The first is the basic experiment. Focusing on the basic content of mathematics, students can make full use of the numerical function and graphic function of computers and software, show basic concepts and conclusions, and experience how to discover, summarize and apply mathematical laws. The second is applied experiment, which diverges from mathematics to marginal disciplines, involving knowledge related to mathematical modeling, such as numerical methods, mathematical statistics, graph theory and combination, differential equations, operational research, optimization and so on. Teachers introduce the main ideas, ask questions and tasks, and let students try to discover and summarize the rules by themselves and observing the experimental results.
