The ninth grade mathematics second volume teaching plan

First, the teaching background:

In order to strengthen the classroom teaching, improve the teaching routine, ensure the smooth development of teaching, complete the mathematics teaching in the last semester of junior high school, and make it efficiently complete the subject teaching task, this teaching plan is specially formulated.

Second, the analysis of learning situation:

This semester, my class is still Class 9 1002, and I am also the head teacher. My basic knowledge level is good, and my grades are average. We should pay more attention to them and encourage them, so that these students with poor foundation can master some simple knowledge, improve their learning enthusiasm, establish an enterprising and capable learning team, and let all students set clear mathematics learning goals and form a good mathematics learning atmosphere.

Third, the new curriculum requirements:

The third grade mathematics is implemented according to the mathematics curriculum standard of nine-year compulsory education, and its purpose is to make every student get the most suitable development in the learning process through mathematics teaching. Through the teaching of mathematics in grade three, students are educated to master basic knowledge and skills, and their logical thinking ability, calculation ability, spatial concept and ability to solve simple practical problems are cultivated, so that students can gradually learn to operate correctly and reasonably, and gradually learn to observe, analyze, synthesize, abstract and summarize. Can use induction and deduction, analogy for simple reasoning. Make students understand the origin and practice of mathematics, and then influence practice. Improve the interest in learning mathematics, and gradually cultivate students' good study habits, realistic attitude, tenacious learning perseverance and new ideas of independent thinking and exploration. Cultivate students' ability to solve problems by using mathematical knowledge.

Fourth, the position and role of subject knowledge in the whole system this semester:

The four chapters of this book cover three areas in the mathematics curriculum standards: number and algebra, space and graphics, and practice and comprehensive application. Among them, the contents of chapter 26 quadratic function and chapter 28 acute trigonometric function are the basic knowledge of basic elementary functions, which belong to the field of numbers and algebra. However, they are closely related to parabola and right triangle respectively, that is, these two chapters involve both quantitative relations and graphics, which can well reflect the mathematical thought and method of combining numbers with shapes. Chapter 27 "Similarity" belongs to the field of "space and graphics", which takes similar triangles as the core and also includes "similarity" transformation. At the end of this chapter, the induction and comprehensive application of four graphic transformations (translation, symmetry, rotation and similarity) learned in junior high school are arranged. Chapter 29 "Projection and View" also belongs to the field of "Space and Graphics". This chapter is very practical. It reflects the mutual transformation between plane graphics and three-dimensional graphics from two aspects: "painting by objects" and "thinking by images", which can play an important role in cultivating spatial imagination. For the content in the field of "Practice and Comprehensive Application", this textbook not only pays attention to arranging appropriate content in the texts and exercises of each chapter, but also adopts the arrangement of "subject learning" and "mathematical activities" to strengthen the embodiment of mathematical application. Chapter 29 of this book arranges a special study "Making Stereo Model", and at the end of each chapter arranges 2 ~ 3 math activities, through which the requirements of "practice and comprehensive application" closely related to the content of this book are implemented.

Five, four unit chapters:

Chapter 26 Quadratic Function

This chapter mainly studies the concept, image and basic properties of quadratic function, looks at the quadratic equation of one variable from the perspective of quadratic function, and analyzes and solves simple practical problems with quadratic function. These contents are divided into three parts.

Chapter 27 Similarity

The main contents of this chapter include the concept and properties of similarity graph, similar triangles's judgment, similar triangles's application example and potential transformation. The congruence studied before is a special relationship between graphs, while the similarity studied in this chapter is a more general relationship between graphs than congruence. Congruence can be regarded as a special similarity (similarity ratio is 1), and understanding congruence is an important basis for learning similarity.

Chapter 28 Acute Angle Trigonometric Function

The main contents of this chapter include: acute trigonometric function (sine, cosine, tangent), solving right triangle. An acute trigonometric function is a trigonometric function when the independent variable is an acute angle, that is, a trigonometric function that narrows the domain. Solving right triangle is widely used in practice, and acute trigonometric function provides an effective tool for solving right triangle. Similar triangles's knowledge is the direct basis for learning acute trigonometric functions, and Pythagorean theorem and other contents are also mathematical conclusions often used in solving right triangles, so this chapter is closely related to Pythagorean theorem in chapter 18 and the similarity in chapter 27.

Chapter 29 Forecasts and Views

The main contents of this chapter include the basic knowledge of projection and view, some three views of basic geometry, the mutual transformation between a simple three-dimensional figure and its three views, and the practical activities of making a three-dimensional model according to the three views. The whole chapter is divided into three sections.

Seven, phased test or inspection methods and counseling measures:

(1) Pay attention to after-class reflection, record the gains and losses of a class in time, and constantly accumulate teaching experience.

(2) Batch each assignment: the assignment reflects the effect of a class, how well the students master the knowledge, and carefully correct the assignment, so that the teacher can quickly grasp the situation and prescribe the right medicine.

(3) Check the learning results on time to ensure that the unit test is effective and timely, and the test paper will not be corrected overnight. After the exam, comment on students' psychology of wanting to know the answer immediately after using typical mistakes.

(4) Timely guidance and correction: strive for face-to-face signing and face-to-face teaching. Don't put off today's task until tomorrow, strive for every moment and firmly grasp every minute of Grade Three. Feedback after class. Implement every after-school help, check for leaks and fill gaps. Choose appropriate exercises and papers, correct homework in time, point out problems to students face to face in time and guide them to understand, leaving no difficulty for students to gain something.

(5) Actively communicate with other teachers, strengthen teaching reform and improve teaching level.

(6) Always listen to students' good rationalization suggestions.

(7) The strategic thinking of "two ends" and "middle" remains unchanged.

(8) Deepen the counseling for bipolar students.
