Many math teachers think that moral education in middle school teaching is mainly about politics, history, Chinese and other class teachers and liberal arts teachers, and has nothing to do with science, especially math teachers. Under the influence of this concept, for a long time, in middle school teaching, we often only pay attention to the teaching of basic knowledge and skills, while ignoring moral education, which has caused a blank area of moral education to some extent. In fact, all primary and secondary school teachers should undertake the task of moral education, and math teachers are no exception. So how can we better infiltrate moral education in mathematics teaching?
First, the significance of moral education in mathematics teaching
The new curriculum standards put moral education in a very important position. The training objectives of the new curriculum guide us to make students have the spirit of patriotism and collectivism, love socialism, inherit the consciousness of socialist democracy and legal system, and abide by national laws and social ethics; Gradually form a correct world outlook and values; Have a sense of socialist responsibility, strive to serve the people, and make students become a new generation with ideals, morality, education and discipline. This fully shows the important position of moral education in the whole education and teaching, and the infiltration of moral education in the classroom is the main channel of moral education. Therefore, it is particularly important to pay attention to moral education in mathematics teaching, cultivate students' good personality and dialectical materialism, and carry out ideological and moral education.
Second, the specific methods of moral education in mathematics teaching
1. Educate them in patriotism through the history of mathematics and establish a scientific outlook on life.
The new curriculum standard points out: "Patriotism education should be placed in a prominent position in moral education, combined with imparting scientific and cultural knowledge, infiltrated into teaching materials and school activities, and strive to be lively. "In teaching, you can tell students the history of China's mathematics development in combination with the teaching content. From the ancient knot count to the medieval" Nine Chapters Arithmetic ",it is the earliest mathematical achievement; The ancient mathematicians in China began to study pi from Liu Hui in Wei and Jin Dynasties, and Zu Chongzhi's accurate calculation of pi was much earlier than that in Europe in the Southern and Northern Dynasties. Since modern times, Hua has made outstanding contributions in a wide range of mathematical fields, such as analytic number theory, matrix geometry, typical groups, automorphic function theory, multiple complex variable function theory, partial differential equations, high-dimensional numerical integration and so on. Because of Hua's great contribution, many theorems, lemmas, inequalities, operators and methods are named after him. Published nearly 300 monographs and academic papers. China also advocates the development of applied mathematics and computers according to the reality of China and the international trend. He personally went to 27 provinces and cities to promote the application of mathematical methods for 20 years and made great contributions to economic construction. By introducing the history of Chinese mathematics, we can make the classroom full of patriotic passion, stimulate students' strong national pride and curiosity, and implement moral education.
Mathematics class is by no means a simple knowledge transfer. I interspersed some mathematicians' stories in my teaching to stimulate students' desire for knowledge and make them have a strong interest in learning. For example, Chen Jingrun teacher Shen Yuan said: "The crown of natural science is mathematics, the crown of mathematics is number theory, and Goldbach conjecture is the jewel in the crown." Since then, Chen Jingrun has established the ideal of proving Goldbach's conjecture to win the pearl. The proper guidance of such cases makes students understand that in today's knowledge-based economy era, it is absolutely impossible for a person to survive and make a difference in society and become a useful talent for the modernization of the motherland without studying hard and mastering scientific knowledge, thus enabling students to establish their ambition to become talents and study hard for the prosperity of the nation.
2. Aesthetic education for students in mathematics teaching.
Beauty belongs not only to art, but also to mathematics. Mathematical graphics embody the external beauty of mathematics, while the rigorous harmony of abstract symbols, formula symbols, reasoning and argumentation and mathematical thinking mode is the internal beauty of mathematics. Since mathematics is beautiful, mathematics teaching should play its aesthetic function and become an important means of aesthetic education. Mathematics is a science that studies quantitative relations and spatial forms in real life. The objectively existing entity provides mathematics with extremely rich contents, which makes mathematics full of beauty: the concise beauty of mathematical language, the singular beauty of solving mathematical problems, the harmonious beauty of the whole mathematical system, and the similar beauty formed by similar phenomena between concrete content and form. For example, Yang Hui Triangle gives people a harmonious, symmetrical and symmetrical beauty.
3. Use mathematics classroom to educate students on dialectical materialism.
Engels pointed out: "Mathematics is a dialectical auxiliary tool and manifestation, and even elementary mathematics is full of contradictions." The idea of unity of opposites can be seen everywhere in the mathematical system. Mathematics is a very logical subject. Its emergence and development, like other things, strictly follow the laws of materialist dialectics. For example, from the generation, popularization and popularization of mathematical concepts, from the application of numbers, formulas, equations and functions, and the relationship between them, students can be educated in materialistic viewpoints such as things are constantly developing, things are interrelated, and theory comes from practice and acts on practice. From the transformation teaching of numbers and expressions, addition and subtraction, students can be educated from the materialistic point of view, and the two sides of contradiction can be transformed into each other under certain conditions. Plane geometry is a good textbook of materialist dialectics. For example, in quadrilateral teaching, quadrilateral can be transformed into trapezoid, parallelogram, rectangle, prism and square through the movement of its four sides and the change of its length, so as to educate students on dialectical materialism that things are constantly changing and developing in motion.
Mathematics education not only enables students to have a profound grasp of mathematics knowledge, but also realizes that things in the world are generally interrelated and transformed. We can not only observe the world from a static point of view, but also look at the surrounding things from a contradictory analysis point of view, so as to guide students to have a higher level of understanding of study life, cultivate students' ability to adapt to and transform the environment, optimize their psychological quality, and quietly inject dialectical materialism into students' hearts while fully demonstrating the magic and beauty of mathematics.
4. Cultivate students' strong will quality from mathematics teaching.
Because mathematics is a discipline with strict structure, systematicness and strong logic, in mathematics teaching, students can cultivate good study habits and strong ability through mathematical reasoning, meticulous interlocking, paying attention to problem-solving format, step arrangement, neat handwriting, cleanliness and beauty, trying to find reasonable and simple problem-solving methods, testing results, finding out the cause of mistakes, not afraid of difficulties, pursuing truth, and consciously making remedies and corrections.
