first, theme connotation: new curriculum advocacy: music class should take aesthetics as the core, attach importance to music practice, encourage music creation, advocate subject integration and pay attention to personality development. Then how to deal with the relationship between textbook knowledge and extracurricular knowledge expansion? So I started from students' hobbies, combined with movies, advertisements, literature, etc., and encouraged students to create and expand music according to textbook knowledge and life practice, which can activate students' desire for expression and creative impulse, show their personality and creative ability in active participation, and give full play to their imagination and creative thinking. Second, the case description [teaching clip] "Song of the Yangtze River" ... Teacher: Students, today we * * * wrote a grand and melodious "Song of the Yangtze River". The Yangtze River, the mother river of our Chinese people, is the cradle of the Chinese nation. She has nurtured hundreds of millions of Chinese children along the river, irrigated fertile land, and we sucked her milk and bathed in her grace. However, in the summer of 1998, the mother river flew into a rage, set off terrible waves, washed away houses and livestock, and mercilessly swept away her dear family. Why? (At the same time, multimedia shows pictures of the Yangtze River flood in 1998 and the People's Liberation Army's flood fighting and disaster relief. ) Health armor: (angrily) It is caused by people's indiscriminate cutting. Health B: It is caused by people not caring for the environment. Teacher: Yes, some of them are natural factors, but most of them are man-made injuries, such as indiscriminate cutting and wanton destruction of the natural environment, which makes us taste the bad consequences. Students, we should cherish our earth, pay attention to our living environment and cherish our mother river. Next, the teacher asked the students to make a TV public service advertisement with the theme of protecting the mother river and related background music. (The students can't help but say, "Ah? ！” Teacher: Have you ever seen a public service advertisement on TV about "Parents are the best teachers for children", that is, the daughter-in-law is washing her mother-in-law's feet ... (Before the teacher finished, many students said) Student: Yes, and later her son brought water and said, "Mother washed her feet.". (The classroom atmosphere suddenly became active, and the students seemed eager to try.) (The students were full of opinions, and the teacher toured each group and made some suggestions.) Teacher: Ok, let's ask the representatives of each group to talk about your creative ideas. Health A: Our background music is A Big River. Lens 1: First, there is a dense forest. Under the forest, there is a big river flowing slowly. Birds are singing and primary school students are swinging their oars. Lens 2: Through the tunnel of time, 3 years later, in a dry field, a white-bearded grandfather pointed to this field and said to his great-grandson: Do you know, son, before, this was our mother river-the Yangtze River. Scene 3: Take a close-up shot. At this moment, a muddy tear flows out of the corner of grandpa's eye, and then the tear gradually expands. Finally, the tear turns into a line: Don't let the last drop of water become our tear. (Clapping in the classroom) Student: (Looking at the classmates and pausing) Because that song is more in line with our shooting. (Other students nod and smile). Health B: Our background music is Haohan Song. Lens 1: There are dense trees on both sides, and the river is flowing happily. Lens 2: One day, a large group of people came, carrying axes and saws, and began to chop and chop. Lens 3: Suddenly, thunder roared, lightning flashed, heavy rain poured down, and the river flooded, which immediately washed away those who were cutting trees. Scene 4: A tree cutter hugs a fallen tree and says: I shouldn't bet my life! (Students can't help laughing) III. Case Analysis American educator Suna Dandek once said, "Tell me, I will forget, show me, I will remember, let me participate, and I will fully understand." This shows that the perception of music is nothing more than devoting oneself to it. Therefore, it is necessary to overcome the phenomenon that teachers occupy the classroom, leave some space for students to participate, give full play to their intelligence, connect with social reality, actively participate in music practice, enhance students' self-confidence in music performance, cultivate good sense of cooperation and team spirit, and feel the joy and sense of accomplishment of success.
