First, let the evaluation language activate the mathematics classroom
Evaluation language should be eclectic, and students' distinctive personality should be publicized. Teachers' classroom evaluation language should be flexible and diverse, and pay attention to innovation, so that students can listen, love and never tire of listening; To be eclectic, in addition to changing languages frequently, we can also combine preset languages with random languages and adjust the tone, intonation and rhythm in time according to the classroom atmosphere.
The evaluation language should be sincere and sincere in order to arouse students' emotional waves. As the ancients said, those who touch people's hearts should not worry about their feelings first. Teachers' evaluation language should be heartfelt, and students' praise should be sincere and cordial. There is a foreign classroom teaching case that makes me think deeply: after the students get it? 4+5=8? After the conclusion, the teacher commented in three sentences:? It's good. Very close to the correct answer. Who has a different opinion? The first sentence is to praise the students for daring to express their opinions. The second sentence is an affirmation of students' active thinking; The third sentence is a euphemism for information that is not answered correctly. Teachers use emotional and concise language to comment, just like Spring Breeze, which warms students' hearts, makes emotional ripples in students' hearts, gives them spiritual comfort and stimulates their enthusiasm for learning.
Second, improve learning methods and cultivate students' ability
In order to make students develop vividly, actively and actively in quality education, teachers must improve teaching methods and strive to build an efficient curriculum structure. Excellent classroom teaching? Study? Words, let students from? Study? Turn to train students? Can you learn? ; Highlights? Think? Words, let the students? Learn to answer? Turn to train students? Study? ; Highlights? Le? Words, let the students? Want me to learn? Turn to train students? I want to learn? .
In teaching, it is an important premise and guarantee to use flexible, diverse, efficient and novel teaching means and methods to stimulate interest. Therefore, in my teaching thinking activities, I not only pay attention to the results of thinking activities, but also pay attention to the analysis and display of the formation and development process of concepts and formulas, and show the ideas for solving problems. For example: reading? Cylindrical lateral area? When calculating, most students think that the cylinder lateral area expansion diagram is a rectangle through preview and hands-on operation. One of the students asked: can the side area development diagram of a cylinder only be rectangular? This question aroused everyone's interest. So I inspired the students to unfold, rolled up the prepared school tools and unfolded them, thinking and discussing with each other while observing. Finally, a student said: If the circumference and height of the bottom surface of a cylinder are equal, the side expansion diagram is a square. Another student said that if you cut diagonally along the side of the cylinder, the side expansion diagram is a parallelogram. Thus, lateral area's formula of cylinder is obtained from several different angles: S= perimeter of bottom surface? Tall man.
Third, the effectiveness of the transfer.
As an important part of regular teaching, mathematics homework is not only a continuation and supplement of classroom teaching, but also an important way of teaching information feedback. Students' homework is not only used to understand and consolidate what they have learned, but also to promote students' personality development, stimulate their innovative potential and improve their practical ability.
1. Pay attention to diversity in work layout.
The diversity of homework not only prevents students from facing simplicity? Computing applications? This result is monotonous and boring, and it can stimulate students' interest in learning mathematics. For example, the class assignments I assigned were previewed according to the outline; There is also reading, such as some operational properties and formulas; In the form of diary, such as the content closely related to life, as well as the confusion, harvest and thinking in the new teaching; Written, such as exercises in textbooks or topics given by teachers. The principle of assigning homework is that the homework in the middle and senior grades is small and precise, and the lower grades must practice, do and give feedback in class.
2. Pay attention to the level of homework layout.
The formation of intellectual skills is a process from understanding to satisfaction, from satisfaction to familiarity, from familiarity to cleverness, which requires teachers to proceed from textbooks and students' actual conditions, taking into account students' differences, and to achieve step by step, from shallow to deep, from basic to variant, from single to comprehensive, from closed to open. Different requirements are put forward for students at different levels, so that students with learning difficulties can consolidate basic knowledge, intermediate students can consolidate basic skills, and excellent students can optimize their knowledge structure. According to the knowledge structure of classroom teaching and the actual situation of students mastering knowledge, different extracurricular assignments are provided for students at different levels to choose from. For example, according to my mastery of correcting classroom assignments, I divide students into three groups: group A does basic problems to consolidate new knowledge; Group b does variant questions to form skills and improve their ability; Group C does extended questions or open exercises.
3. The homework layout should pay attention to exploration.
Effective mathematics learning activities cannot rely solely on imitation and memory. Students should really understand and master mathematics knowledge and skills through hands-on practice, independent exploration and cooperative communication, so as to gain rich experience in mathematics activities. Therefore, when assigning homework, teachers should carefully design some exercises with less time, high quality, large amount of information and strong expansibility according to the teaching content and students' existing experience in mathematics activities. Or design some exploratory homework based on students' thinking, discussion and cooperation, so that students can gain something from practicing a topic and realize the law in practice, so as to achieve the effect of drawing inferences from one example to another.
Four, contact with real life, teaching and educating people
Primary school mathematics has a wide range of uses and is closely related to real life. There are many examples and exercises in the textbook, and there are rich ideological and moral education contents between the lines, especially practical problems. The purpose of arrangement is to edify and infect students through the meaning of applied problems and carry out moral education. For example, China has a vast territory, with a distance of 5,200 kilometers from east to west, which is equivalent to 5,255 of the length from north to south. How many kilometers is the distance between north and south? Through concrete data and calculation, I let students know the land area of our great motherland, the vast territory of our country and enhance national pride. When teaching how to find a circle, I take the story of mathematicians Zu Chongzhi and Pi as the content, educate students about the splendid history of Chinese civilization, arouse their enthusiasm and pride, make students get the education of loving their hometown and motherland when doing the problem, and arouse their strong sense of responsibility to study hard to revitalize China.
In short, in the future teaching, we should start from our own teaching practice, take classroom teaching as the starting point, pay attention to teaching effectiveness, boldly practice and explore, and strive to create a novel and efficient mathematics classroom.
