At present, legal education in all walks of life is booming like mushrooms after rain. However, the school is a crowded place to persuade education. However, because junior high school students are in the stage of rapid physical and mental development, they have strong imitation and plasticity, which is the best time to form legal consciousness, cultivate noble moral sentiments and good behavior habits. Now the probability of students committing crimes is getting higher and higher. Therefore, it is of great significance and necessity to carry out legal education for junior high school students. At present, the phenomenon of school students violating discipline is prominent, and campus violence incidents occur from time to time. According to the information of radio and television media, juvenile delinquency is on the rise in recent years, which fully shows the urgency of improving junior high school students' legal awareness. Therefore, math teachers should make full use of math classes, take various forms, channels and flexible legal education according to students' reality, and improve students' legal awareness. In fact, mathematics originates from life, exists in life and is applied to life. The knowledge of mathematics also contains rich legal resources. The key is how to develop and use legal education resources and mathematics classroom teaching to achieve the purpose of education and teaching. As a math teacher, the author thinks that pure law education is too boring, and students may not like it. Under the premise of not increasing students' learning burden, it will achieve twice the result with half the effort to let appropriate legal knowledge penetrate into mathematics classroom. Today, crime is increasingly dominated by students, and this paper focuses on how to better carry out legal education in mathematics teaching. First, find the "breakthrough point" In order to infiltrate legal education in mathematics classroom, teachers should carefully study the teaching materials, fully tap the potential legal education elements in the teaching materials, find the breakthrough point and breakthrough point of legal knowledge, and naturally integrate legal knowledge into mathematics teaching. For example; Infiltrate Article 6, Article 12 and Article 14 of the Product Quality Law into the positive and negative numbers of section 1. 1 in the first chapter of grade seven. Infiltrate "Population and Family Planning Law" and "Land Management Law" into the scientific counting method in the first chapter 1.5.2 of grade seven; The measurement of the length of the fourth chapter in the first volume of the seventh grade, the first, third and fifth articles of the Metrology Law, etc. Second, skillfully create teaching situations to educate students in the legal system. In mathematics teaching, we should also pay attention to its strategies. We must not pretend to be the master, improve the consciousness of infiltration, grasp the feasibility of infiltration, and pay attention to the repeatability of infiltration. I believe that as long as students' ideological reality and knowledge acceptance ability are combined in teaching, the dual educational purposes of moral education and intellectual education can be achieved through dribs and drabs, organic infiltration and subtle influence. According to the content of the textbook, interspersed appropriately. For example, when talking about speed, traffic law can be infiltrated into teaching to tell students about the dangers of speeding and the penalties for speeding in traffic management regulations. Third, seize the opportunity to purify students' minds. In the colorful mathematics teaching activities, if teachers can properly grasp the methods and opportunities of legal education and use them flexibly, it will certainly get twice the result with half the effort to improve students' ideological consciousness and resist spiritual pollution. For example, after learning simple data sorting, I gave my students homework: after coming home from school, I investigated the number of garbage bags used by my family every day. By calculating the number of garbage bags used by a family in a month, combined with the impact of garbage bags on the environment, I talk about my own views. In this way, students not only master the relevant mathematical knowledge, but also infiltrate the environmental protection law into students, which can be described as killing two birds with one stone. Fourth, pay attention to the "infiltration" method. In the teaching process, teachers can use flexible and diverse teaching methods to subtly educate students on the legal system, such as research-based learning and cooperative learning. In mathematics, there are many rules and laws, and it won't work if the teacher teaches them orally. At this time, students can be guided to discuss, think and summarize together. This can continuously cultivate students' various abilities, and also cultivate students' ability of unity and cooperation. As far as teaching methods are concerned, we can adopt group cooperative learning. This learning method * * * enjoys the idea that students should be as responsible for others' learning as they are for their own learning, and students should study on the premise of benefiting themselves and others. In this situation, students will realize that there is an interdependent relationship between individual goals and group goals, and only when other members of the group succeed can they succeed. You can also let them form the habit of taking others' academic achievements seriously from an early age. Fifth, improve the literacy of educators. Students receive education at school and have the longest contact with teachers. Teachers' own image and a spirit embodied by teachers have a great and direct influence on students. Therefore, as a qualified middle school teacher, we should not only conscientiously do our job, study hard new educational concepts, deeply understand new educational concepts, and effectively improve the teaching level, but also list the Teachers Law, the Law on the Protection of Minors, the Education Law and other laws and regulations as compulsory contents, and pay attention to the formation of their own good quality, so as to cultivate qualified talents with legal concepts and legal awareness. Infiltrating legal education in mathematics teaching must organically combine teaching content with legal education. We can neither teach mathematics as a legal course, nor ignore the legal education factors contained in the teaching content. According to the characteristics of mathematics subject and the content of teaching materials, we should properly grasp the discretion in teaching and infiltrate it imperceptibly. For example, when we teach math games, we use situational teaching to teach students to abide by the rules of the game. Let the students know why to obey the law, how to obey the law and what is a crime. From this, I learned the legal common sense that laws must be obeyed, law enforcement must be strict, and violators must be prosecuted. In the colorful mathematics teaching activities, if teachers can properly grasp the methods and opportunities of legal education and use them flexibly, it will certainly get twice the result with half the effort to improve students' political and ideological consciousness and resist spiritual pollution. In a word, legal education cannot be solved overnight in a few classes. As teachers, in the colorful mathematics teaching activities, if teachers can properly and flexibly grasp the methods and opportunities of legal education, attach importance to students' peacetime education, focus on the overall situation, start from small things, and make legal education deep and detailed. In today's society, as a teacher, we should combine legal education with the teaching of various disciplines and infiltrate into the teaching of related disciplines. Explore some feasible ways to infiltrate moral education, organically combine imparting scientific knowledge with legal education, so as to enable students to develop in an all-round way and cultivate qualified talents for socialist education. Let's work together to create a pure and clean legal sky for the healthy growth of students and promote their healthy and happy growth.
