The necessary condition for effective classroom teaching of Yu Yuhua in Southeast Middle School of Qidong City, Jiangsu Province is the active participation of students. There are many factors that affect the learning effect, and there are two factors that directly affect the effect. One is whether students participate in learning, and the other is at what level. Starting from reality, the degree of each student's participation in learning is definitely different, which is divided into three levels, namely emotional participation, cognitive participation and behavioral participation. Because of their different degrees of participation in learning, the quality of learning activities is also very different. Low learning efficiency and shallow learning participation, in which case students are in a passive state [1]; The best effect of education is that students are happy, active in thinking, actively exploring and actively constructing, which is a concrete interpretation of deep learning participation. First, expand the category of mathematics textbook resources 1. In formal logic, the expansion of knowledge connotation, "connotation" and "extension" are opposite, and the essential attribute of objective things reflected by the concept of knowledge is the definition of connotation. In order to deepen students' understanding and memory of knowledge, teachers need to explore and expand the connotation of knowledge according to the characteristics of knowledge content, so as to further strengthen the clarity of concepts and improve their discrimination ability accordingly; On the other hand, the knowledge learning method that only pays attention to the form is bound to lack the degree of exploring the essence, so it no longer pays attention to the extension of knowledge connotation. Students' thinking will become narrower and narrower, and their thinking in the learning process will be poor, so they can't get rid of the partial ambiguity and confusion, and even make repeated mistakes. 2. The thinking process of moderately expanding the mathematical thinking method is the thinking method. There are many classifications of mathematical thoughts, among which reduction and transformation, function and equation, combination of numbers and shapes, classified discussion and so on all belong to mathematical thoughts; There are many mathematical methods, such as the combination of numbers and shapes, mathematical induction, undetermined coefficient method, collocation method, method of substitution, coordinate method, parameter method and so on. "Mathematics teaching should not only teach students mathematical knowledge, but also reveal the thinking process of acquiring knowledge." This theory is clearly put forward in the mathematics curriculum standard. Accelerating and optimizing the process of solving problems can only be realized after combining mathematical ideas and methods. It can achieve the effect of knowing all the questions in advance and mastering all the same kind, and students' mathematical literacy will certainly be improved in an all-round way. 3. Tao Xingzhi, an educator who expands the ability of life application, mentioned the theoretical viewpoint that "education should be life-oriented". In this sentence, education and life are inseparable, and so should mathematics education. The purpose of mathematics education is to master knowledge, improve ability and serve the society. The teaching process should include common phenomena in life to explain the laws of mathematics, which will help mathematics enter every student's life [2]. When mathematics theory is closely combined with life practice, students can consciously apply mathematics to every detail of life, and it will become relatively easy to master what they have learned, thus realizing the value of mathematics learning in life. The classified queries of periodical articles are all in the periodical database. The second is related to other disciplines. Integrating teaching resources Teachers should explore curriculum resources according to the content of teaching materials and determine the teaching objectives of this course. No discipline exists in isolation, and mathematics is closely related to other disciplines, so the integration and development of mathematics curriculum resources should also be related to the resources of other disciplines. Use the resources of other disciplines to enrich mathematical resources and expand mathematical knowledge. It helps students to learn mathematical knowledge, master mathematical laws and understand mathematical concepts. To improve students' learning enthusiasm, deepen their knowledge, improve their flexible application ability and broaden their horizons. For example, the current Diaoyu Islands issue has aroused people's thinking about the military, political and economic capabilities of China and Japan. In the teaching process, math teachers can take the Diaoyu Islands issue as an opportunity, take the military and economic strength of the two countries as an example, and through the comparison and study of mathematical methods, let students think about problems themselves, learn how to analyze problems with mathematical methods, deepen students' understanding of mathematics, stimulate students' patriotic feelings, and urge students to think deeply about problems instead of acting impulsively. In short, teaching resources can be drawn from many aspects. Teachers should integrate all available resources, develop students' thinking, enrich mathematics teaching content, broaden students' horizons, improve students' comprehensive skills and literacy, and let students feel the value and significance of mathematics [3]. Third, integrate effective teaching resources and stimulate students to participate in classroom inquiry. 1. Study teaching objects and tap students' curriculum resources. (1) Fully consider the correlation between teaching objectives and students' characteristics, and use teaching methods flexibly. (2) Use the communication between students to tap the resources among students. 2. Stimulate students' emotions, mobilize students' enthusiasm, and tap students' emotional resources. (1) Help students in life and establish a harmonious relationship between teachers and students. (2) Often suggesting the ideal future education. (3) In class, express feelings and convey spirit. Express recognition and encouragement to students and stimulate their thirst for knowledge. 3. Teachers fully prepare lessons and tap all effective teaching resources. (1) Help students in both life and study, promote their all-round development and raise their awareness of autonomous learning. (2) Comprehensively consider the teaching objectives, teaching requirements and students' actual situation, and integrate effective and high-quality resources to adapt to the teaching content and methods. (3) Actively participate in the exchange meeting between teachers, constantly improve their teaching methods and enrich their teaching resources. Four. Conclusion The development and utilization of curriculum resources is an important link in implementing curriculum plan and achieving curriculum objectives. To implement the new senior high school mathematics curriculum, we should not only make full use of and expand the existing curriculum resources, but also actively research, develop and improve some urgently needed curriculum resources to ensure the smooth implementation of the new senior high school mathematics curriculum. Teachers are the most important curriculum resources, and the identification, development, accumulation and utilization of curriculum resources are determined by teachers. Therefore, the traditional teaching mode must rely on teachers to change and innovate ideas, actively promote inquiry teaching and strive to develop mathematics teaching resources. [2] Zhu Zhu.
