An effective way to construct an efficient classroom of primary school mathematics 1. Teaching artistically.
Teaching needs artistry, thus stimulating students' fresh thinking. Clear the preset and wait for generation. This kind? A classroom without cases? A generation of students in the classroom, rather than a complete display of the teaching structure. Open classes carry too much for teachers, and the more teachers show by default, the easier it is to ignore the development trend of students' thinking. It takes courage and profound teaching skills to practice this concept in classroom teaching. When teachers insist on their grades, both students and teachers have to pay a great price. Is it important to show a variety of methods in class, or to find a common method for a class of problems? Neither.
Students are willing to do math problems and experience the joy of success brought by overcoming difficulties when they get home, which is more important than anything else. Then, why are we stingy with the praise and encouragement to students? What we can do for students is trust, which is a firm belief. Mr. Tao Xingzhi said: Teachers' life is an artistic life. ? Teachers' language is art in artistic life. An excellent teacher should have the artistic temperament of an actor in teaching, not simply imparting and explaining knowledge, but artistically reproducing knowledge. Teachers' language is a comprehensive art and an important part of teachers' comprehensive quality. Teachers' language is the expression of teachers? Kind words? ,? Good road? It is also a necessary means to obtain the ideal education and teaching effect.
Second, what should teachers do when preparing lessons? Six preparations?
First, prepare textbooks: textbooks are teaching texts, and teachers must thoroughly understand the textbooks and know them by heart in order to master the classroom;
Second, the goal of preparing lessons: the efficiency of the classroom comes from the clarity and concreteness of the teaching objectives. Only when the goal is clear can the classroom be targeted;
Three Questions: Clever questions can arouse students' interest in inquiry and activate students' thinking. Every question should be carefully designed, and students' questions should also be expected.
Prepare blackboard writing: blackboard writing is the essence of teaching, which is to sort out and summarize knowledge, outline and design skillfully;
Five exercises: practice is not only the consolidation of knowledge, but also the expansion of the classroom. Exquisite exercises can achieve the purpose of giving inferences, and must be carefully selected;
Six students: the main body of teaching is students. Grasping students' level and analyzing learning situation are the keys to classroom success. The choice of goal setting, problem design and exercises should be determined according to the students' situation.
Third, what should teachers do when giving lectures? Five?
Do you have it in your head? Outline? -firmly grasp the curriculum standards, be familiar with the requirements of the grades and disciplines taught, and understand the requirements of adjacent grades;
Do you have it in your chest? Ben. -in-depth interpretation of the text of the textbook, only first? Put on an article and fall in love? then what Emotional resignation? Make teaching presupposition;
Have three eyes? People? -The classroom should be oriented to all students and take students as the main body;
Have four hearts? Count? -Predict and master the difficulties that students may encounter in the learning process;
Five hands? Law? -We should design teaching methods and learning methods according to the curriculum and students.
Fourth, use life scenes to stimulate primary school students' interest in learning mathematics.
Mathematical knowledge comes from life and ultimately serves life. Especially primary school mathematics, its prototype can be found in life. The new syllabus points out that everyone can learn useful mathematics and everyone can learn useful mathematics. Different people study different mathematics. ? Pupils have a certain knowledge of life, and at the same time are particularly interested in the things around them, full of curiosity. Grasping this curiosity and carrying out colorful extracurricular activities can make students' learning enthusiasm generally high, which not only makes students learn interesting, vivid and easy to understand, but also enables students to approach mathematical problems with their lives, acquire mathematical knowledge, solve practical problems and make mathematics more dynamic.
Fifth, guide students to learn to learn.
I once heard a lesson on common factor and greatest common factor in the second volume of the fifth grade. I have heard this lesson many times, and I have attended it myself, but I was deeply impressed by the teacher's teaching content. After describing the concepts of common factor and greatest common factor, it is the introduction of Wayne diagram. In this session, Mr. Zhou did not directly tell the students what a Venn diagram is, but designed a clever game: there are eight cards and two circles. The eight cards are 1, 2, 3, 4, 5, 10, 15. After the rules of the game are clearly explained, please ask two students to do it on the blackboard.
At first, the two students were very orderly, so they quickly took the cards and put them in the corresponding circles. When there was only one card 5 left on the blackboard, two students grabbed the card at the same time, and neither of them would let go. Because this card is needed by both students, it is a factor of 15 and a factor of 20. Both circles need it, but there is only one card. What should I do? At this time, the students began to think: since there is only one card, is there any good way to make the card 5 appear in the circle of 15 and the circle of 20?
The students began to discuss this issue, and immediately some students suggested that two circles can be put together and stopped moving when some of them intersect. What does this mean? Why are you doing this? Because 15 and 20 have a common factor, the intersection of two circles can be regarded as their common factor. What does the intersection of those two circles mean? What numbers should be put in this? It means/kloc-the common factor of 0/5 and 20, and this card 5 should be put here. Is there only five cards in this section? No, put the card 1 here, because it is also the common factor of 15 and 20. What about the other parts that don't cross? They are the unique factors of 15 and 20 respectively. ?
Finally, in the discussion among students, in the question-and-answer between teachers and students, Wayne diagram is thus displayed. In this process, the teacher did not teach, but through a game, using the contradiction of only one card 5, through the students' own construction process to get Wayne map. Obviously, this teacher belongs to the third kind of teacher mentioned by Mr. Tao Xingzhi-teaching students to learn, which is consistent with the new curriculum standard of mathematics: paying attention to heuristic teaching, teachers should play a leading role, handle the relationship between teaching and students' autonomous learning, and guide students to think independently, actively explore and cooperate.
In this class, students can take the initiative to participate, be willing to explore, try and make mistakes with the guidance and help of teachers, freely express their thoughts and experience the joy of success, instead of instilling the contents of books into students. There is no end to knowledge, and the meaning of teachers should be to teach students to learn. When students leave school with no teachers around, they can still learn new knowledge and skills through learning methods.
In short, teaching should be eclectic, lesson preparation should be characteristic, lesson preparation should be artistic, and students' interest in learning mathematics should be stimulated by scenes in life, so as to pursue the change from learning to learning and loving learning. Over time, teaching will get twice the result with half the effort, and students' academic performance will certainly be by going up one flight of stairs.
An effective way to construct an efficient classroom of primary school mathematics: 1. Fully understand students and strengthen targeted teaching.
The main service object of classroom teaching is students, so to achieve the goal of creating efficient classroom teaching, we must first have a comprehensive understanding of students. Only by fully grasping the students' situation can we grasp their characteristics, carry out targeted classroom teaching and promote their all-round development.
1, master students' knowledge base and cognitive rules.
When students learn new knowledge, they mainly rely on what they have learned in the past. Therefore, in order to ensure the effectiveness of imparting new knowledge, teachers must first fully grasp the knowledge base and cognitive level of each student, so as to set the initial teaching objectives. The new goals set by teachers should not exceed students' knowledge base and cognitive level, otherwise students' knowledge mastery will be broken, which is not conducive to students' mastery of new knowledge;
The teaching objectives set by teachers should not be lower than students' knowledge base and cognitive level, otherwise, teachers will repeat what students have learned. These two teaching methods are not only not conducive to the improvement of classroom teaching efficiency, students' ability and teaching quality, but will reduce teaching efficiency, make students lose interest in mathematics learning and produce negative emotions. Teachers should master students' learning situation, introduce life scenes into mathematics teaching, and improve students' learning enthusiasm.
2. Master students' non-intelligence factors.
Non-intelligence factors include many factors, including hobbies and emotions, which will have a great influence on students. Teachers should pay attention to cultivating students' learning motivation and thirst for knowledge, so that students can have a strong interest in learning, a positive attitude towards mathematics and take the initiative to participate in the process of knowledge construction, thus creating an efficient primary school mathematics classroom. Teachers can use the curiosity of primary school students to ask questions, arouse students' cognitive conflicts and give students the motivation to explore and learn. Teachers can also use the characteristics of primary school students' love to play games to introduce games into classroom teaching, so that students can not only learn mathematics knowledge through games, but also gain happy memories while learning knowledge and stimulate students' enthusiasm for learning.
Second, adopt flexible teaching methods and innovate teaching modes.
Teaching method is the carrier for teachers to impart knowledge to students, and the quality of teaching method directly affects students' attitude in class. Facts have proved that teachers' flexible teaching methods are far more effective than monotonous lectures. If teachers just explain blindly, they will not only fail to understand students' knowledge in time, but also make students feel boring and gradually lose interest in mathematics learning.
Therefore, teachers should innovate traditional teaching methods and adopt previous teaching methods. Take the essence and discard the dross? At the same time, teachers should learn new teaching methods and integrate into their own teaching mode. For example, in the process of classroom teaching, teachers can effectively organize students' learning through experiments, group cooperation competitions, extracurricular discussions, etc., which can not only help students learn to cooperate, learn to summarize their own mathematical knowledge points, but also fully mobilize students' enthusiasm.
Teachers can also tell students knowledge and truth intuitively through physical display or picture display, and let students love mathematics learning through various forms and master the methods and skills of learning mathematics. For example, in the process of learning cube volume, students can make cubes and cuboids in groups, which can not only stimulate students' curiosity, but also enable students to have a deeper understanding and thinking about what they have learned in this class. In this way, students can not only get happiness in flexible classroom learning, but also gain knowledge while feeling happy. Kill two birds with one stone? .
Third, the effective application of incentive mechanisms to enhance students' confidence in learning
According to relevant surveys, spontaneous learning is the most efficient learning mode. In addition to the above measures, we should repeatedly use the incentive mechanism to enhance students' learning confidence and cultivate students' awareness of independent and spontaneous learning. In the teaching process, teachers should seize as many opportunities as possible for students to express themselves and give them timely evaluation and encouragement. In addition, in the assessment process, we should optimize the assessment criteria, weaken the performance evaluation criteria, and try to learn from students. Observing objects? Taking this content teaching as an example, the same object may have different descriptions and judgments in the eyes of students. When different descriptions appear, teachers should try their best to understand their thinking from the students' point of view, give them affirmation from innovative thinking, and then strengthen the guidance of students' thinking mode, which will certainly receive good results.
