Humanism of humanistic spirit is humanism, which is the main trend of thought in the European Renaissance. It advocates academic research, freedom of thought and liberation of personality, and affirms that man is the center of the world. The humanistic spirit we are talking about now emphasizes the freedom and rights of personality, personal dignity and personal value. As far as its teaching content is concerned, mathematics teaching always pays attention to people, whether it is concept teaching, problem-solving teaching or mathematical thinking method teaching. As M Klein said: "In the broadest sense, mathematics is a spirit, a rational spirit." Stiffness and simplicity are the basic scientific attitudes of mathematicians. Mathematics learning can get rid of impetuousness and purify people's souls. The way of thinking and the spirit of mathematics can help people develop a meticulous and organized way of thinking, which is helpful to cultivate students' meticulous work attitude, professionalism and strong sense of social responsibility. Honesty and truth-seeking are the essential characteristics of mathematical humanistic spirit. The accuracy of mathematical language makes the conclusion in mathematics not ambiguous. Diligence and self-improvement are the personality characteristics of endless exploration of mathematical truth. In the process of mathematics, we often encounter many difficulties. Through unremitting efforts, we can understand the true meaning of mathematics and cultivate students' tenacious will and exploration spirit. Pioneering and innovation are the basic qualities of modern science and humanities. Modern society needs more and more creative talents, and the process of mathematics learning is essentially a re-creation process. The exploration of theorems, conclusions and problem-solving methods in mathematics requires students to have innovative thinking and pioneering spirit. It is through this process of mathematical activities that students' pioneering and innovative spirit is cultivated. Mathematics teaching has a unique humanistic spirit, which constitutes the main content of mathematics teaching. 2. Humanistic spirit and the cultivation of students' quality.
Due to the long-term over-emphasis on groups, people's personality, values, rights and dignity have been ignored, and the oppression and distortion of human nature that has existed for a long time in China feudal society has not been eradicated. As a kind of capital, "human" has always been neglected. However, with the development of the times and the progress of society, it is unimaginable that our nation will be revitalized and our country will be strong without high-quality people with independent personality, independent mind and innovative spirit. Therefore, in the reform and opening up in recent years, the society is more and more aware of the importance of humanistic quality, and more and more shows the requirements for humanistic spirit. It is very timely and necessary to add healthy personality, sound personality and literati quality to mathematics curriculum.
The humanistic spirit of teaching content in mathematics teaching provides conditions for the cultivation of students' humanistic quality. Therefore, in mathematics teaching, teachers should flexibly adopt various teaching methods, take students as the main body, respect students, give full play to their initiative to explore, and let students feel, appreciate and create the beauty of mathematics, which is of great significance to stimulate students' desire to learn mathematics, optimize their quality structure, cultivate their creativity, thus improving their problem-solving level and cultivating their literati quality.
