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 potential, logical thinking potential, problem analysis and problem solving potential.
Second, the analysis of learning situation
The ninth grade is a critical period in the learning process of junior high school, and the quality of students' foundation directly affects whether they can enter higher education in the future. At present, there are some excellent students in 1 class, and the students are very active. However, there are not a few students who don't make progress and can't keep up with their teachers. Some students have poor foundation and serious problems. In order to achieve ideal results in this period, both teachers and students should try their best to find out the missing and fill the gaps, give full play to the role of students as the main body of learning and teachers as the main body of teaching, pay attention to methods and cultivate their potential.
Third, teaching material analysis
There are five chapters in this semester's textbook. The convergence of knowledge, the teaching objectives of the textbook, and the analysis of key points and difficulties are as follows:
1. Understand the unary quadratic equation and its related concepts, and master collocation method, formula method and factorization method to solve the equation. Through the process of analyzing and solving practical problems, we can understand the mathematical model function of the quadratic equation of one variable, and further improve the basic potential of applying the equation in practical problems.
2. By studying the image and properties of quadratic function, we can use it to express the quantitative relationship in some problems, solve some practical problems and further improve our understanding and application potential of the function.
3. Understand rotation through concrete examples, explore its basic properties and appreciate its application in real life. Explore the transformation relationship between graphics, and flexibly use the combination of axial symmetry, translation and rotation for pattern design.
4. Understand the circle and its related concepts, understand the relationship among arc, chord and central angle, and further cultivate students' rational reasoning potential.

extreme
First, the basic situation:
I am a math teacher in Class 3 (1, 5) this semester. According to the characteristics of the subject, while educating students to master basic knowledge and skills, we must cultivate students' potential of logical thinking, calculation, spatial concept and solving simple practical problems, so that students can gradually learn to explore, guess and discover correctly and reasonably, and grasp the key points and difficulties in combination with teaching materials and students' reality. Establish the concept of quality education, aim at cultivating all-round high-quality talents, face all students, and make students develop morally, intellectually, physically, aesthetically and laboriously. In order to do a good job in education and teaching this semester, the teaching plan for this semester is formulated as follows:
Second, the guiding ideology:
The third grade mathematics is implemented under the guidance of the party's harmonious education and teaching policy and in accordance with the mathematics curriculum standard of nine-year compulsory education. Its purpose is to teach and educate people, so that every student can get the most suitable development in this mathematics learning process. Through the teaching of mathematics in the third grade, we can bring the basic knowledge and skills of mathematics necessary for production and further study, further cultivate students' computing potential, thinking potential and spatial imagination potential, apply what they have learned to solve simple practical problems, cultivate students' awareness of mathematical innovation and cultivate students' potential of applying mathematical knowledge to solve problems.
Third, teaching materials:
The third grade mathematics taught this semester includes:
Chapter 1 Special parallelogram.
The second chapter is the quadratic equation of one variable.
Chapter 3 further understanding of probability.
Chapter IV Graphic Similarity.
The fifth chapter is the concept of projection chapters.
Inverse proportional function.
Among them, the special parallelogram edges, the similarity of figures, views and projections are all related to geometric figures. One-dimensional quadratic equation and inverse proportional function are related to numbers and the application of numbers. Further understanding of probability is related to statistics.
Fourth, the teaching purpose:
In the new curriculum, by teaching the relevant knowledge of special parallelogram, students can go through the process of exploration, guess and proof, and further develop their reasoning and argumentation potential. They can use this knowledge to prove the related property theorems and judgment theorems of parallelogram, rectangle, diamond and square, and can prove other related conclusions and applications of related property theorems and judgment theorems. In the chapter of similar figures, by studying the concepts of the ratio of two line segments and proportional line segments, the properties and identification methods of similar triangles and similar polygons are comprehensively discussed. In the chapter of View and Projection, through specific activities, we can accumulate experience in mathematics activities, further enhance students' practical potential and develop their spatial thinking. In the chapter "Further understanding of probability", let students know the relationship between frequency and probability, and further understand how to find probability with tree diagram or table. In the two chapters of "One-dimensional Quadratic Equation" and "Inverse Proportional Function", students can understand various solutions of one-dimensional quadratic equation, and can use one-dimensional quadratic equation and function to solve some mathematical problems, gradually improve the potential of observation and inductive analysis, and experience the mathematical method of combining mathematics. At the same time, learn to summarize, organize and apply knowledge. So as to cultivate students' thinking potential and contingency potential.
V. Teaching Emphasis and Difficulties
This textbook includes several parts of geometry: special parallelogram, similar figures, views and projections. Algebra part "quadratic equation of one variable", "inverse proportional function". And further understand the probability related to statistics. The key point of "special parallelogram" is to ask students to master the basic requirements and methods of proof, and learn to reason and demonstrate the related property theorems and judgment theorems of parallelogram, rectangle, diamond and square. The difficulty is to use parallelogram, rectangle, rhombus, square and other related property theorems and judgment theorems to solve problems, such as induction, analogy, transformation and other mathematical ideas. The key point of "similar figure" is to explore the properties and identification methods of similar triangles and similar polygons by learning the concepts of ratio of two straight lines and proportional line segments. The difficulty is to explore the properties and identification methods of similar triangles and similar polygons, and to solve real life problems. The focus of view and projection is to determine the three views of a simple object through learning and practical activities, and to describe the basic geometric or physical prototype according to the three views, so as to realize the mutual transformation between a simple object and its views. The difficulty is to understand parallel projection and central projection, and make clear the data of viewpoint, line of sight and blind area. Focus on 1 of "quadratic equation of one variable" and "inverse proportional function", and master various solutions of quadratic equation of one variable; 2. Can draw the image of inverse proportional function, and can explore and understand the properties of inverse proportional function according to the image and analytical formula. The difficulty is 1. We can use equations and functions to establish mathematical models, encourage students to explore and communicate, and advocate the diversification of problem-solving strategies. The key to further understanding probability is to understand the relationship between the frequency and probability of events through experimental activities. Understanding probability is a mathematical model to describe random phenomena and understand the stability of frequency. The difficulty is to find the probability with tree diagram or table.
Teaching measures:
1. Seriously study the new curriculum standards and master the teaching materials.
2. Prepare lessons carefully, and strive to fully grasp the students' dynamics.
3. After-class tutoring for each class to check whether there are any omissions.
Communicate with other teachers attentively, strengthen teaching reform and improve teaching level.
5. Always listen to students' good and reasonable recommendations.
6. The idea of taking two ends in the middle remains unchanged.
Tisso
First, the analysis of learning situation:
This semester, I am a math teacher in two classes of Grade Three. After last semester's efforts, many students' learning atmosphere has changed greatly, their learning intentions have improved, and many students have poor self-control potential. Last semester, some students were not strict with themselves or even gave up on themselves, so they need to take corresponding measures according to different situations and educate them patiently. In addition, in the face of the senior high school entrance examination, they should have a general grasp of the students, so as to get in.
Second, teaching material analysis
There are only two chapters left this semester: circle and statistics and probability.
The main information in this chapter is the definition and properties of a circle, the positional relationship between a point, a straight line and a circle, the tangent of a circle, the arc length and area of a sector, the side development diagram of a cone, the parallel projection and the central projection, and the view. There are many concepts and theorems involved in this chapter, so it is necessary to sort out the context and accurately understand and master the concepts and theorems. The vertical diameter theorem and its inference, the judgment theorem and property theorem of the tangent of a circle are the key points of this chapter. The difficulty of this chapter is to prove the vertical diameter theorem and the fillet theorem, solve practical problems by using the properties related to circles, and describe basic geometric or physical prototypes according to three views.
The chapter of Statistics and Probability has two parts: population and sample and sample estimation. Statistics is an important data in statistical theory and application, and its basic idea is to estimate the whole by part. After introducing the concepts of population, individual, sample and sample size, this chapter introduces the statistical thinking method of estimating population with samples, taking percentage, average and variance as examples.
In addition to these two chapters, we should also review other materials in junior high school mathematics textbooks.
Third, the teaching objectives:
1. Knowledge and skills: Understand the positional relationship between points, straight lines, circles and circles, the arc length and area of sectors, the side development diagram of cones, parallel projection and central projection, three views, and master the concepts and calculations of the tangent of circles and angles related to circles. Educate students to master basic knowledge and skills, cultivate students' logical thinking potential, calculation potential, spatial concept and the potential to solve simple practical problems, so that students can gradually learn to operate correctly and reasonably, and gradually learn to observe, analyze, synthesize, abstract and summarize. Using induction and deduction and analogy for simple reasoning can improve students' interest in learning mathematics, gradually cultivate students' good study habits and realistic attitude, and master the knowledge points of junior high school mathematics textbooks and the basic requirements of mathematics subjects.
2. Process and method: Through the process of exploration, students can further understand the origin and practice of mathematics and apply it in practice. Through exploration and study, students can gradually learn to operate correctly and reasonably, observe, analyze, synthesize and abstract, use induction, deduction and analogy to make simple reasoning, sort out their knowledge around the basic requirements of junior high school mathematics textbooks and mathematics disciplines, conduct special review around the main materials of junior high school mathematics, and conduct stratification in time.
3. Emotional goals and values: through study, communication, cooperation, discussion and careful inquiry, students' interest in learning is stimulated, their learning methods are improved, their learning quality is improved, and correct teaching values are gradually formed, thus developing their emotions.
Fourthly, the importance and difficulty of teaching.
Key points:
In this chapter, the vertical diameter theorem and inference, the judgment theorem and property theorem of the tangent of the circle are the focus of this chapter.
The focus of this chapter is to estimate the overall statistical thinking method with some particularity of the sample.
Difficulties:
Prove the vertical diameter theorem and the fillet theorem, apply the properties related to circle to solve practical problems, and describe the basic geometric or physical prototype according to three views.
Statistical estimation is a statistical thought method to estimate the population with a certain particularity.
