2019 National Middle School Mathematics Teaching Plan

The 20th grade mathematics teaching plan of the middle school in 2019. The basic situation of the students:
The number of students in the 2009 full-year class is 121. The average scores of the final exams for the next XX students are divided into ×× points. Overall, the results are retrogressed on the basis of the previous ones. In the mastery of the students' knowledge, the whole grade has been polarized. For eugenics, the knowledge can be thoroughly understood, and the internal relationship between knowledge is clear. For the undergraduates, the simple basic knowledge is not effective. Mastery, poor performance, in geometry, due to the lack of triangle congruence and the corresponding knowledge of the Pythagorean theorem, students' thinking training in reasoning is flawed, students lack a deeper understanding of the corresponding quantitative relationship in the quadrilateral. For many children, there is a fear of geometry, and the relevant knowledge is not well understood. The current textbooks on algebra reduce the difficulty of children's calculations. For some simple calculation questions, when they explain new lessons, they can calculate quickly and well, but after a long time, students forget too fast. The experience, students based on a broad and in-depth understanding to make knowledge in all aspects to establish an organic connection, is the most difficult to forget, but in the current requirements, students are still missing in this regard. In terms of knowledge, students learn about inequalities, integer multiplications, formulas, opportunities, translations and rotations, and quadrilateral learning, and lay the foundation for children's future study. This school will also learn irrational and real numbers in algebra during this semester. The understanding of the logarithm, the learning of the function, the proportion and similarity will also make the children leap in the understanding of mathematics. The previous study has laid a good foundation for this period of study. The most worrying thing is the poor students in the class, in any case, as much as possible to keep them moving forward with the class. In terms of learning ability, the ability of students to actively acquire knowledge outside the classroom has improved. In the previous semester, the children were encouraged to buy their favorite reference books. Through their own efforts, some children’s mathematics has been significantly improved. Continue to encourage qualified children to broaden their horizons of knowledge. Make the children the most important year in the middle of the country: the second day, there is still one period of time to get to the next level. More hope that they can buy interesting extracurricular readings. In this semester, students' logical reasoning, logical thinking ability, and computing ability need to be strengthened, and students' overall performance should be improved. Extracurricular knowledge should be supplemented at appropriate time to expand students' knowledge. In the current semester, certain students must be drawn. Time to tell the children about the new concept geometry, use the area to prove the relevant knowledge of the question, improve the quality of the students; in the attitude of learning, most students can concentrate on the class, actively invest in learning, a few students The difficulty in mathematics makes them a kind of abandonment mentality for mathematics. Most students can complete the classwork homework. A small number of students need teachers to supervise. This minority student also becomes the focus of teachers, classroom homework, students. The quality of the completion is to be discounted. Since the previous semester did not assign homework to the students during the experiment, the activities of the students were extracurricular, and the children were more sturdy. It was a pleasure, which also brought a negative effect. The teacher’s tasks are less, the students’ consciousness is reduced, and the learning atmosphere is weakened. This is the semester. A problem solved; the students' learning habits are not ideal, the habits of preparation, the habit of summarizing, the habit of self-study to concentrate on learning, the habit of correcting mistakes, and the need to strengthen, need the supervision of teachers to do, Tao Knowing that education is the cultivation of habits, this is the focus of attention in this period of teaching . In the previous semester, the students' academic performance has declined, and they have a certain relationship with the non-arrangement. I am also reflecting on myself. Is it because of my laziness, I have to give myself a high-sounding reason: I am experimenting, I am In the process of exploration and excuses, in fact, the previous period was more busy than before, and it was not lazy, but it could not be adversely affected by the growth of the child's life because of his experiments and exploration. So be sure to complete your goals this semester.

Second, the textbook analysis

The content of this semester, a total of five chapters, the connection of knowledge before and after, the moral education factors of the textbook, the analysis of the major and difficult points are as follows:

Chapter 16 The Opening of the Number This chapter mainly studies the square root and the cube root, the concept of the quadratic root and the four mixed operations, the real number and the number axis and its related knowledge. This chapter is a milestone in the study of children's countries. They need to move from rational numbers to irrational numbers. The understanding will expand from rational numbers to real numbers. It will further deepen the understanding of logarithms and expand students' mathematical horizons and boundaries. Real numbers are The basis of subsequent learning content until the introduction of plural is the main content of the students involved. Starting from the practical problems, the textbook sums up the concept of square root and cube root, and then expands the four-hybrid operation of the root type, and then proceeds to the real number to complete the expansion of the logarithm system. The focus of this chapter is on the concept of square root and cube root, the simplification and operation of quadratic roots, and the concept of real numbers. In the course of teaching , students should fully discuss and think, summarize and summarize, and experience the rough development of the concept and the proficiency in the process of knowledge development and application. Classrooms are about to let the children master, don't hope for extracurricular, otherwise it will increase the number of poor students.

Chapter 17 Functions and Images The study in this chapter will bring another great leap in students' understanding. Students should learn from the constant learning into the learning of variables. It is an in-depth study after equations and inequalities. The function is an important mathematical model that characterizes and studies the quantitative relationship between the real world. It is also an important mathematical idea. The main contents of this chapter are variables and functions, plane Cartesian coordinate systems, functions of functions, one-time functions, inverse proportional functions and exploration and practice. The focus of this chapter is on the definition of functions, the range of values ​​of functions, the functions of one-time functions, and the properties and images of proportional and inverse proportional functions. The difficulty is the understanding of the definition of the function. In the actual application, the range of the value of the self-variable is determined, and the application of the first function, the proportional function and the nature are applied to solve the actual application problem. Through the study of this chapter, we can master relevant knowledge, and at the same time develop a combination of thinking and thinking methods, algebra, equations, functions, graphics, and Cartesian coordinates to think, explain and complement each other. Learning, more and more, the more important it is, through the study of this chapter, we must lay a good foundation for the combination of numbers and shapes. Develop students' awareness of application. The study in this chapter is difficult for middle and upper-middle children, mainly because of the difficulty in understanding knowledge and difficulty in the mutual conversion of knowledge, such as the rapid conversion of a functional analytic to its equivalent. The image can be created in the mind, as well as by the function image being quickly converted to its equivalent analytic expression, or by not seeing the function analytic. The key to solving this problem is to ask students to draw more pictures, think more, and slow down the teaching progress appropriately. The degree to which knowledge is to be proficient in conversion, and requires that this knowledge be mastered in the classroom.

Chapter 18: Similarity of Graphics The study of this chapter will make children's understanding of geometry also leap. The previous learning is mainly congruent transformation, whether axisymmetric or central symmetry, translation or rotation, its essence is congruent transformation, For the relationship between line segments, most of the relationship between the two line segments. After entering this chapter, many times it involves the relationship between the four lines and the mutual constraints and harmony. The difficulty of the proof is significantly increased. After the circle, much of its knowledge depends on similar basic theories. In the study of planar geometry, "similarity is the key." The focus of this chapter is on the nature and characteristics of similar graphics, the judgment and properties of similar triangles, and the use of Cartesian coordinates to study chart transformation. The difficulty is the nature of the proportional line segment, the judgment and nature of similar triangles, and their application. Through observation, measurement, drawing and reasoning, students should experience the process of acquiring knowledge, emphasize sensible reasoning, inject symmetrical thoughts into students, pay attention to the use of feature graphics, and pay attention to the positional memory of graphics instead of letters. The memory can greatly shorten the student's learning time, and the proportional transformation must reach the level of freewheeling. These tasks should be solved in the classroom.

Chapter 19 Solving the Right-Angle Triangle This chapter is the basis of the trigonometric function. The knowledge in this chapter is more intuitive. The mathematics comes from life, and it also acts on knowledge and solves practical problems in life. It is also a deepening process for students to understand mathematics knowledge. The focus of this chapter is on the Pythagorean theorem and its proof, the corner relationship of right triangles, and the solution of right triangles. The difficulty is to use the Pythagorean theorem to solve practical problems, to understand the acute angle triangle function and to apply it rationally to solve practical problems. The key of this chapter is to memorize the special acute-angled triangle function. Proficiency in the transformation of the trigonometric definition and its application, and fully utilize the two characteristic graphics in this chapter, can greatly shorten the learning time of students and enable children to put knowledge. Mastery. In teaching , we should pay attention to the study of theoretical knowledge. The theory of learning is to solve practical problems better. At the same time, we should emphasize practicality and research in the teaching according to the concept of new curriculum reform, and highlight the consciousness and process of learning mathematics and using mathematics. The application of the Pythagorean theorem and the trigonometric function is as close as possible to the actual problem.

Chapter 20 Data Sorting and Preliminary Processing This chapter is based on the further study of statistics and probability. The main content of this chapter is to select the appropriate chart for data collation, the concept of extreme difference, variance, standard deviation and its calculation, and rational analysis of the size of opportunity. Difficulties to draw a good picture of the selected graphics, the calculation of variance, the analysis of the size of the opportunity. In the process of teaching , students should experience the process of collecting and organizing data, and the students should cooperate and explore activities. Select questions to stay close to the student's life and use the calculator to process the data.

Third, the current teaching tasks:

Through the study of this period, in the knowledge and skills, learn the relevant knowledge of square root and cube root, learn the real number; master the calculation or simplification of the quadratic root, understand the definition of the function, grasp the understanding of the first function, the inverse proportional function Nature and image and its application, the method of cultivating the combination of numbers and shapes, mastering the proportional line segments, triangle similarity, the Pythagorean theorem, the definition of the trigonometric function and its application, solving the right triangle, grasping the correlation in the data collation and preliminary processing content. Through the study of this semester, students should take a step in the understanding and understanding of mathematics. In terms of emotions and attitudes, through this period of study, students realize that mathematics comes from practice and counteracts practice, understands the quantitative relationship between graphs in real life, cultivates students' realistic and serious learning attitudes, and stimulates students' interest in learning. To cultivate students' love for mathematics, love for life, find happiness in democracy, harmony, cooperation, inquiry, order, sharing, and feel the joy of learning. In the process and method, students actively participate in the exploration of knowledge, experience discovering knowledge, discover the inner relationship between knowledge, let students experience the path of discovering knowledge, and achieve the purpose of profound understanding and mastery of knowledge. In the realm of these activities, improve students' hands-on practical ability, improve students' logical reasoning ability and logical thinking ability, self-exploration, problem-solving ability, and improve computing ability, so that all students in mathematics There are different developments, as close as possible to the maximum value of their development, to cultivate students' good study habits, to develop students' non-intellectual factors, so that students can subtly accept the dialectical materialism and improve the quality of students.

Fourth, the main measures to improve the quality of subject education:

1. Seriously do a good job in teaching six. Taking the teaching six seriously as the main method to improve the performance, carefully study the new curriculum standards, delve into the new teaching materials, expand the content of the teaching materials according to the new curriculum standards, conscientiously attend classes, correct homework, conscientiously counsel, carefully produce test papers, and let students learn to study hard. .

2. Interest is the best teacher, Einstein said. Inspire students' interest, introduce mathematicians, mathematics history, introduce corresponding mathematics interest questions, give mathematics extracurricular thinking questions, and stimulate students' interest.

3. Guide students to actively participate in the construction of knowledge, create a democratic, harmonious, equal, independent, inquiring, cooperation, exchange, sharing and efficient learning classroom, let students experience the joy of learning and enjoy learning. Guide students to write small essays, write review outlines, and make knowledge come from the construction of students.

4. Guide students to actively summarize the rules of solving problems, guide students to solve multiple problems, and resolve multiple ones. Train students to see the essence through phenomena and improve students' ability to give inferences. This is one of the fundamental ways to improve students' quality and cultivate students' divergent thinking. Let the students be in a state of thought.

5. Guide the teaching with the concept of the new curriculum standards, and actively update the educational concepts inherent in your mind. Different educational concepts will bring different educational effects.

6. Cultivate students' good study habits. Tao Xingzhi said: Education is to cultivate habits, help students to steadily improve their academic performance, develop students' non-intellectual factors, and make up for the lack of intelligence.

7. Guide the establishment of “extracurricular interest group” civil organizations, carry out a variety of extracurricular activities, carry out research on the number of questions, extracurricular investigations, operational practices, and drive class students to learn mathematics, while developing the specialties of this part of students.

8. Conducting stratified teaching , setting up the assignments, setting a, b, and c. The three types of tiered layouts are suitable for poor, medium, and good students. The questions in the classroom take care of the three types of students, such as good, middle, and poor, so that they all wait. development of.

9. Carry out individual counseling, improve the ability of eugenics, and lay a solid foundation for the basic knowledge, poor students, some key knowledge, and poor coaching, which will pave the way for the development of poor students.

10, standing at the height of the system, so that knowledge is built in a system, rising to the height of philosophy, the eight parties connected, seamless, so that students learn easily, remember firmly.
