History class talks about historical phenomena that have passed and students can't accurately verify. It requires students to concentrate on lectures and expand associations in order to form a complete historical representation. How to attract students' attention in history class? One of the keys is the introduction of the teacher's class, which is the introduction. Lead-in language is novel and interesting, which can attract students' attention and stimulate their interest in learning, thus receiving better teaching results; Lead-in language is boring and rigid, which often makes students lose interest in learning. So how to design the introduction of each class? Through teaching practice, the author wants to talk about some experiences. Key words introduction Historical phenomena and hot issues Poetry situational history cannot be copied and will not be repeated. It tells a historical phenomenon that has passed and cannot be accurately verified. It is difficult for students to understand and it is also very boring. Therefore, students are required to concentrate on lectures, develop rich associations, and put themselves in the historical environment at that time to think, thus forming a complete historical representation. I don't think there is a fixed model for design import. Different contents, different characteristics, different ages, different grades, in different ways, as long as it can attract students' attention, stimulate students' interest in learning and improve classroom teaching effect. Whether the introduction of a lesson is novel, interesting and attractive to students requires history teachers to collect a wide range of materials and information related to this historical knowledge; It is necessary to thoroughly understand the teaching materials, fully grasp the content characteristics of the teaching materials, and carefully design the classroom lead in combination with the age characteristics, grade characteristics, learning foundation and ability to accept knowledge of the students being taught. First, reproduce the historical phenomenon at that time and import it. Students like watching TV. Three minutes before class, they can use multimedia to play videos related to the content of this lesson, reproduce the historical picture at that time, and attract students' attention and interest in learning history. For example, when I was talking about the Sino-Japanese Sino-Japanese War of 1894-1895, I asked students to come into the classroom five minutes before class to watch the clip of the Yellow Sea Battle in the movie "The Storm of1895". After watching the clip, the classroom was quiet, and I began to exchange questions and answers with my classmates: 1. Student: What movie did we see just now? The student replied: "Sino-Japanese War". 2. What events did it reflect in the history of China? Student answer: Sino-Japanese War. From the movie just now, we can see what is the end of this war? The student replied: China failed. Let me ask again: Then, why did this war break out between China and Japan? How did this war break out? Why did China fail? What impact will the failure of this war have on China? In this class, we will discuss these problems together. The students are very interested and pay attention immediately. They are anxious to know the answers to these questions. Second, use hot issues to import. It is a very effective way to attract students to introduce new courses by using the latest hot topics. For example, in the period of World War I, the incident ⒐ 1 1 just happened, and the eyes of the whole world were focused on the United States. I introduced it like this: First of all, the video of the event ⒐ 1 1 was shown to students through multimedia. When the World Trade Center disappeared instantly, the students shouted. I asked: I believe everyone knows what the video just saw, and the students replied in unison: ⒐ 1 1 event. I began to import: when the incident ⒐ 1 1 happened, the United States was shocked and the world was shocked. People are worried about whether the third world war will break out. Therefore, people have to focus on the first two world wars again. Today, let's focus on World War I again. In this way, lead-in has deeply attracted students and fully aroused their interest in learning. Third, lead in with poetry.
