1. Review the introduction and reveal the objectives.

1. Review. Review the key old knowledge that students need to learn this lesson. The method adopted is to ask students directly or arrange a review of diagnostic questions. The purpose of doing this is to remove obstacles for students to learn new knowledge. 2。 Introduce the topic. It can be introduced directly or by creating situations and connecting some examples to stimulate.

Students' interest in learning can improve the teaching effect.

2. Learn new courses and understand the goals.

This is the key link to realize the class schedule, and it is also an important link for students to master the content of this class. It usually takes 15 to 20 minutes to complete. If most students can understand what they have learned by themselves, the teacher will directly set the questions and let the students read them with questions, and then the teacher will let the students solve the problems. If the content is difficult or most students can't understand it independently, teachers should explain the key points and difficulties. Of course, when explaining the key points and difficulties, we should pay attention to inspiration and induction, so as to make progress step by step, deepen step by step, and be suddenly enlightened, so as to achieve the realm of beautiful scenery, no doubt, and bright future. Sometimes analogy and formula can be used to help students understand memory, which can get better results.

Three. Practice and practice of consolidating goals

This is the stage of applying the new knowledge learned to solve problems. Attention should be paid to the rational use of students' self-study and teachers' inspiration and guidance, and the combination of teaching and practice. Teachers don't work out all the problems that students can solve by themselves. They can give examples by themselves, or let students directly implement relevant examples. For difficult exercises, teachers should pay attention to the breakthrough of difficulties and don't fight alone. How to design a few small problems, inspire and guide students to solve the problems step by step and in a simple way requires teachers' efforts. Then give the corresponding exercises to consolidate and test.
