Strive to promote nine-year compulsory education in teaching, implement new curriculum reform, embody new ideas and cultivate innovative spirit.

Through mathematics teaching, students can learn the basic mathematical knowledge and skills necessary for modernization and further study of modern science and technology; Strive to cultivate students' computing ability, logical thinking ability, problem analysis and problem solving ability.

Second, the analysis of learning situation

In this issue, I continue to teach math in Class 8 (2). The students in this class have serious polarization in math scores, and many students have poor foundations and serious problems. Last semester, the final exam organized by the town, the mathematics of this class was only in the middle and upper reaches. In order to achieve ideal results in this period, teachers and students need to redouble their efforts to make up for the shortcomings, pay attention to methods and lay a solid foundation.

Third, teaching material analysis

The teaching content of this semester is divided into five chapters, and the connection of knowledge, the teaching objectives of the textbook, and the analysis of important and difficult points are as follows:

Chapter 16 Quadratic Radicals

Based on the roots of numbers, this chapter is an abstraction and extension of the concept of arithmetic square root. This chapter focuses on the simplification and operation of quadratic root, and the difficulty is to correctly understand the nature of quadratic root and the rationality of operation rules.

Chapter 17 Pythagorean Theorem

Right triangle is a special kind of triangle, which has many important properties, such as two acute angles are complementary, and the right side opposite to a 30-degree angle is equal to half of the hypotenuse. Pythagorean theorem studied in this chapter is also a property of right triangle, and it is also a very important property. This chapter is divided into two sections. The first section introduces Pythagorean theorem and its application, and the second section introduces the inverse theorem of Pythagorean theorem.

Chapter 18 Parallelogram

The main content of this chapter is to understand parallelogram and several special quadrangles. Through the operation or measurement of graphics, students can intuitively understand the essence of graphics. Through the process of inverse proposition conjecture, operation verification and logical reasoning proof, students can understand and master several graphic judgment methods and improve their mathematical thinking ability.

Chapter 19 Linear Functions

The main content of this chapter is the basic knowledge of function, as well as the image, nature and simple application of linear function. Function is one of the important basic concepts in mathematics, which reveals the interdependence and changing nature of quantities in the real world and is an important model to describe and study the changing law of the real world. This chapter is the introduction of learning function, and it is also the basis for further learning function.

Chapter 20 Data Analysis

This chapter mainly studies the statistical significance of statistics such as mean, median, mode, range and variance, and how to use these statistics to analyze the concentration trend and dispersion degree of data. By learning how to estimate the mean and variance of the population with samples, we can further understand the idea of estimating the population with samples.

Fourth, teaching objectives and requirements

Pay attention to the teaching of basic knowledge and the cultivation of basic ability, face all students, narrow the polarization, try our best to let the underachievers catch up and improve the teaching quality in a large area.

Five, the main measures to improve the quality of teaching

1, study the new curriculum standard seriously, study new textbooks, expand the content of textbooks according to the new curriculum standard, listen to lectures carefully, correct homework, guide carefully, and do test papers carefully, so that students can learn to study hard.

2. Guide students to actively participate in the construction of knowledge, and create an efficient learning classroom that is democratic, harmonious, equal, independent, exploratory, cooperative, communicative, sharing and seeking happiness, so that students can experience the happiness of learning and enjoy learning. Instruct students to write small papers and review outlines, so that knowledge can come from students' structure.

3. Guide students to actively summarize the law of solving problems, guide students to solve more than one problem, cultivate students to see the essence through phenomena, and improve students' ability to draw inferences from others. This is one of the fundamental ways to improve students' quality, cultivate students' divergent thinking and keep them in a state of thinking.

4. Cultivate students' good study habits. Tao Xingzhi said: education is to cultivate habits, and habits help students to steadily improve their academic performance, develop students' non-intelligence factors, and make up for their lack of intelligence. These habits include ① the habit of doing homework carefully, including cleaning the desktop before homework and checking carefully after homework; 2 the habit of previewing; ③ The habit of carefully reading the corrected homework and correcting it in time; ④ The habit of full preparation before class; The habit of taking notes in books; ⑥ The habit of keeping books, materials and school supplies properly; ⑦ The habit of reading math textbooks carefully.
