Piaget, a famous educator, said: "All mental work depends on interest." The success of education depends largely on whether students are interested in learning. Interest is not innate, but gradually cultivated in study and life, which is plastic. Therefore, in mathematics teaching, we should cultivate students' interest in learning, fully mobilize students' initiative and enthusiasm in learning, and change "I want to learn" into "I want to learn". So, how to cultivate interest? Let's talk about some superficial views on personal experience: First, care for students and cultivate their interest in learning mathematics. Suhomlinski said: "The whole mystery of educational skills lies in how to care for students." As a math teacher, due to the characteristics of the subject, students are often given a rigid and severe impression. If he always keeps a straight face in teaching, the classroom atmosphere will be tense and the psychological distance between teachers and students will be far away. In this way, students will have unnecessary psychological burden in the learning process. Over time, students will have rebellious psychology, thus losing interest in learning mathematics. Therefore, in the process of education and teaching, teachers should devote great enthusiasm, talk with students more, understand their ideological trends, and if possible, often carry out some collective activities with students to cultivate affinity, so that students can like this teacher and then like the course of mathematics. We should cherish students, respect their labor, solicit their opinions, try our best to meet their psychological needs in learning, and let them feel that they are valued and cared for, thus shortening the psychological distance between teachers and students. Especially for some underachievers, teachers should be persuasive and pay special attention to protecting their self-esteem. We should always encourage students with praise and rewards, so that they can change from being afraid of taking math classes to loving math classes and have a strong interest in learning math. Caring for students is the premise of mathematics teaching and the key to making students interested in mathematics. Only by injecting teachers' emotions into mathematics teaching and stimulating students' emotions in learning mathematics can students learn mathematics more actively. Second, experience the joy of success and cultivate students' interest in learning mathematics. "The joy of success is a huge emotional force that can urge young people to learn knowledge well. Without this power, any ingenious emotional measures in education will be of no help. " Psychological research shows that the generation and maintenance of interest depends on success. Students' interest in learning is always closely related to the joy of success. Students can understand a lesson, master a mathematical method, solve a mathematical problem, get good grades in the exam, and get encouragement and appreciation from teachers at ordinary times, which can make students experience the joy of success from these "successes" and stimulate higher learning enthusiasm. On the contrary, if students fail repeatedly in their studies, don't understand in class and can't do problems, they will gradually lose their interest and confidence in learning mathematics. In the process of education and teaching, teachers should be good at capturing every bright spot in students. When students succeed, giving correct evaluation and praise in time can improve students' interest in learning mathematics and stimulate their desire and motivation to learn mathematics better. Starting from the reality of students, we should design and create opportunities for competition and success, so that students at different levels can "jump and reach" according to the slope of the problem, thus enhancing their confidence in learning mathematics well. We should face all students, pay attention to teaching students in accordance with their aptitude, and let "success" approach every student. We should adhere to the principle of "shallow but not deep, fine but not extensive, slow but not fast", concentrate on the key and difficult points, and try our best to solve the difficulties in each class as soon as possible. According to the characteristics of mathematics itself, students are required to be stratified, especially for poor students, and more opportunities for their success in learning should be created to make them interested in mathematics and enhance their confidence. Third, create problem situations to cultivate students' interest in learning mathematics. One of the psychological characteristics of middle school students is their strong curiosity and thirst for knowledge. Strong curiosity can arouse students' strong interest in learning, and strong interest can arouse students' strong thirst for knowledge. Paulia, a famous American mathematician, said: "In order to make learning fruitful, students should be interested in what they have learned and seek happiness in learning." Therefore, in mathematics teaching, students should not be taught mathematics knowledge according to the book, but should actively create teaching situations to inspire students' thinking. This can not only enliven the classroom atmosphere, concentrate students' attention, induce students' curiosity and learning motivation, but also enhance students' curiosity, give play to students' main role and generate interest in learning mathematics. Of course, mathematics teaching should create a mathematical situation that is conducive to cultivating students to understand mathematical concepts, ask questions, construct conjectures and form intellectual thinking; Provide enlightening materials and give students the necessary time to ponder mathematical ideas; Attach importance to students' ideas, and encourage students to put forward personal opinions and exchange ideas. For example, when talking about "limit", teachers can analyze Zhuangzi's view that "one foot is enough, and half a day is inexhaustible" to enhance the classroom atmosphere and stimulate students' interest in learning limit. When learning "Geometric Series", tell the story that the ancient Indian prince "Silamu" encouraged the inventor of military chess, so that students can get into the topic while being fascinated by the story and happily bring into "interest-oriented learning". This method of setting suspense makes students more interested in what they have learned, and students can actively think and change their acceptance of knowledge from passive to active. Fourth, mathematics aesthetic education, cultivate students' interest in learning mathematics. People often say that where there is mathematics, there is beauty in mathematics. Mathematical beauty is different from natural beauty and artistic beauty, which is mainly manifested in inner beauty, logical beauty and rational beauty. Mathematical beauty is hidden beauty and profound beauty, and beauty lies in ideological content. To understand the beauty of mathematics, we must understand its inherent mathematical thought through "abstract and boring" symbols, formulas and theorems. Any intelligent activity is inseparable from human emotions, and the beauty of mathematics is the product of emotion merging into mathematical objects. Aesthetic education in mathematics is of positive significance for stimulating students' interest in learning, effectively mastering mathematics content, cultivating mathematics creativity and realizing mathematics value. But students' feelings and appreciation of mathematical beauty are different, which depends on teachers' excavation and display of beauty. In teaching, teachers should make full use of the beauty of mathematics in textbooks to stimulate students' learning motivation and interest, so that they can actively feel and pursue the beauty of mathematics. When asking questions, teachers should reveal the novelty or beauty of the questions to arouse students' curiosity in learning; When analyzing problems, let students feel the ingenuity and novelty of thinking methods and urge them to master them consciously; In a word, students should experience the beauty of harmony, unity and conciseness in mathematics. This can not only reduce the burden on students, but also make students feel the beauty of mathematical knowledge structure. "Everyone loves beauty." The gradual infiltration of "mathematical beauty" in mathematics can not only stimulate students' interest in learning, but also enlighten their thinking and broaden their horizons. Introduce the history of mathematics and cultivate students' interest in learning mathematics. Teaching practice shows that students have great interest in the history of mathematics and the stories of mathematicians. Therefore, I often consciously tell students some knowledge about the history of mathematics and stories about mathematicians in teaching, which greatly improves students' interest in learning mathematics. For example, when studying binomial theorem, I talked about "Yang Hui Triangle"; When studying Euler's formula, I introduced Euler (Euler completed more than 800 papers in his life, many of which were completed when he was blind and seriously ill). Make students realize that learning mathematics is very interesting and practical, clear away the psychological obstacles of "mystery" and "fear" and improve their interest in learning mathematics. "Interest is the best teacher." In education and teaching, we math teachers should pay attention to using various means and methods, cultivate and stimulate learning interest through various channels, and mobilize students' learning enthusiasm and initiative to the maximum extent. Only in this way can students learn mathematics well with strong interest and improve the teaching quality in a large area.
