Simulation demonstration teaching aid for mathematical probability statistics

Abstract

The invention discloses a simulation demonstration teaching aid for mathematical probability statistics, and relates to the technical field of mathematical teaching devices. The simulation demonstration teaching aid comprises a transparent box and iron coins, wherein one side of the bottom in the transparent box is fixedly connected with a transmitting box, a transmitting device is installed in the transmitting box, the middle of the side wall, close to the output end of the transmitting device, of the transmitting box is provided with a transmitting groove, baffles are arranged on two sides of the outer surface of the side wall, a transmitting position is arranged between the two baffles, the iron coins are placed at the transmitting position, the transmitting groove is positioned on oneside of the middle of the iron coins, the iron coins are hit and then fall on a display board and rotate, and a statistic device is installed at the top in the transparent box. According to the invention, after the iron coins are hit by the transmitting device, the iron coins rotate on the display board, and finally the iron coins are changed from a vertical state to a horizontal state, and compared with the phenomenon that the iron coins are overturned and fall, the influence of the immobilization of the transmitting device on the randomness of the iron coin experiment is avoided, thereby making the experiment more convincing.

Description

technical field [0001] The invention relates to the technical field of mathematics teaching devices, in particular to a simulation demonstration teaching aid for mathematics probability statistics. Background technique [0002] In the teaching process of mathematical probability and statistics courses, teachers generally prepare some probability simulation demonstration teaching aids to carry out some simulation experiments, such as coin flipping, dice throwing and normal distribution experiments, to facilitate students' understanding. One of the most commonly used simulation demonstration teaching aids is the coin toss experiment. By tossing the coin multiple times and counting the number of times the coin appears, the probability of the positive and negative sides of the coin being counted is 1 / 2. [0003] At present, some devices change the traditional manual coin toss into automatic coin toss, such as the advanced mathematics probability demonstration device of CN1047156...
