The new curriculum standard points out that "students are the main body of learning and development". So, how to effectively promote the development of students in the classroom? Taking Chinese teaching in primary schools as an example, as early as the beginning of curriculum reform, our school put forward and practiced the "five concessions" in reading teaching, that is, let students read what they can read, let students think what they can think, let students say what they can say, let students ask what they can ask, and let students evaluate what they can evaluate. However, how well do students practice, think, speak, ask questions and evaluate? What are your interests? To a great extent, it also depends on the teacher's evaluation of students' art. After years of thinking and practice, the author summed up ""and achieved good results. 1, direct type. For teachers' general questions, students are easy to answer, and the answers are correct. For teachers' basic teaching requirements, students do better. Teachers can give affirmation directly, don't make a fuss, and don't moan too much: "You are a little genius, you are really something!" " You can directly encourage and say, "Correct answer, good." "That's a good answer. It seems that you are listening carefully. " . Otherwise, it will affect students to say too much or even do too much. 2. comparison. Teachers can use contrastive language to motivate students to give more accurate or comprehensive answers to teachers' thoughtful or difficult questions, such as the meaning of sentences, the image and emotion of characters, the author's writing purpose and so on. For example, "You are amazing. If you can answer such a difficult question correctly, then you can understand this sentence correctly. The teacher was not as clever as you when he was a child! It seems that it is really' the waves behind the Yangtze River push the waves before, and the generation is stronger than the generation'! " 3. Rhetoric style. The author thinks that rhetorical motivation is more suitable for students to read the text smoothly, emotionally and beautifully, and can bring beautiful enjoyment to teachers and classmates. For example, "your reading has brought us into the spring of flowers;" Your expression is more beautiful than the flowers in full bloom in spring; Your song is more beautiful than lark's; Your emotions let us feel the vitality of flowers and plants in spring; The rhythm of your language is like the sound of a stream in a mountain stream jumping happily in our ears. If we close our eyes slightly, it's like honey flowing into our mouth and sweet spring soaking in our hearts. "... 4, reward type. Concentrate on class, do your homework correctly, write neatly, and answer wonderful questions. When evaluating teachers, in addition to language rewards, a small red flower, a small flag and an item commonly used by teachers, teachers or all students can also sing a song, recite a poem or a famous saying or two for a certain student as encouragement. The effect of this kind of reward is sometimes no less than the material reward for students and the financial reward for children by parents. 5. understand. In the classroom, understanding encouragement is generally taken for students to answer wrong questions, do wrong questions on the blackboard and read poorly on the premise of enthusiasm for learning. If a classmate holds his little hand high.
