The first part of the eighth grade mathematics teaching work plan
First, the guiding ideology: in-depth study of lesson preparation, scientific and standardized teaching, careful correction, timely summary and reflection.
1. General principles of teaching:
Lower the base point and face all; Deepen the connotation and pursue high efficiency; Expand and extend, cultivate ability.
2. The overall goal of teaching:
Stabilize the foundation, change the edge, raise eugenics, promote top students and strive for the first place.
Second, teaching material analysis
The content arrangement of this textbook highlights the following characteristics: building a starting point for students' mathematics learning, providing students with realistic, interesting and challenging learning materials, providing students with time and space for exploration and exchange, showing the formation and application process of mathematics knowledge, and meeting the development needs of different students. In the introduction of mathematics knowledge in each chapter, let students be familiar with life examples, pay attention to students mastering knowledge through observation, analysis, synthesis, comparison, abstraction and generalization, and gradually learn to use induction, deduction and analogy for reasoning.
The teaching content of this semester consists of seven chapters: (1) Axisymmetry in life (2) Pythagorean theorem (3) Real number (4) Preliminary understanding of probability (5) Plane rectangular coordinate system (6) Linear function (7) Binary linear equations.
(1) Axisymmetry in life: Based on students' existing life experience and preliminary mathematical activities, this chapter starts with observing the phenomenon of axisymmetry in life, and intuitively understands and summarizes the related characteristics of axisymmetry from the overall perspective; Through the step-by-step analysis of simple axisymmetric figures such as diagonal, line segment and isosceles triangle, students are guided to gradually understand and appreciate the same law of axisymmetric phenomena and understand the basic properties of axisymmetric phenomena; At the same time, in simple pattern design, hemming and paper-cutting activities, students can further understand the application value and rich connotation of axial symmetry.
(2) Pythagorean Theorem: In order to enable students to better understand Pythagorean Theorem and develop their reasoning ability, the textbook designs an activity to explore Pythagorean Theorem by calculating the area of square paper, and at the same time, it arranges to verify Pythagorean Theorem by means of puzzles, trying to let students experience the mathematical discovery process of observation, induction, guessing and verification, and at the same time, infiltrate the relationship between algebraic operation and geometric figures. This chapter pays more attention to the understanding and practical application of Pythagorean theorem, and does not pursue computational complexity. After learning irrational numbers, we can use Pythagorean theorem to solve some practical problems in designing irrational number operations.
(3) Real number: This chapter first gives the concept of irrational number through puzzles and calculator exploration activities, and then introduces the concepts of square root, cubic root and open operation by solving specific problems. Because in real life and production practice, we often have to estimate the approximate value of irrational numbers, so the textbook arranges a section "Estimation of Square Root" to introduce the estimation method, including estimating the approximate value and checking the rationality of the calculation results. Finally, the textbook summarizes the concept and classification of real numbers, and introduces the related concepts, operation rules and algorithms of real numbers by analogy.
(4) Preliminary understanding of probability: The textbook first presents a roulette game on the second floor. Through experiments and analysis, let students realize the possibility of inevitable events, impossible events and uncertain events. Then through the coin toss game, students can understand the equal possibility of events and the fairness of the rules of the game. In the process of doing a lot of experiments, they can initially understand the significance of probability and realize that the possibility of events can be roughly estimated by doing experiments. Through a large number of experiments, students have a preliminary understanding of the relationship between frequency and probability.
(5) Plane rectangular coordinate system: This chapter attempts to present relevant contents with realistic themes, and presents the content of "finding coordinates from points, determining the position of points by coordinates, and establishing a simple left system of plane rectangular coordinate system" with interesting and challenging questions, trying to reflect the connection between plane rectangular coordinate system and the real world; Through "graphics in rectangular coordinate system", there are a lot of graphic transformations in real life, such as various picture processing on TV screen. For various methods to determine the position, this chapter presents common positioning methods in real life to every student through various forms of themes, including positioning methods that reflect polar coordinates and rectangular coordinates.
(VI) Linear Function: With the compilation of the second volume of the sixth grade, the design of the textbook in this chapter further embodies the "problem situation?" Establish a mathematical model? Concept, law, application and expansion mode allows students to abstract the concepts of function and linear function from the actual problem situation, and then explore the properties of linear function and its image, and finally use linear function and its image to solve practical problems; At the same time, the traditional textbook is reformed, and the special proportional function is studied first, then the general teaching order of linear function is studied, and the proportional function is included in the study of linear function.
(7) Binary linear equations: The textbook in this chapter weakens the concept and emphasizes the idea of two-level modeling. In order to let students experience the formation and application of knowledge, this chapter first establishes a binary linear equation through rich examples, which shows that the equation is an effective mathematical model to describe the real world, and introduces the related concepts of binary linear equation and binary linear equation system; Then the answers to practical problems are given naturally, and then two basic methods for solving binary linear equations are introduced: substitution elimination method, addition and subtraction elimination method; Then through several realistic problem situations, through the training of solving practical problems by row-column binary linear equations. Finally, by discussing the relationship between the solution of binary linear equations and the image of linear function, the relationship between equations and functions is established, and the image solution of binary linear equations is obtained.
Thirdly, the analysis of learning situation.
There are _ students in Class X, Grade Two, including _ girls and _ boys. Because _ _ lacks advantages in rational thinking, we should use more real-life examples in teaching activities, which are easy to understand and make them understand. Some concepts are unfamiliar to students, so we should stimulate students' curiosity, improve interest, improve efficiency and ensure quality in class.
In teaching, we should strive to cultivate students' mathematical consciousness, adopt the teaching method of group cooperation, improve students' ability to analyze and solve problems in the communication between students, and use knowledge flexibly to solve mathematical problems around them. Combined with the final level test of senior one, we should carefully classify and highlight the key points, do a good job in counseling three types of students and marginal students, and strive for a new breakthrough in education and teaching.

First, the basic situation of students:
There are _ students in Class X, Grade Two. According to the ranking of students in the final exam of senior one, the grade of Class Two (X) has declined. Generally speaking, the results have regressed on the previous basis. I seriously think that the decline in students' academic performance last semester has something to do with not assigning homework. I'm thinking about myself, too Is it because of my laziness? I am trying to find a high-sounding reason for myself: I am doing an experiment and I am trying to excuse myself. In fact, the semester is busier than before, and I am not lazy, but I can't let my children's life growth be adversely affected because of my experiments and explorations.
