We can often see that some math classes are like this: some teachers speak methodically, analyze knowledge thoroughly, deduce clearly, and students listen easily and seem to understand, but they are often at a loss when they encounter variations and practical problems; Some teachers have designed many detailed questions, which are often asked and answered between teachers and students. On the surface, it looks smooth, but as a result, it is not ideal to test students' knowledge mastery and ability formation. Some teachers pay attention to refined knowledge and set aside a lot of time to practice various exercises. Although students' problem-solving ability is acceptable, it inhibits students' innovative thinking and creative potential. Some teachers let several top students play the leading role in class, such as operation, demonstration, activities and reports ... On the surface, it seems lively, but in fact, most students are accompanying guests, while some students with learning difficulties are even more confused and don't know why. After studying these seemingly perfect classes, we can easily find that they lack the charm they deserve as a good class. So what should a good math class pursue? A good class should be student-oriented. Classroom teaching under the new curriculum concept is not only a special cognitive process, but also a complete life process in which both teachers and students feel, experience and create together. At present, we should focus on the realization of students' three-dimensional goals in class, that is, whether they have acquired knowledge and skills, whether they have gone through the process, mastered methods, and how their emotions, attitudes and values have developed. A good class is student-oriented. Its core is to regard students as torches that can be lit, as self-builders of knowledge and methods, and as self-shapers of emotions, attitudes and values. Any teaching activities should be carried out around students' existing experience and future development, designed according to students' growth law, and carried out around students' "recent development fields", so as to stimulate students' enthusiasm for active exploration and make students actively participate. Make the learning process a process of sound development of students' body, mind and personality. Only by firmly grasping "student-oriented" can all teaching activities have life activities. A good lesson should be a good lesson generated under the background of the new curriculum of communication, not a step-by-step "teaching plan drama" for teachers. It is a wonderful chapter produced by sincere interaction between teachers and students and between students. The Outline of Basic Education Curriculum Reform points out that teachers should actively interact with students and develop together in the teaching process. In the classroom, teachers and students should communicate with each other, understand each other, complement each other, share each other's thoughts, viewpoints and knowledge, enrich the teaching content and seek new discoveries, so as to achieve * * * knowledge. Form a real "combination of learning and learning" and realize "learning from each other's strengths". Create situations and ignite passions. As the behind-the-scenes planner of a good classroom and the chief in the equal relationship between teachers and students, one of the main tasks of a teacher is to create an attractive learning situation, so that every learner can immerse himself in it, feel the touch of the scene, and have the desire to explore new knowledge and the impulse to advance. You can also design wonderful experiments to stimulate students' passion for knowledge; Or extract the events in life to arouse students' thinking and dilute the traces of education. 2. Subjective inquiry, in the actual teaching process, we should pay attention to students' personal experience, independent inquiry and process perception. In teaching, teachers should practice Mr. Tao Xingzhi's "Six Emancipations", give students a period of time to feel, give students a space to create and give them a stage to perform; Let them think with their brains, observe with their eyes, listen with their ears, describe with their mouths and operate with their own hands. This kind of inquiry will go beyond the scope of knowledge and extend to the field of emotion and values, and will make the classroom a paradise for students' life growth. 3. Interactive listening, wisdom sublimation. As explorers and learners in the implementation of the new curriculum, teachers should let students fully express their views and puzzles in class. Teachers should believe that "no attempt" allows students to make mistakes, learn to delay judgment, and let students learn to correct their mistakes and get up everywhere. A good class should promote curriculum reform in integration and advocate "teaching with textbooks instead of teaching" Teachers should have the consciousness of "textbooks are role models" and "the whole world is students' textbooks", and creatively integrate personal and students' experience, text knowledge and the results of teacher-student interaction. Realize the unity of science, art and humanity. Now, let's enjoy the wonderful clip of "The Formula of Multiplication of Seven" taught by Mr. Ben Lin You. Teacher: Seven is a very strange number. Many problems in ancient times were related to seven. Let's enjoy a seven-character poem (staying at night by the Maple Bridge). How many words does this poem have? Can you work it out with a formula? Student: 4728. Teacher: (showing the story of "carving a boat and seeking a sword" made by puzzles) How many pieces are there in these five puzzles? Think about multiplication formula! Student: 5735 ... Teacher: What problems related to Seven have you found in real life? Teacher: How many days a week? A person should drink six glasses of water a day, and how many glasses of water a week? Student: Six, seven, forty-two. Teacher: (showing the keyboard of the electronic organ) How many white keys are there on the piano? Are you a number? How to calculate quickly? Student: 4728. Teacher: (Showing the computer courseware, the seven dwarfs sang to the music: "One dwarf has a bed, seven dwarfs have seven beds, one dwarf has two bowls, and seven dwarfs have fourteen bowls." ) Listen to the music below and continue to make up one yourself, ok? In a word, I have a formula of "good class" in mathematics: "good class" in mathematics = "mathematical" teaching+superb teaching skills.
