well at the beginning of senior one, it will have a certain impact on your later study. Therefore, we should take into account the differences in knowledge between junior high school and senior high school, improve our own learning methods, and finally preview the content of senior one appropriately, so as to quickly adapt to senior high school mathematics learning. In the new school year, Beijing No.4 Middle School Online School has launched the synchronous teaching content, synchronous test questions for No.4 Middle School teachers and online face-to-face courses for No.4 Middle School teachers. No matter what the teacher of No.4 Middle School teaches, the online school of No.4 Middle School will teach it. What students in No.4 Middle School study and test, students in No.4 Middle School can learn synchronously, and they can also listen to the face-to-face courses taught by the first-line teachers in No.4 Middle School and interact with the famous teachers in No.4 Middle School in real time! Ask yourself to have a new start in the new school year by the standards of famous schools!
