Mathematics probability experiment device for college teacher teaching

Abstract

The invention discloses a mathematics probability experiment device for college teacher teaching. The device comprises a rack, a mounting groove, a storage assembly, an experiment assembly, a transparent plate, grips, a supporting assembly, a fixed base and a counterweight plate, the supporting assembly is arranged on one side of the back of the rack. The bottom of the supporting assembly is connected with the fixed base. The mounting groove is formed in the end surface of the front end of the rack, the material storage assembly is arranged at the top of the inner side of the mounting groove,the experiment assembly is arranged in the center of the inner side of the mounting groove, the transparent plate is mounted on the outer side of the mounting groove, and grips are fixedly mounted inthe centers of the end surfaces of the two sides of the rack through screws; the mathematics probability experiment device for university teacher teaching is simple in structure and small in size; when the device is used, a normal distribution probability experiment can be carried out, and the experiment operation is simple; and meanwhile, good structural stability is achieved, the probabilistic small balls can be recycled and arranged, and the use convenience is greatly improved.

Description

technical field [0001] The invention relates to the field of teaching apparatus and equipment, in particular to a mathematical probability experiment device used by university teachers for teaching. Background technique [0002] Normal distribution, also known as "normal distribution", also known as Gaussian distribution, is a very important probability distribution in the fields of mathematics, physics and engineering, and has a significant influence in many aspects of statistics; university teachers are very important in mathematics teaching It is necessary to demonstrate the normal distribution to students; the experimental device in the prior art has simple structure, single function, and cumbersome operation; moreover, after the experiment is completed, it is inconvenient to store the balls. Therefore, it is necessary to design a teaching device for university teachers A mathematical probability experimental setup is necessary. Contents of the invention [0003] The ...
