Some teachers may say: "the textbook of beauty of sound and body is more interesting than the course of Chinese and mathematics." In order to pursue the quality of teaching, we can't turn Chinese and mathematics courses into courses with beautiful sound and body. " Are you not happy in math class? Is happiness in math class without quality? Actually, I think "happiness" can be "efficient"! Only when students feel "happy" in class can they truly become the masters of learning and achieve the goal of "high efficiency". How to make education entertaining? I think we should do the following:
1, wonderful introduction, laid the "happy" tone.
It is gratifying that the five math teachers in this competition have tried their best to create "happiness" when introducing new classes. For example, teacher Yin Haihua of Huotian Central School uses games (guess the color of paper cranes) to import; Teacher Luo Anqun of Zaoshi Central School introduced fairy tales; He Laoshi, the Liberation School, adopted children's songs for introduction. These lead-in methods are very consistent with the psychological characteristics of primary school students, which quickly attracted students' attention, stimulated students' interest in learning, and laid a "happy" tone for the whole class. As the saying goes, a good beginning is half the battle, so our math and Chinese teachers must pay attention to the introduction in class, be good at discovering "fun" and let them "learn happily". But remember that getting started should pave the way for learning new knowledge later.
2. Respect students and create a "happy" atmosphere.
The new concept of teachers and students puts forward that the relationship between teachers and students is democratic and equal. Students are emotional individuals, and teachers should respect students. Our teachers should not be above the students, but should kneel down and communicate with them, especially for students with learning difficulties, and should show more concern rather than discrimination. These five teachers have done very well at this point. Their language is kind and childlike, their teaching attitude is easy-going and natural, and their evaluation of students in class is timely and pertinent. The language and methods of encouragement are naturally diverse, so that students' personality can be respected and the joy of success can be experienced. In this classroom atmosphere, teachers teach easily and students learn happily.
3. Excavate the material and experience the process of "happiness".
"Happy" teaching is inseparable from "happy" materials, which is the source of students' happiness. How to excavate the material of "happiness"? This requires us to pay more attention to accumulation at ordinary times. There are many ways to collect materials, such as paying close attention to some life cases around or in society; Read more books, magazines and newspapers; Browse and consult relevant information on the Internet; Television, radio and other media, and so on. We record the information obtained in time and wait for the necessary processing or screening when needed in class.
Students pay more attention to "interesting, fun and novel" things in the lower grades. Therefore, the selection and presentation of learning materials and the arrangement of learning activities should fully consider students' real life background and interests (toys, stories, etc.). ), let them feel that learning mathematics is an interesting thing and are willing to approach mathematics. By 1980, middle school students began to be interested in "useful" mathematics. At this time, the selection and presentation of learning materials and the arrangement of learning activities should pay more attention to the application of mathematics in students' study and life, so that they can feel that mathematics is around them, and learning mathematics is useful and necessary, so that they are willing and want to learn mathematics. Senior students begin to have a strong sense of self-awareness and self-development, so they are interested in phenomena that conflict with their intuitive experience and "challenging" tasks. This makes us not only pay attention to the usefulness of mathematics in the selection and presentation of learning materials and the arrangement of learning activities, but also give students the opportunity to "do mathematics" as much as possible, so that they can express themselves and develop themselves in these activities, thus feeling that mathematics learning is a very important activity and initially forming "I can and should learn to think with mathematics". For example, Teacher Tan Xiaomei of Xia Dong Central School uses the real life background that students are familiar with to make the materials of simple compound statistics, and Teacher Liu Qiong of Taokeng School teaches the preliminary understanding of decimals with materials closely related to life. The materials selected by these teachers can arouse students' interest, let students devote themselves to their interested mathematics learning, experience the "happy" learning process and feel the importance and interest of mathematics learning.
In short, there are many "happy" substances in life, but we need to work hard and accumulate them carefully. When students are looking forward to math class, our math class is successful and our math teaching is full of hope.
Second, how to make the math classroom "efficient"?
Establishing a "happy" math classroom is the premise of realizing "high efficiency" in the classroom. To improve the effectiveness of mathematics classroom, I think we should also work hard on the following points:
1. Create an effective scene.
A good situation is conducive to stimulating students' desire for learning and motivation to participate, making students actively integrate into problems, actively participate in the atmosphere of free exploration and cooperation, and also helping to resolve some important and difficult points in teaching. From the perspective of modern teaching theory, the main task of mathematics teachers is to design learning situations for students, provide comprehensive and clear information, and guide students to use their brains to learn and master mathematics knowledge in the teaching situations created by teachers. However, it must be understood that the creation of situations is for better teaching, not for creating situations, otherwise the situation is just a flower shelf and loses its meaning. The ultimate goal of creating situations is to attract and inspire students to learn and fully feel the value and charm of mathematics. Then, the creation of mathematics classroom situation must be scientific and effective. For example, He Laoshi, a liberated school, created a scene of "age comparison between teachers and students" when teaching "indicating the relationship between size with letters", which made the classroom teaching achieve an efficient purpose.
2. Organize effective activities.
Create effective scenes for students and organize students to carry out effective activities. Teachers should organize students to observe, guess, operate, experiment, compare, summarize, demonstrate and a series of activities, and guide students to carry out independent inquiry, cooperation and exchange. It is effective to let students experience the generation process of knowledge and leave a deep impression in their minds. For example, Teacher Tan Xiaomei of Xia Dong Central School organized a group cooperation activity and made a reasonable division of labor in order to count the weight of senior two students. Unfortunately, some students in the group didn't really implement it.
3. Ask effective questions.
Classroom questioning is a main form of heuristic teaching in primary school mathematics teaching, which is the "core of effective teaching" and a teaching method often used by teachers. However, due to various reasons, the phenomenon of asking questions that should not be asked, repeating inefficient questions, and substituting questions for words is still widespread, which restricts the improvement of classroom teaching efficiency to some extent. How to enhance the effectiveness of classroom questioning should pay attention to the following two points. (1) Questions should be few and precise, and should be worth thinking about. (2) The questions should be difficult and moderate, and the questions designed by teachers should be answered by students of different levels through positive thinking.
4. Effective design and practice.
The design of exercises should be refined rather than quantitative, targeted, challenging, open and hierarchical. A large number of repetitive exercises with low thinking level will not only have no teaching effect, but also make students have fixed thinking and boredom. This requires teachers to design exercises effectively, so that students can consolidate new knowledge and develop their thinking through vivid and interesting exercises. The exercises designed by the teacher are more structured and interesting. An exercise designed by Mr. Luo Anqun (let students make up their own application problems and then let them solve them) allows students to know what kind of problems to be solved by "backward deduction" in essence. Make the exercise fall into an effective place.
5. Use effective resources.
With the continuous progress of society, science and technology are constantly updated, and our educational technology is also modernized. The use of multimedia replaces traditional teaching methods such as small blackboard and wall chart, which makes classroom teaching change from "static" to "dynamic", which is the progress of education. In this contest, every teacher made multimedia courseware, which made classroom teaching vivid, greatly attracted students' attention, shortened the time for teachers to write on the blackboard, and provided a guarantee for our classroom teaching to achieve "high efficiency". However, we should be careful not to pursue a fashion, and unilaterally pursue fancy in form. In the classroom, multimedia courseware is used in every link and step, which actually does not play the real role of modern educational technology. In normal teaching, we should use modern educational technology reasonably according to the characteristics of teaching content and students' cognitive level and thinking level, so that modern educational technology can be used properly, its advantages and specialties can be brought into play, and students' positive thinking can be promoted.
To make the math class "efficient", we teachers are required to study the teaching materials deeply, do a good job in teaching material analysis and grasp the important and difficult points of the teaching materials. Through the creative integration of teaching materials, we can highlight key points and break through difficulties to achieve "high efficiency". In this contest, I found the rule taught by teacher Yin Haihua, and only stayed on the rule of color. If it can be applied to shapes, objects and life, the content will be more abundant. The material of "simple compound statistics" taught by teacher Tan Xiaomei is desirable, but a lot of time is spent on filling out a single statistic, and the focus of this lesson is not accurate. We might as well use the materials of commodity prices to introduce Professor Liu Qiong's "Preliminary Understanding of Decimals". If we can continue to teach decimal reading and writing with this material, it will be easier for students to accept.
In a word, "happiness" and "efficiency" are the main themes of mathematics classroom. Let's strive to create a "happy" classroom, so that students can study efficiently in a relaxed and pleasant environment.
