Because of the important position and function of mathematics, every student has the desire to learn mathematics, but why are some people easy to learn and others have great difficulty? Is there any magic weapon to learn math well? I think there is, and that is interest. Einstein said that interests and hobbies are the best teachers. With interest, you have the motivation and direction to learn. So how to cultivate students' interest in learning? I have been teaching for many years. Based on the teaching theory of pedagogy and psychology and my teaching experience, I think mathematics teaching should pay attention to interest teaching. According to the psychological characteristics of middle school students, their attention in each class is not consistent. Attention is usually concentrated for more than 20 minutes. If the teacher tells the story in a straightforward way and there is no climax, the students will sound bored or even bored. So how can we improve the quality of classroom teaching? I think it is very important to grasp students' interest in learning in classroom teaching, especially in math class, which is abstract and logical, so it is decided that math teaching should be interesting. In the teaching process, I pay attention to interest teaching from the following aspects:
First, the clever use of bedding teaching in mathematics class makes students have the enthusiasm to accept new knowledge.
The so-called foreshadowing teaching refers to the careful design of review questions before teaching new lessons, so that students can naturally transition to new knowledge in the review process. Mature teaching conforms to the principle of gradual progress and the law of knowledge transfer, so that students can further deepen their understanding of what they have learned on the basis of existing knowledge and naturally acquire new knowledge. Mathematical knowledge is very logical and systematic. Generally speaking, new knowledge is the extension, development and synthesis of old knowledge. For example, when I was talking about real numbers and number axes, I carefully designed a review question: What is rational number? Irrational numbers such as л are derived from rational numbers, so that students can learn irrational numbers and real numbers on the basis of rational numbers, and link old and new knowledge, so that it is not difficult to make new lessons new, which conforms to the law of students' understanding from known to unknown, facilitates students' understanding of new knowledge, cultivates students' interest in learning, and meets the requirements of modern teaching concepts.
Second, skillfully set the lead to stimulate students' enthusiasm for learning.
Teachers should try their best to design a novel lead in each class, which is a prerequisite for a good class. Carefully designed lead, like a stone thrown into calm water, can keep students' brains in the most exciting state.
There are various forms of lead-in, such as: ① lead-in, combining with the content of this lesson, asking students relevant questions, stimulating students' desire for knowledge, making them enter a positive thinking state, and under the action of this motivation, making them actively participate in learning, thus activating the classroom atmosphere; (2) Scene introduction, there are many teaching methods, such as using audio-visual means to design some beautiful animations, vivid examples can attract students' attention and let students enter the learning state. ③ Intuitive import. When teachers teach some theorems and define formulas, they often use exercises to introduce them. I think it is better to import directly. For example, when talking about rational numbers, you can directly show some rational numbers, and then say that numbers like this are rational numbers, which will arouse students' curiosity to learn it and thus become interested in it; ④ Introduce examples from daily life. When I was talking about the definition of vertical diameter, the introduction was designed as follows: We learned this article by Zhao Zhouqiao in Chinese class. Zhao Zhouqiao was built in the Sui Dynasty in China, with a history of 1300 years. Although it has experienced ups and downs, it is still as strong as ever. It embodies the wisdom of the ancient working people. Zhao Zhouqiao's arch is round. If the camber and span of the bridge are known, how to find the radius? This uses the content of the vertical diameter theorem that we learned in this lesson. This design of the lead leaves students with suspense, and students are curious and curious, which immediately attracts their attention; ⑤ Introduce from social phenomena familiar to students; ⑥ Import by comparing examples; ⑦ Deliberately looking for the wrong example and introducing the result from negation; Mastering the methods of introducing contextual review can stimulate students' interest in learning.
Third, in teaching new classes, we should pay attention to the interest of language and the flexibility of teaching methods in order to arouse students' learning enthusiasm.
1. Teachers' humorous language can stimulate students' learning enthusiasm and attract their attention.
2. Flexible teaching methods can also stimulate students' interest in learning.
For example, when I was talking about the bisection theorem of parallel lines, I used the guided discovery method, and found the conclusion through operation in three teaching links:
Operation: Let the students do it themselves.
(1) Give everyone a piece of exercise paper and another piece of hard paper.
(2) Let the students draw a straight line on the exercise paper at will, and measure the length of the line segment cut by the horizontal grid with a scale.
Discovery: Let students discover the rules.
Conclusion: The bisection theorem of parallel lines is derived.
By letting students arouse their interest in learning, I pay attention to the cognitive law of the development from perceptual knowledge to rational knowledge, avoid straightforward narration, and let students remember the content of this lesson deeply. At the same time, I also pay attention to intuitive teaching and adopt modern teaching methods to cultivate students' interest in learning.
Fourth, carefully design classroom training to stimulate students' interest in learning.
Classroom training is an important part of teaching, so when designing training, teachers should have various forms, moderate questions, clear levels, from easy to difficult, and follow the teaching principle of teaching students in accordance with their aptitude, so that all kinds of students can get their place through classroom teaching and achieve the best classroom effect. For example, in my teaching, I use games and red flags to develop students' intelligence, so that students have a sense of participation and competition, increase their interest in learning, and develop students' intellectual and non-intellectual factors. When I was teaching the knowledge of quadratic roots, factorization and idempotency, I adopted the above methods and achieved good results. Correct the mistakes in students' exercises in time, and appropriate guidance and evaluation can also stimulate students' interest, especially for students with learning difficulties. We should discover their advantages in time, encourage them, establish their self-confidence, and urge them to think positively, fully affirm the students' bright spots, and urge them to think independently, have unique opinions and have innovative spirit.
Fifth, through the summary of this lesson, arouse students' learning enthusiasm.
Sixth, create intriguing conclusions to arouse students' enthusiasm for learning.
A simple, concise and appropriate conclusion will make the finishing point for the understanding of the whole class. If the conclusion is thought-provoking, it can greatly stimulate students' interest in learning. For example, when I was teaching the image and properties of quadratic function, the conclusion was designed like this: the image of quadratic function is like this, so what is its property? Continue to study in the next class, so that students have a strong interest in the next class.
Seven, through homework, cultivate students' enthusiasm for learning.
In order to better consolidate the learned mathematics knowledge, cultivate students' ability to solve practical problems and enhance students' interest in learning mathematics, homework after class should start with reducing students' learning burden, but at the same time, students should be able to digest, understand and consolidate the knowledge in each class. I often use the method of hierarchical training to leave students with different homework questions, so that students of all levels and types can develop, pay attention to the context of knowledge and develop students' non-intellectual factors.
Eight, blackboard design, through blackboard design to cultivate students' enthusiasm for learning.
Blackboard design plays an important role in classroom teaching. Writing on the blackboard should follow the principles of conciseness, standardization, beautiful handwriting, systematic content and prominent key and difficult points. Giving people a beautiful feeling, teachers carefully design blackboard books, which is conducive to developing students' intelligence, cultivating students' ability, mobilizing students' interest and forming good study habits.
In short, in classroom teaching, I pay attention to arouse the learning enthusiasm of all kinds of students, carefully design every link of classroom teaching, arouse students' emotional resonance, create a relaxed, cheerful and positive classroom atmosphere for students, encourage students to think positively, conduct beneficial discussions, guide students to observe with their eyes, stimulate students to think with their brains, inspire students to express orally and organize students' operations, which shows that teachers are the organizations in the teaching process. Only in this way can we reach the state from knowledge to goodness and then to joy, thus improving the teaching effect.
