" Su Ke Version of Junior High School Physics Music's Characteristic Teaching Plan and Reflection Summing Up " ** 1. Teaching plan ** 1. ** Teaching goal ** - Knowledge and Skill Target - Let the students know the three characteristics of music: pitch, loudness and timbre. - Able to understand the relationship between pitch and frequency, loudness and amplitude through experimental exploration. - process, method, goal - Through experiments and explorations, the students 'ability to observe, analyze, and conclude was cultivated. - Let the students experience the application of the variable control method in physics experiments. - Emotions, attitudes, values, goals - To stimulate the students 'curiosity and desire to explore physical phenomena. - Cultivate the students 'awareness of cooperative learning. 2. ** Teaching Difficulties ** - emphasis - Music had three characteristics: pitch, loudness, and timbre. - The relationship between pitch and frequency, loudness and amplitude. - difficulties - Understanding the concept of timbre. - The relationship between pitch and frequency, loudness and amplitude was investigated by controlling variables. 3. ** Teaching Method ** - Experimental inquiry method: Through experiments, let the students intuitively feel the characteristics of music. - Teaching method: Explain the concept of musical characteristics and other knowledge. - Discussion method: organize students to discuss the results of the experiment. 4. ** Teaching process ** - Lead in a new lesson - Play a beautiful piece of music, then ask the students what characteristics the music they heard has, and lead to the topic of the characteristics of music. - Teaching new lessons - tone - Show the tuning forks of different frequencies. Hit the tuning forks and let the students listen to the changes in the pitch of the sound. - It introduced the concept of frequency, and the unit was Hertz. - Through experimental exploration, the length of the steel ruler extending out of the table was changed, and the steel ruler was plucked with the same force. The speed of the vibration of the steel ruler and the pitch of the sound were observed, and the relationship between the pitch and the frequency was obtained: the higher the frequency, the higher the pitch. - loudness - Beat the drum with different forces to let the students feel the change in the strength of the sound. - It introduced the concept of amplitude. - Through experimental exploration, the tuning fork was struck with different forces, and the magnitude of the vibration of the tuning fork and the loudness of the sound was observed. The relationship between loudness and amplitude was obtained: the greater the amplitude, the greater the loudness. - tone - Play the sounds of different instruments playing the same note, such as piano, violin, erhu, etc., so that students can distinguish the different sounds and introduce the concept of timbre. - It explained that timbre was related to the material and structure of the vocal body. - Class summary - Ask the students to review the three characteristics of music: pitch, loudness, and timbre, and what they are related to. - class exercise - He gave some exercises on the characteristics of musical sounds, such as determining which characteristics caused different sounds. - arrange homework - Ask the students to look for examples of using musical characteristics in their lives after class and write a short essay to introduce them. ** 2. Reflection and conclusion ** 1. ** Success ** - The experimental exploration segment was relatively successful. By allowing students to participate in experiments, such as exploring the relationship between pitch and frequency, loudness and amplitude, students would have a deeper understanding of knowledge. - There were many teaching methods. The comprehensive use of experimental inquiry, teaching and discussion methods can meet the needs of students with different learning styles. - The introduction of the new lesson was relatively new. By playing music to draw out the topic, it could attract the students 'attention and stimulate their interest in learning. 2. ** Inadequacies ** - The explanation of the concept of timbre could be more in-depth. Although students could distinguish the sounds of different instruments, their understanding of the concept of timbre might not be thorough enough. - In the classroom practice session, the difficulty level of the practice questions was not clear enough, and some students had a certain degree of difficulty in completing them. - The teaching time was not precise enough. He spent a little more time on the experiment to explore the relationship between loudness and amplitude, which led to a little tight time for the later classroom practice. 3. ** Modification measures ** - In the future, when explaining the concept of timbre, he could combine some microscopic physical models, such as the vibration mode of the sound body, to deepen the students 'understanding of the concept of timbre. - Carefully designing classroom practice questions and setting up questions of different difficulty levels so that students of different levels could receive effective training. - In the future teaching, he had to control the teaching time more accurately and arrange the time of each teaching link reasonably. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
