Special teaching tool of economics

Technical Field

The utility model relates to a teaching technical field, concretely relates to special teaching tool of economics.

Background

Economics is the theory of economic development law, which is the law of researching human economic activities, namely the law of creating, transforming and realizing values, and is divided into two major types of political economics and scientific economics, the core idea of economics is the optimal allocation and optimal regeneration of resources, and the development of economics is divided into two major branches, namely micro-economics and macro-economics. The economics originates from the ancient Chinese economic thought, and the early economics represented by Greek color noun and Asia Riosdord, and through the development of economic scientists such as Adam Si Mi, Marx, Kaiens, Chinese economics and the like, the economics gradually develop from political economics to scientific economics, and the theoretical system and the actual application of the economics are continuously improved.

With the continuous development of society, the rapid progress of the data era and the gradual popularization of economic knowledge, the economics becomes one of the indispensable subjects of the university of financial major in the modern times, and teaching auxiliary tools for economic teaching sold on the market at present are various in types and different in styles, but have some defects to influence the use. In order to more intuitively and vividly show teaching information to students, files such as icons and pictures are often needed to assist teaching, the common method is to fix the icon and picture data on a blackboard through a clip for showing, the color system of the blackboard is dark, the students at the back cannot see the data clearly for learning, and meanwhile, real-time demonstration and example operation are often needed to be carried out on some form data in the teaching process; and teaching show effect is poor, does not set up auxiliary line and hole groove, appears easily when drawing the operation and draws inconvenient, the poor condition of effect of drawing, and the practicality is not high etc. leads to the user demand not high.

In order to solve the shortcomings in the market, the technology of teaching auxiliary tools for teaching is urgently needed to be improved, so that the teaching auxiliary tools can be more conveniently used for the economic teaching operation, help students to learn economic knowledge more clearly, and promote the continuous development of the economic teaching industry.

Therefore, it is necessary to design a simple teaching tool dedicated for economics.
