Teaching assisting device for mathematical probability class

Abstract

The invention belongs to the technical field of teaching apparatuses, and particularly discloses a teaching assisting device for a mathematical probability class. The teaching assisting device comprises an installing base, a first rotating rod, conical funnels, display modules, coin tossing assemblies, experiment standing columns and a knocking unit; the installing base is an L-shaped plate; the first rotating rod is rotationally connected on the installing base, the two conical funnels are symmetrically and fixedly connected to the two sides of the first rotating rod, and each conical funnelcomprises two conical plates and a side plate connected between the two conical plates; a first through hole is formed in the first rotating rod, and is communicated with the two conical funnels. It is only needed to rotate the first rotating rod, through cooperation between the conical funnels and the display modules, normal distribution experiments can be repeatedly conducted, students conveniently view the experiments multiple times, and understand the meaning of normal distribution, and operation is also easy and convenient during using; through cooperation of supporting plates, pushing rods, shifting plates and first spring pieces, multiple coins can be tossed one time, and the efficiency of a coin tossing experiment is improved.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to an auxiliary teaching equipment for mathematics probability class. Background technique [0002] Probability is a branch course in mathematics. In order to better demonstrate the theory of probability to students; traditional probability experiments are generally demonstrated by teachers by tossing coins multiple times or randomly throwing balls into multiple boxes. , but this method is very inconvenient to implement, low in efficiency, wastes the teacher's classroom time, and also consumes the teacher's physical energy. Contents of the invention [0003] In order to make up for the deficiencies in the prior art, a kind of auxiliary teaching equipment for mathematics probability class proposed by the present invention can carry out multiple probability experiments, and can intuitively show the experimental results to the audience, and is conducive to the research of ...
