The following is a reflection on the teaching of Gudong: - ** From the perspective of early childhood education: - In terms of goal setting, in order to meet the language learning needs of young children, the goal was to "learn to talk about stories and use expressions and actions to act boldly". Through the introduction of expression pictures, the protagonist's expression was drawn out. During the narration, the children were asked to perform expressions and actions on the basis of learning dialogue to assist the children's language expression. For example, when encountering a Long-Haired Lion, let the children imagine its expression and feel the meaning of the story. This method made the child's language learning more lively and interesting. When guiding the child to guess the reaction of the Long-haired Lion, the child actively discussed and even debated. With the help of the teacher, the child learned to refute the other party's reasons, which was conducive to the development of the child's thinking. - ** From the perspective of junior education **: - ** Introduction segment **: Grasp the age characteristics of the younger students who like to play, and introduce the text by imitating the sounds of nature and making a "gudong" sound. Set suspense, stimulate learning interest, and create reading expectations. - ** Word Teaching **: For situations where there are few new words, focus on reading the four difficult sentences in the text. Put forward different reading requirements for the four sentences, such as reading out the feeling of "running away", reading the tone words accurately, and reading the pauses according to the punctuations to prepare for reading. - ** Text Reading Stage **: - ** Reading aloud training **: Through reading aloud, the students will think about the behavior and words of the small animals after hearing the "gudong" sound. They will grasp the key points and guide the students to read aloud. For example, let the small animals read out the panic and nervousness of the words. They will read the text repeatedly to taste the text, mobilize the students 'enthusiasm and initiative, and improve their ability to understand and use the language. - ** Character evaluation **: Use the "role evaluation" method to arrange the role performance after the students read the animal's cry. After the performance, conduct an on-site interview to let the students understand the role and feel the blind and ridiculous nature of the animal again. Deepen the understanding of the text and make the mental factors internalize and sublimate. - Grasp the key words: Guide the students to grasp the key words such as "follow, run, and call" to understand the content of the text and understand the funny things about small animals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is the reflection on the first lesson of Position: ##1. Strengths 1. ** Conforms to the law of cognition ** - The teaching segment was introduced from the real-life classroom situation, allowing the students to first have a three-dimensional understanding of the location, then to the location on the plan, then to the location on the grid paper, and finally to return to the location in life. This transformation process from intuitive to abstract was in line with the law of students 'cognitive development. It could allow students to understand concepts from shallow to deep, from easy to difficult, establish mathematical models, stimulate learning interest, and promote the generation of teaching activities. However, the introduction of the concept of number pairs was quite sudden, and it was difficult for the students to accept it. Later on, the changing seats game made up for this deficiency and deepened the students 'understanding of the meaning of number pairs. 2. ** Use teaching materials in a creative manner ** - The teaching material arrangement was to first explain the content of the teaching material situation map, then talk about the class position. The actual teaching was to first let the students say their position in the class, and then use the situation map as a reinforcement exercise. Since the discussion was about the seats that the students were familiar with, this exchange aroused the students 'interest and enriched the content of the teaching materials. It was in line with the new curriculum standards for teachers to use teaching materials in a creative manner. 3. ** Using on-site resources to simplify math problems ** - Starting from the seats that the students were familiar with, the students were asked to try to describe it themselves, organize a discussion, and finally draw out a few pairs of methods to express the position. This process wasn't taught directly. Instead, the students were allowed to express themselves in a way that they liked. The knowledge points were drawn out from the students 'mouths to make them feel satisfied and stimulate their interest in learning. At the same time, the students were allowed to abstract mathematical expressions from their existing knowledge and experience, making it easier for them to understand and accept. ##2. Deficiency In actual teaching, when the students had the confusion of (4,2) and (2,4), they did not compare in time, but were eager to complete the teaching process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There are many points worth reflecting on in the teaching of singing in music class. First of all, he had to pay attention to the students 'acceptance. Different students had different musical foundations and learning abilities. For example, some students might have a good sense of music and could read music quickly, while others were relatively weak. This required teaching students according to their aptitude, such as giving more individual guidance to those with weak foundations. Secondly, the teaching method was very important. A single teaching method could easily make students feel bored. A variety of methods should be used, such as introducing songs with stories and enhancing interaction through games. Moreover, the choice of songs also affected the teaching effect. It was necessary to consider whether the difficulty of the song was suitable for the age and level of the students. In addition, during the teaching process, the emotion and content of the song could not be ignored. This would allow the students to better understand and interpret the song. At the same time, we should pay attention to the feedback of students and adjust the teaching rhythm and methods in time to improve the overall teaching quality. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
