Under the concept of new curriculum reform, junior high school mathematics thesis advocates that mathematics education should be geared to all students. We emphasize student-centered teaching activities, but we cannot ignore the leading role of teachers. Teaching activities are the most creative and flexible activities, and only by proceeding from reality can we achieve results. Junior students are talkative, inattentive and have poor restraint. In class, I often play for a while and learn things that have nothing to do with study for a while. Influenced by traditional ideas, teachers will regard these as students' shortcomings, force them to attend classes and restrain them. Some people still think they have ADHD. Most teachers also make students sit in a line or a posture, binding their hands and feet in class, limiting their thinking and making them completely passive. Students are bitter and tired after a class, so in the long run, children become more and more unwilling to study, and more and more students become underachievers, so they feel tired of learning and accumulate over time, delaying their lives. In view of the above situation, students should study hard and solve the problems they like to study.
First, create a situation to stimulate students' interest in learning
Mathematics originates from life, and life is full of mathematics. Teachers should create a good mathematics learning atmosphere for students and let them revel in the mathematics situation. The situation here mainly means that teachers put students in the atmosphere of learning mathematics by telling stories, creating life scenes and multimedia courseware. Students in the lower grades of primary school love to listen to stories. According to this psychological characteristic of students, I often combine the mathematical knowledge in books with real life and make up stories to attract students' attention, stimulate their interest in learning and inspire their thinking, so as to achieve better teaching results. The use of multimedia courseware in classroom teaching is not only informative, but also illustrated. Vivid pictures and beautiful sounds are easy to arouse students' interest in learning, which accords with the psychological characteristics of junior students. It can not only strengthen students' memory, but also show them unlimited knowledge space, leave them enough time to think and exercise, and stimulate their desire for information and new knowledge.
For example: teaching? 10? At that time, an interesting multimedia courseware was used to lead out: 10 digital doll went for an outing, with 9 being the biggest and the captain. 9 Order other numbers to line up. He saw that 0 was the smallest, so he went to 0 and said proudly, You are so brainless, you are too small compared with me! ? I'm very sorry to hear that. At this time 1 went to find 0 and came up with a good way to deal with 9 with 0. Guess what 1 and 0 came up with? Digital doll 1 Say:? I'm standing at 0, greater than 9, right? In this way, not only children are interested in learning new lessons, but also students feel that there is mathematics everywhere in their lives, which stimulates students' interest and motivation in learning mathematics, and at the same time, students' observation ability has been exercised and cultivated.
Second, consolidate the memory and deepen the game.
Practice is an important means for students to acquire knowledge, form skills and develop intelligence. Junior students are not interested in a lot of boring oral and written calculations, and even get bored, and their study is in a passive state. If the practice content is included in the game, it can help them get rid of boredom, stimulate their passion to actively participate in the practice, get twice the result with half the effort, and experience the joy of success from it. For example, when doing oral arithmetic, the teacher can use the speed relay race to see who can calculate quickly and accurately. The addition arithmetic game is suitable for students to learn after learning one digit and adding one digit; After students learn simple operations of addition, subtraction, multiplication and division, in order to deepen their understanding, the game of mathematical shooting is a good choice. The game presents questions and many answers to choose from, and allows students to answer within the specified time, which not only examines the content of students' classroom learning, but also cultivates students' ability to observe and choose quickly. Teaching? Composition and decomposition of numbers? When I designed it. Looking for friends? Game: Children who participate in the game wear digital cards, which are made up of? Looking for a good friend? Melody, find friends with each other, the numbers on the headdress can form a number that needs to be decomposed, and they are good friends. For example, 2 plus 6 equals 8; Three plus five equals eight. 2? And then what? 6? They are a group of good friends. 3? And then what? 5? They are a group of good friends. Students feel the abstract ideas of mathematics in intuitive and relaxed games, which makes them feel happy. Of course, in the specific process of education and teaching, teachers need to fully integrate resources, make clear the specific game operation content to students, and let students really apply the mathematics knowledge learned in class to extracurricular activities and extend it to life.
Play and play are children's nature. In the classroom, teachers organize students to carry out appropriate game activities, which not only helps students develop their physical strength, intelligence and communication skills, but also helps to stimulate students' interest in learning.
Third, explore hands-on operation independently and cultivate students' thinking.
Educators should teach according to children's nature, and human knowledge embodies knowledge, emotion and morality. Students' knowledge is perceived from experience. I don't remember what I heard, but I was impressed by what I saw and remembered what I did. Junior students are curious and active. In view of this feature, I attach great importance to students' hands-on operation in class. Let students use a variety of senses in operation and acquire knowledge through positive thinking. In this way, meeting the needs of children's development is conducive to students' thinking. Every new lesson requires students to operate. When operating, they should give students operating requirements, that is, look at the meaning of the problem clearly and think about it. According to the requirements, what do you do first, what to do next and how to do it. Resolutely overcome the problem of not thinking and doing things blindly. For example, if you teach two-digit plus one-digit carry addition, the students say or calculate 24+9=33, and the teacher asks how you worked it out. Let the students start to swing and let them think about what to swing first and then what to swing. Then, let the students show off before the stage. Through inquiry, observation and other forms, students can gradually understand the calculation and master the calculation method from concrete to abstract. 4 and 9 add up to 13, which can be bundled into a bundle of three. Add up the original two bundles, so it is 33. After the students finish writing, give them a time to reflect and let them think about what I put first, then what I put, and what kind of results I get. In this way, from perceptual representation to abstraction, the whole process of actual operation is deeply imprinted in students' minds. On this basis, let the deskmate talk about the process of pendulum. First-year students' expressive ability is poor, so as to cultivate students' linguistic expressive ability. At the same time, everyone has the opportunity to speak and get exercise. Then report to the students by name, which not only highlights the individual, but also gives consideration to the whole, so that students can speak clearly and think smoothly. This kind of teaching is not only conducive to the development of students' thinking, but also conducive to students' understanding and mastery of knowledge. Then cultivate students' interest in learning mathematics and improve their ability to use knowledge. Let students explore, discover and solve problems themselves, enjoy the fun of creation, get the joy of success, and truly become the masters of learning.
Fourth, in the competition, study hard and be positive.
Competition is an effective means to stimulate students' learning. Junior students are eager to learn and express themselves, hoping to get the trust and praise from teachers and classmates. In teaching, can it be done? Compare? 、? Trying to be a little mathematician in an arithmetic contest? And other learning competitions, so that students can learn knowledge, increase their talents and constantly improve their learning enthusiasm. In teaching, I often organize? Let's compete and win the red flag. In such competitions, students have strong interests, high spirits and lively thinking, and gain knowledge and wisdom through playing. With the implementation of the new curriculum, which takes everything for students' development as the basic concept, it is necessary for us to reposition its value from a new perspective and conduct new exploration and practice, which will be a meaningful attempt to integrate math games into the classroom more appropriately.
2. With the in-depth understanding of culture in today's society, all walks of life pay more attention to education and teaching, and some basic mathematics abilities of primary school students are developed at this time, so it is imperative to study the effectiveness of primary school mathematics teaching.
Keywords: mathematics teaching; Teaching language; Ability to ask questions; Teaching effectiveness
Mathematics in the lower grades of primary school plays a decisive role in the whole primary school stage. What does the standard think? Learning mathematics is one? Do math? Process? Build a platform for students to observe and communicate, and let them know as much as possible about the origin, development and application of mathematical knowledge. Initially, let students develop good study habits and maximize their ability to learn mathematics.
First, the use of teaching materials and teaching strategies
If students want to master as many knowledge points as possible in classroom learning and improve the quality of mathematics teaching, they must study the teaching materials seriously, so as to understand them deeply. Only by understanding the textbook can we teach better. Distinguish what is the goal of teaching and master the basic knowledge points of teaching, so as to ask some simple questions to children; It is also a necessary skill for a teacher to distinguish the key points and difficulties in teaching and master the learning direction of students in teaching; In teaching, we should know which questions belong to expanding questions and which questions belong to exploring questions, so that students can communicate, discuss and explore in class. Secondly, we should understand children's learning process from the perspective of children's age, put forward some effective questions that children can answer more appropriately from the perspective of children's thinking mode, guide children to think spontaneously, achieve the purpose of expanding students' thinking level and improve the quality of mathematics teaching. At the same time, we all know? Is the subject of mathematics learning a student? Therefore, whether it is a new teaching or a practical course, we should pay attention to teaching methods. In the new teaching, students are the main body, and teachers should stand on an equal footing with children, discuss teaching contents like friends, narrow the distance with children, eliminate children's psychological obstacles and pressures, and let children really do it in a relaxed and stress-free environment? Want me to learn? Become? I want to learn? ; In practice class, teachers should use different forms and types of exercises to make the class lively. For example, when teaching multiplication formula, take one child to tell the answer, and other children can tell multiplication formula in the right situation, so that children can act as small teachers themselves. In this way, the children not only made judgments, but also consolidated the multiplication formula; Or through the form of group competition to complete multiplication recitation, so that the original boring recitation suddenly becomes relaxed and happy, and also improves children's interest in learning. Give appropriate praise or rewards to the winning team to promote students' learning motivation.
Second, design teaching according to the age characteristics of junior students.
Students in the lower grades of primary school are young and have little knowledge of mathematics. Classroom activities are presented in the form of games, operations, dialogues and exchanges, and students are encouraged to experience the process of activities and accumulate experience in activities. Therefore, teachers should design teaching courses according to the age characteristics of students. A preliminary understanding of multiplication? In this part, let the students do it themselves, operate and draw pictures. Feel the meaning of several identical numbers personally, so as to deepen the understanding and knowledge of this part of knowledge again and again, so as to truly understand the significance of multiplication to later teaching? Division within the table? Lay a good foundation for learning and enhance students' confidence in learning mathematics.
Third, refine the teaching language.
Language is an art and an important means to accomplish the task of mathematics teaching. No matter how rich your teaching AIDS are and how exquisite your teaching methods are, if you don't have a well-organized language, you won't get good teaching results. Therefore, teachers should also consider the refinement of teaching language when preparing lessons. Especially for children in lower grades, we should use children's easy-to-understand language more. What is language refinement? It's not that a teacher can be called language refinement if he doesn't explain in class, but that the language should be in place when he explains in class. When it comes to the ideas and key points of imparting knowledge, children can understand it at once, which is a refined language. When teachers explain and ask questions to children, they must be targeted, and they can't repeat a question, which will make students feel tired of listening. Over time, the teacher's questions will lose their validity. Only refined classroom language can realize the effectiveness of teaching.
Fourth, cultivate children's ability to ask questions.
A great man once said: It is often more important to ask a question than to solve it. ? In mathematics teaching of lower grades in primary schools, cultivating students' questioning ability plays an active role in developing students' intelligence and thinking in quality education. Usually, asking questions by students themselves is a more demanding training.
1, cultivate students' questioning ability.
As a math teacher, we should know that problem consciousness is an important part of math training. Therefore, it is one of the responsibilities of mathematics teaching to cultivate students' learning habits and ability to dare to ask questions and be good at asking questions in class. As math teachers, we should carefully create opportunities to ask questions in class, and also consider making students really think about problems, put forward valuable math questions around the reality of life or find out what they don't understand. If this period of time can be effectively used in class, teachers can consciously train students in teaching and put forward exemplary questions to students as students. Over time, students' ability to ask questions has also been improved, and students' ability to actively think and solve problems has also been cultivated accordingly.
2、? Kind? Students ask and answer questions.
In the period when students try to ask questions, no matter what kind of questions the children ask and whether the questions they ask are feasible, teachers should give their children timely affirmation and encouragement as long as they think of their own problems, so that they are no longer afraid to ask questions. After taking the first step, I believe that children will become more confident. For problems with original opinions, our teachers should also point out the value of children's questions in time and then guide them to learn how to think deeply. Only in this way can children gain something from asking questions. Will be closer and closer to the problem that our teacher wants.
In practice, teachers should combine the reality and really improve the quality of classroom teaching.
3. Junior high school students' thinking in images is absolutely dominant. Therefore, how to improve quality and increase efficiency in a class is worth discussing. Junior high school students are lively and active. If we want them to learn mathematics well, we must pay attention to cultivating their interest in learning mathematics, and then make use of the situation to cultivate their good habits of consciously learning and positive thinking. Then, if we can improve students' interest in learning mathematics, we can give full play to the benefits of the classroom. This paper focuses on improving junior high school students' interest in learning mathematics from three aspects: cultivating good classroom study habits, diversifying and flexibly using intuitive teaching AIDS and diversifying classroom practice forms.

Junior high school students' thinking in images is absolutely dominant. Therefore, how to improve quality and increase efficiency in a class is worth discussing. Junior high school students are lively and active. If we want them to learn mathematics well, we must pay attention to cultivating their interest in learning mathematics, and then make use of the situation to cultivate their good habits of consciously learning and positive thinking. So how can we improve students' interest in learning mathematics and give full play to the benefits of the classroom? In practice teaching, I think we should start from the following aspects.
First, cultivate good classroom study habits.
Cultivating students' serious and responsible learning attitude and good study habits is an important condition for improving classroom efficiency and grades. The formation of habits requires us to start from the usual and start from the nuances.
1, fully prepare lessons.
At the beginning of school, we should emphasize the importance of preparation before class, bring textbooks and school supplies, put them in order, form neat and good habits, sit correctly, and make full preparations for entering the learning state.
2. Strengthen regular classroom training.
Junior students are lively and active by nature, so it is difficult to maintain lasting interest and easy to divert attention. Therefore, it is necessary to strengthen the training of classroom routines according to their psychological characteristics and strive to improve classroom efficiency. The cultivation of ability and habit should be reflected in all aspects of teaching;
(1) Require correct sitting posture, correct pen holding posture, and keep your eyes away from textbooks and exercise books; (2) Pay attention to the lecture in class, speak enthusiastically to the teacher's questions, and answer the questions loudly and clearly; (3) The homework should be completed in time, with correct handwriting, standardized writing and neat exercise books. Teachers should have enough patience and perseverance to help students develop good study habits. Over time, students get used to this learning procedure, concentrate, and naturally improve their learning efficiency. If teachers insist on students' vivid, lively and automatic development, the quality of all students will be improved, thus greatly promoting the development of education and teaching.
Second, the diversification and flexible use of visual AIDS can enrich the accumulation.
Visual teaching AIDS are important teaching methods in primary schools, especially in lower grades. They can turn abstraction into concreteness, attract students' attention, improve students' understanding ability and improve classroom efficiency. Because junior students have poor abstract thinking ability and strong curiosity, they have no intention to pay attention to occupy an important position, and anything new is easy to arouse their interest. In order to focus their interest and attention on learning effectively, we should give full play to the role of intuitive teaching AIDS. For example, when teaching mathematics, you can design colorful flowers, cute animals and other pictures as teaching AIDS, and you can also have a variety of teaching AIDS. Such as: square, bar, bitmap, beads, disks, squares, triangles, etc. So as to introduce students into novel and wonderful teaching situations at the beginning of the class, stimulate students' strong desire for knowledge, and make students firmly grasp what they have learned. In teaching, let students actively participate in the actual operation and use their hands and brains, so that they can sum up the rules and deepen their impressions on the basis of full perception.
Third, there are various forms of classroom exercises.
Teaching knowledge is boring and difficult for primary school students to accept. On the basis of obtaining perceptual knowledge in classroom teaching, it will achieve good results in understanding by using various classroom exercises to consolidate. For example, when teaching the composition of "5", let students make a Pentagon, branches, stairs, etc. Match five matches and ask the students to say how many matches make up five, so as to have a deeper understanding of the composition and decomposition. Then consolidate it in time, use teachers and students to check the password and clap your hands. For example, the teacher takes three pictures first, the students take two pictures, and then the students say that three plus two equals five. Let the students master the composition of 5 skillfully. In the classroom consolidation exercise, you can also play the following games: finding friends, winning red flowers, sending letters, kitten fishing, finding mothers, etc., to stimulate students' interest and rich imagination and improve the classroom teaching effect.
