The following is the teaching design and reflection on the application of the inverse number and derivative: ##1. Teaching Design ###(1) Teaching objectives 1. ** Knowledge and Skill Target ** - To help students understand the concept of the opposite number and master the method of finding the opposite number of a number. - Students would be able to master the application of the derivative in the monotonicity of a function, such as using the derivative to judge the monotonicity of a function, finding the monotone interval of a function, and finding the linear equation according to the geometric meaning of the derivative. 2. ** Course, Method, and Target ** - Through examples, the concept of the opposite number is introduced to train the students 'ability to observe and conclude. - In the teaching of derivative application, through the analysis and solution of typical examples, the students were guided to learn how to use derivative tools to solve practical mathematical problems, and improve their logical thinking ability and problem solving ability. 3. ** Emotions, attitudes, values, goals ** - It was to let the students experience the rigor and logic of mathematical concepts and stimulate their interest in mathematics learning. - In the study of derivative application, the students would feel the powerful role of derivative as an important mathematical tool in solving problems related to functions, and cultivate the students 'awareness of mathematical application. ###(2) Difficulties in Teaching 1. ** Teaching Focus ** - Understanding and application of the concept of inverse numbers. - The application of the derivative in the monotonicity of functions and the problem of tangency. 2. ** Teaching Difficulties ** - The understanding of the concept of the opposite number, especially in the case of complex numbers (such as complex numbers). - Some error-prone points in the application of the derivative, such as the accurate grasp of the relationship between the positive and negative of the derivative and the monotonicity of the function when using the derivative to judge the monotonicity of the function, and the determination of the point of contact when solving the tangency equation. ###(3) Teaching Method 1. Using the teaching method, he systematically explained the concept of the opposite number, its properties, and the application of the derivative. 2. Using the method of inquiry, the students were guided to explore the application of the derivative in the function through the analysis of specific functions. 3. Combining the practice method, the students could consolidate their knowledge of the inverse number and derivative by doing exercises. ###(4) Teaching process 1. ** import (3 - 5 minutes)** - For the part of the opposite number, show some pairs of points on the number axis, such as 2 and-2, 3 and-3, etc., to introduce the concept of the opposite number and ask the students how to define the opposite number. - For the application of the derivative, you can start with a simple function image, such as y = x^{2}, and ask the students how to determine the rising and falling intervals of the function, which will lead to the application of the derivative in the study of function monotonicity. 2. ** New knowledge lecture (20 - 25 minutes)** - ** Opposite numbers ** - Explain the definition of opposite numbers in detail: two numbers with equal absolute values and opposite symbols are opposite numbers, especially emphasizing that the opposite of 0 is 0. - Illustrate the application of the opposite number in the operation of numbers, such as a +(-a)=0. - ** Derivative application ** - Function Monotonicity - Review the definition of the derivative, and then explain the relationship between the positive and negative of the derivative and the monotonicity of the function: When the derivative of the function y = f(x)>0, the function increases monotonously in the corresponding interval; when f'(x)<0, the function decreases monotonously in the corresponding interval. - Using an example, such as <y = 3x^{2}-6x>, take the derivative <y' = 6x - 6>, let <y'=0> get <x = 1>, and then determine the monotonous interval of the function according to the positive and negative of the derivative when <x<1> and <x>1>. - Tangent problems - Explain the geometric meaning of the derivative, that is, the derivative of a function at a certain point is the slope of the tangents at that point. - Take the position of x = frac {pi}{2} as an example. First, find the derivative of x = cosx. When x = frac {pi}{2}, then y = 0, which means the slope of the line is 0. Then, find the equation of the line. 3. ** Class practice (15 - 20 minutes)** - Give practice questions about the opposite number, such as finding the opposite number of-5, reducing the number of a - (-b), etc. - Arrange exercises for the application of the derivative, such as finding the monotone interval of the function y = x^{3}-3x ^2}+2', finding the linear equation of y= n x at x = e ', etc. During the students 'practice, they would patrol and guide them, discover the students' problems in time, and correct them. 4. ** Class summary (3 - 5 minutes)** - Let the students review the concept and method of finding the opposite number. - Guide the students to summarize the application methods and steps of the derivative in the monotonicity of functions and the problem of tangency. 5. ** Homework arrangement (1 - 2 minutes)** - Write down the opposite numbers of some numbers and explain their positions on the number axis. - Arrange homework on the application of the derivative, such as a comprehensive question, which requires you to first determine the monotonicity of the function and then find the linear equation of the function at a certain point. ##2. Reflection on Teaching ###(I) Success 1. ** The effectiveness of teaching methods ** - In the teaching process, the combination of teaching method, inquiry method and practice method allowed students to better understand and master new knowledge. For example, in the derivative application section, students had a more intuitive understanding of this abstract concept by exploring the relationship between the derivative of a specific function and monotonicity. 2. ** Teaching content arrangement ** - From the concept of inverse numbers to the application of derivative, the teaching content was arranged reasonably. The introduction of the concept of inverse numbers laid the foundation for the subsequent mathematical operations. The application of the derivative, from the monotonicity of the function to the tangency problem, was in line with the students 'cognitive laws. ###(2) Deficiency 1. ** Not enough attention to individual students ** - In the classroom practice session, due to the limited time, he did not pay enough attention to some students with learning difficulties and could not fully answer their doubts. For example, in the complex application of the derivative, some students were not familiar with the application of the derivative formula and did not give more individual tutoring in time. 2. ** Grasping the teaching rhythm ** - In the new knowledge section, the tangents in the application of the derivative might be explained in a hurry. Some students might not fully understand the close relationship between the solution of the tangents equation and the geometric meaning of the derivative. ###(3) Enhancement measures 1. ** Pay attention to individual differences ** - In future teaching, more attention should be paid to the individual differences of students. More time should be reserved for students with learning difficulties in the classroom practice session, or group learning methods should be adopted to let students with better grades help students with learning difficulties and improve together. 2. ** To improve the teaching rhythm ** - Reasonably adjust the teaching pace, slow down the key and difficult content of derivative application, and add more examples and exercises to ensure that students can truly understand and master the relevant knowledge. For example, on the tangency problem, more examples of different types of functions could be added. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
