数学是一门重要的学科，随着数学的发展，它过去的发展过程越来越受到学者的重视，当数学史受到重视，就会有许多的数学教育家开始研究数学史与数学教育之间的关系和该如何在数学课堂中融入数学史。在学者们的研究中发现，数学史的融入是十分重要和有意义价值的，这有利于激发学生的学习兴趣；有利于学生树立学习数学的自信心，培养勇于面对困难的精神；有利于提高学生的数学素养、科学精神和创新意识；有利于培养学生的爱国情怀等。但因为我国的数学教育现状仍然是以应试教育为主，在数学史融入课堂时，往往会出现一些困难。因此，本文将通过研究调查的方式，发现了在融入时可能会出现的困难，例如老师的数学史知识缺乏、课时紧张和学生抗拒等，分析为什么会出现这种问题，尝试解决这些问题，并以勾股定理的证明这一章节为例，把勾股定理证明的发展过程融入课堂，整理出一份教学过程的设计，从而清楚了解怎么去融入数学课堂，并且促进了学生的发展和数学未来的发展。

Mathematics is an important subject. With the development of mathematics, its past development process has been paid more and more attention by scholars. When the history of mathematics is valued, many mathematics educators will begin to study the relationship between the history of mathematics and mathematics education. relationship and how to incorporate the history of mathematics in the mathematics classroom. In the research of scholars, it is found that the integration of mathematics history is very important and meaningful, which is conducive to stimulating students' interest in learning; it is conducive to establishing self-confidence in learning mathematics and cultivating the spirit of courage to face difficulties; it is conducive to Improve students' mathematical literacy, scientific spirit and innovative consciousness; help to cultivate students' patriotism and so on. However, because the current situation of mathematics education in our country is still dominated by exam-oriented education, some difficulties often arise when the history of mathematics is integrated into the classroom. Therefore, this paper will find out the difficulties that may occur during integration through research and investigation, such as the lack of teachers' knowledge of mathematics history, the tension in class time, and the resistance of students, etc., analyze why such problems occur, try to solve these problems, and Taking the chapter of the proof of the Pythagorean theorem as an example, the development process of the proof of the Pythagorean theorem is integrated into the classroom, and a design of the teaching process is sorted out, so as to clearly understand how to integrate into the mathematics classroom, and promote the development of students and the development of mathematics in the future.
