Lesson Plan: The concept of the derivation function 1. Knowledge objectives 1. Understand the definition and concept of derivatives; 2. Master the calculation method of derivatives and their applications; 3. Understand the concept of derivative functions and their meaning. 2. Teaching focus 1. Calculation method of derivatives; 2. The concept of derivative functions and their meaning. Third, teaching difficulties 1. The concept of derivative functions and their significance; 2. Application of derivatives to practical problems. 4. Teaching process 1. Pre-lesson (5 minutes) Let students read the relevant textbook content to understand the definition and basic concepts of derivatives. 2. Definition and calculation of derivatives (30 min) a) Definition of derivatives: Introduce the definition of derivatives and their physical meaning, and guide students to understand the meaning of derivatives. b) Calculation method of derivative: explain the method of derivative solving of common functions, and demonstrate through example problems, so that students can master the basic skills of derivation. 3. Concept and Application of Derivative Function (40 min) a) The concept of derivative function: introduces the definition of derivative function and its physical meaning, and guides students to understand the meaning of derivative function. b) Application of derivative functions: Through practical problem examples, let students understand the application of derivative functions in related problems. 4. Exercises and Discussions (25 mins) a) Exercises: Organize students to do some simple exercises on derivatives and derivatives to consolidate the knowledge they have learned. b) Discussion: Guide students to think about the relationship between derivatives and derivative functions, and the role of derivatives in practical problems. 5. Homework Arrange an appropriate number of exercises for the calculation of derivatives and derivative functions to deepen students' understanding of the concepts of derivative functions. 6. Reflection on teaching 1. Derivatives and derivative functions are very important concepts in calculus, which require more time to explain and practice; 2. In the calculation method of derivatives, attention needs to be paid to guiding students to understand the physical meaning of derivatives, and at the same time, it is necessary to explain some special laws and skills of derivatives. 3. When explaining the derivation function, it is necessary to pay attention to the connection with the actual problem and guide students to apply the knowledge learned to the practical problem.
