The teaching goal should take curriculum reform as the core, subject research as the carrier, the all-round development of students and the continuous improvement of teachers' professional ability as the goal, and the improvement of classroom teaching efficiency, teaching quality and the reduction of students' academic burden as the basis.

Mathematics is a science that studies quantitative relations and spatial forms in the real world. In the long history of its emergence and development, it has always been closely related to various application problems. The characteristics of mathematics lie not only in the abstraction of concepts, the rigor of logic, the clarity of conclusions and the integrity of systems, but also in the universality of applications.

Mathematical technology:

With the rapid development of computer technology, the application of mathematics not only plays an increasingly important role in engineering technology, natural science and other fields, but also penetrates into new fields such as economy, management, finance, biology, medicine, environment, geology, population and transportation with unprecedented breadth and depth. The so-called mathematical technology has become an important part of modern high technology.

Mathematical model is a kind of simulation, which is an abstract and concise description of the essential attributes of practical topics with mathematical symbols, mathematical formulas, programs and graphics. It can not only explain some objective phenomena, but also predict the future development law, and also provide an optimal strategy or a better strategy in a sense for controlling the development of a phenomenon.
