One,
Using lead-in skillfully to make the classroom atmosphere "alive"
As the saying goes, "A good beginning is half the battle." It can be seen that the flexible use of the introduction method is the key to the success of a class. In teaching, I often use nursery rhymes, fairy tales, riddles and other forms to let students actively participate in mathematics activities and learn happily. For example, when I was teaching Little Farm, I used the nursery rhyme Counting Ducks to introduce it. With the music playing, the students happily sang their familiar songs and walked into the classroom easily. Everyone seems to be in a beautiful farm with chickens and ducks.
Second,
Classroom performance, so that students' personality can be publicized
After a period of observation, I found that many students I taught had acting talent. So in teaching, I often combine the theme map in the textbook with real life to make a pantomime. In order to attract students' attention, stimulate their interest and inspire their thinking. Then let the students perform pantomime and master the knowledge in the performance. For example, when teaching "picking pinecones", I prepared 29 pinecones in advance, and asked two students in my class to play the female squirrel and the little squirrel respectively. Let the students in the class witness the scene of squirrel mother and little squirrel picking pinecones together, which provides convenience for the teaching of adding and subtracting one digit from two digits. Because every student has personally experienced the process of picking pine cones, this class has received unexpected results.
Third, full love makes the relationship between teachers and students alive.
Mr. Lu Xun once said: "The root of education lies in love." I don't think a class without love is a good class. In class, teachers should fully respect and trust students. Only in this way can students respect and trust you and like the subjects you teach. Whenever the discipline in the class is too poor, I often say, "Would you please calm down and concentrate on the class?" When students can't answer for a while, I will say, "The teacher believes you can do it. Sit down and think about it! " "There is a girl in the class who is timid and always raises her hand. Once she finally raised her hand to answer a question, and I seized the opportunity to say, "I knew you could do it, that's right!" " "Since then, she raised her hand more often and louder. In the teacher's mother's love, students will naturally have a positive emotional experience, thus independently investing in their studies.
Fourth, expand knowledge and enrich students' knowledge.
Mathematics class should not only attach importance to the research of mathematics knowledge, but also guide students to extend the mathematics space to the society, so that students can learn all kinds of knowledge in mathematics class. For example, when teaching "waste recycling", you can tell students something about plastic recycling. Tell the students that all kinds of plastic wastes such as food packaging bags, disposable lunch boxes and plastic bags, as "white pollution", have now become global environmental hazards. General plastic products in nature take 200-400 years to completely decompose. Burying in the soil will hinder the growth of crops; If eaten by livestock, parents' digestive system will get sick, and in severe cases, they will die; If burned, it will release a lot of toxic gases; If recycled, regenerated gasoline can be produced. Educating students and recycling waste plastics can not only solve the problem of environmental pollution, but also open up new material resources for human production and life. Therefore, we should cherish and protect the environment.
When you finish the fifth question on page 29 and the ninth question on page 34 of the second volume of Mathematics of Beijing Normal University, you can introduce some knowledge about the Olympic Games to the students. Let students know that the Olympic Games is a sports event that people all over the world are equally concerned about, involved in and excited about. It is held every four years. At this grand event, athletes from more than 100 countries participated in dozens of competitions. If you can win the game, you will be regarded as a national hero. Now, the Olympic Games have been held for 27 times. On July 3, 2006, at 22: 65,438+00 Beijing time, Beijing, China won the right to host the 29th Olympic Games in 2008. Through these introductions, we can stimulate students' patriotic enthusiasm and help them establish national self-esteem and pride.
Five, life examples, let the application of knowledge come alive.
Mathematics comes from life and serves real life. In teaching, we teachers should constantly look for examples related to students' life, let mathematics come from life, refine mathematical problems purposefully, and then make mathematical knowledge come alive and let students feel living mathematics. For example, after teaching Little Farm, I provided some information to the students: "There are 8 teachers and 58 students in the classroom." Ask students to use "much more" and "much less" to describe the quantitative relationship between teachers and students. Let students apply what they have learned. When I finished the fourth question on page 25 of the second volume of Mathematics in Beijing Normal University, I used the game of "grabbing chairs" to inspire students. Let the students understand: 42 children, 30 chairs, one chair for each, children without chairs have 12. Through games, students' thirst for knowledge has been greatly stimulated, and mathematical problems have also been concretized, lived and visualized.
In short, the current primary school mathematics classroom is no longer a stagnant pool, nor is it a simple instillation of mathematical knowledge, but should be a mirror to test students' intelligence and ability. Teachers should actively pay attention to each student's emotional experience, create a relaxed and harmonious learning atmosphere, and let students participate, explore and communicate independently. Realize "Nine-year Compulsory Education Mathematics Curriculum Standard": "Everyone learns valuable mathematics; Everyone can get the necessary mathematics; Different people get different development in mathematics.
