Entering the new curriculum today, writing mathematical papers as a learning method is gradually recognized by educators. So what is a math paper? The so-called math thesis refers to the short essays that students learn to write with the math content as the center in math learning, and its stylistic forms include math diary, math stories, math fairy tales and so on. Among them, math diary is a student who records his process, feelings and experience of learning and applying mathematics knowledge in the form of a diary; Mathematical fairy tales and mathematical stories refer to students' integrating their mathematical knowledge into the framework of stories and fairy tales according to their own understanding, thus forming a complete plot. 1. Cultivating students' mathematical reading habits refers to a learning activity that takes mathematical problems or related materials as the center, takes mathematical thinking as the foundation and link, and uses mathematical methods and concepts to know, understand, absorb knowledge and feel mathematical culture. At first, we found some excellent student diaries from the Internet and newspapers, so that students could read them, understand the choice of format and content of math diary, and stimulate their writing enthusiasm. Later, combined with school reading activities, students were organized to recommend excellent mathematics popular science books to each other. For example, mathematics in life, 100,000 Why's (math volume) and math microphone, and at the same time, colorful reading exhibition activities are carried out: colorful math handwritten newspapers written by students, valuable math scrapbooks and rich blackboard newspapers, which lead students into the world of mathematics and experience the charm of mathematics in reading. Stimulate students' writing enthusiasm. 2. Improving students' ability to reflect on mathematical papers is one of the important ways for students to evaluate themselves. Reflective papers can reflect on the advantages and disadvantages of the methods used to solve a problem according to their own math homework or test papers and classroom performance, know themselves and sort out related problems, thus laying a good foundation for continuing to learn math with confidence. This will help students learn from each other's strong points, improve their mathematical communication ability and enhance their self-confidence. In the long run, students should form the habit of self-reflection, improve the cognitive level of mathematics learning and enhance their ability of self-reflection. 3. Guide students to accumulate papers. Mathematics papers should not be satisfied with the diary of mathematical reflection, but should broaden their horizons. Teachers should make full use of students' existing life experience, guide students to apply what they have learned and realize the application value of mathematics in real life. At first, students didn't understand how to integrate mathematical knowledge and mathematical problems into stories and how to observe mathematical knowledge in life. The teacher should consider the problem from the students' point of view, write a model essay, read it to the students, and take the students to analyze: where is the mathematical knowledge applied? How to apply? What other mathematical knowledge can be applied and what storylines can be continued? Students imitate and practice writing mathematics papers, and gradually form the habit of observing life from the perspective of mathematics, which has accumulated rich perceptual experience for mathematics learning. In the investigation activities for writing mathematical papers, students' awareness of economic and environmental protection and strong sense of social responsibility are also cultivated. 4. Organize students to actively participate in the competition and contribute. Suhomlinski said: In people's hearts, there is a deep-rooted need to be a discoverer, a researcher and a winner. This demand is especially strong in children's spiritual world. Writing mathematics papers can help students at different levels to develop, let each student experience the happiness and success of mathematics learning and communication, and stimulate their enthusiasm for learning mathematics. We are delighted to find that letting students write math papers well has improved students' understanding that mathematics comes from life, stimulated students' enthusiasm for being close to mathematics, and experienced the fun of mathematics and life together, which is far more vivid and profound than learning mathematics from books, thus effectively promoting students' mathematics learning and promoting the development of their comprehensive quality.
