Probability theory experiment model teaching aid

Abstract

The invention belongs to the technical field of a mathematics teaching aid and particularly relates to a probability theory experiment model teaching aid. The teaching aid comprises a casing, a support, a disposing groove, a buffer hole, an ejection groove and an ejection module, wherein the ejection module comprises a first limit unit, a second limit unit, a guide column, a fixing block and a spring, the first limit unit and the second limit unit have the same structures and are symmetric to each other, the first limit unit comprises a pressing column, a swing plate and a rope, one end of thepressing column is hinged with one end of the swing plate, the pressing column moves to push the swing plate to rotate around a rotation shaft, one side of an upper end of the swing plate is providedwith two half-circle projections, one side of a lower end of the swing plate is fixedly connected with the rope, the rope is fixedly connected with a lower end of the guide column after passing through a guide roller, an upper end of the guide column is fixedly connected with a bottom portion of the spring, and the spring is arranged between the two swing plates. The probability theory experimentmodel teaching aid is advantaged in that through setting the ejection module, a batch of coins are ejected, continuous ejection of the coins can be achieved, and experiment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mathematics teaching aids, in particular to a probability theory experimental model teaching aid. Background technique [0002] Probability, also known as probability, chance rate, chance (probability) or possibility, is a basic concept of probability theory. Probability is a measure of the possibility of a random event occurring, and generally a real number between 0 and 1 represents the possibility of an event occurring. The closer to 1, the event is more likely to occur; the closer to 0, the event is less likely to occur, which is an objective argument rather than a subjective verification. [0003] In college advanced mathematics, in order to enable students to learn the knowledge of probability more intuitively, teachers often conduct some practical demonstration experiments of probability. The probability of a coin ending up heads or tails is 1 in 2. [0004] Existing artificial coin tossing expe...

AI Technical Summary

Problems solved by technology

[0004] Existing artificial coin tossing experiments are often carried out by one hand tossing a coin and another person counting next to the experiment. However, due to the large number of experiments required, a lot of manpower and material resources are required, so the current mathematical probability coin tossing experiments often use Computer simulations, computer simulation experiments prevent students from personally participating in probability experiments, so that students cannot deepen their understanding of probability
