Abstract

The invention relates to a demonstration device for mathematics education, in particular to a device for probability calculation for mathematics education. The objective of the invention is to provide the demonstration device which achieves vivid demonstration, allows students to easily understand the probability and capable of improving working efficiency. In order to solve the technical problem, the demonstration device comprises a base plate, a support and the like. The support and a collection frame are installed on the top of the base plate in a bolted connection manner. The support is arranged on the left side of the collection frame. A top plate is arranged on the top of the right side face of the support in the horizontal plane in a bolted connection manner. A guidance device is arranged on the left side of the bottom of the top. According to the invention, the first motor is used for achieving driving, so a placing box is rotated so as to uniformly mix small balls in different colors, or by swinging a swing rod, the small balls in the different colors are mixed uniformly; the demonstration device is simple in operation and convenient to use; and effects of achieving vivid demonstration, allowing the students to easily understand the probability and improving working efficiency are achieved.

Description

technical field [0001] The invention relates to a demonstration device for mathematics education, in particular to a demonstration device for probability calculation used in mathematics education. Background technique [0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it is a kind of formal science. [0003] Mathematics education is the study of the practice and methods of teaching mathematics. Moreover, mathematics educators are concerned with the development of tools and research to facilitate this practice. Mathematics education is one of the subjects of intense debate in modern society. [0004] In the prior art, teachers demonstrate probability in mathematics education. The demonstration is not intuitive, making it difficult for students to understand and reducing learning efficiency. Therefore, it is urgent to develop a mathematics education that is intuitive in demonstra...
