A professor once pointed out that a positive, harmonious, democratic, equal and joyful classroom atmosphere is the "sunshine, air and water" for the growth and development of students' potential, creativity and positive and healthy attitude towards life, which requires teachers to create an open teaching environment for students. Make classroom teaching integrate students' emotion, experience, thinking and innovation, and make children's healthy personality develop harmoniously and comprehensively. Let children reflect on the success of mathematics application in the beautiful space of guessing, imagining and exploring problems. For example, in the lesson "Angle and Right Angle", I designed it like this: Find the right angle in the picture below. After the students reported that there was no right angle in the circle, the teacher took the opportunity to guide: "Can you make a right angle in the circle?" At this time, the students took out the prepared circular pieces of paper, and methods such as "folding" and "drawing" came to the fore. Students are full of enthusiasm, even students with learning difficulties are willing to discover and explore, and their faces are filled with satisfaction and happiness of success. It gives students the opportunity to express themselves, stimulates their potential, and the natural process of teaching is completed.
2. Create game situations to improve students' interest in learning.
According to the characteristics of mathematics and the age of primary school students, we should set up game situations, put new knowledge into game activities, make students eager for new knowledge through games, make students' attention in a highly concentrated state, acquire knowledge through games and improve their interest in learning. For example, in class training, organize a 60-second quiz game. I prepare several groups of oral math questions, divide the class into several groups, and choose three students as representatives in each group. Then the teacher asks questions, so that each group of students can answer first, and the winner is the one who scores more, or a small red flag is awarded for each correct answer, and the winner is the one who scores more. In the game, students pay close attention and unconsciously learn a lot of useful knowledge, which effectively improves students' interest in learning.
3. Strengthen hands-on operation to stimulate students' interest in learning.
"Play" is a child's nature. Suhomlinski once pointed out: "If teachers don't try to make students feel high, excited and eager to impart knowledge, mental work without emotion will bring fatigue. Without exultation and interest in learning, learning will become a burden. " In primary school mathematics classroom teaching, teachers can organize some students' activities, measure, demonstrate or operate some practical problems by themselves, so that students can get learning results through hands-on thinking, which can not only consolidate and flexibly use what they have learned, but also improve their operating ability and cultivate their innovative spirit. For example, when talking about "axisymmetric graphics", I ask students to prepare rectangular, square, circular, parallelogram and several triangular pieces of paper in advance. Ask the students to try to fold each figure in half, so that the figures overlap completely after being folded in half. After the operation, students found that some graphics can completely overlap, and some graphics can't completely overlap. Through hands-on operation, students can find and solve problems themselves, and effectively arouse their interest in learning.
4. Consolidate exercises and improve interest in learning
Consolidating the practical stage is an important means to help students master new knowledge, form skills, develop intelligence and cultivate ability. Psychological experiments have proved that after nearly 30 minutes of intense study, students' attention has passed the best period. At this time, students are easy to get tired and have low interest in learning. In order to maintain a good learning state and improve students' interest in practice, I not only pay attention to the purpose, typicality and pertinence of practice, but also pay special attention to the design of practice forms to make practice interesting. In practice, it is mainly to ask some thoughtful questions or create a situation for students to practice in a relaxed and pleasant atmosphere to achieve our predetermined teaching goals. For example, when teaching the content of "divisor and multiple", I designed a game of "leave the classroom with your brain" at the end of the class: students whose number is exactly your student number can leave the classroom for activities. Then the teacher said "divisible number by 3, multiple of 2, divisor of 30 …" until all the students left the classroom. Through this game, students have consolidated the teaching content of this class, with strong interest and active classroom atmosphere.
Starting from the practical problems in life, cultivate students' interest in learning.
Connecting with the reality of life means paying attention to the practicality of mathematics, making mathematics close to life and highlighting the application ability from solving practical problems. Therefore, make full use of this feature in mathematics teaching, try to connect with reality and solve practical problems with examples and knowledge around you. Let mathematics go to life, let students experience mathematics in life, let students understand that mathematics is not mysterious, and mathematics is around us, reflecting the practicality of mathematics. For example, when teaching the understanding of RMB, let students and parents go shopping in the supermarket before class, realize emotionally that shopping needs RMB, and remember the price of the items they buy. Let the students talk about how to shop in class to pave the way for learning RMB. In the classroom, students are also allowed to buy different kinds of goods with different prices through simulation, so that students can perceive the commodity function of RMB in the process of simple payment, calculation and currency exchange, realize that RMB is everywhere in life, and everyone can learn valuable mathematics to realize the connection between mathematics and life. In this way, students' learning enthusiasm will be mobilized.
Teaching practice shows that interest is the secret of teaching success. "Promoting learning with interest" can not only fully mobilize students' learning enthusiasm, make them think happily, act happily and learn actively, but also help to cultivate students' spirit of bold exploration and innovation.
