Abstract

The invention discloses a mathematical probability demonstration device, and belongs to the technical field of teaching tools, the mathematical probability demonstration device comprises a protection cover and a light sensation detector, and further comprises a supporting plate, an ejection assembly, a pushing assembly, a limiting plate, a limiting slide way, an angle adjusting assembly, a conveying belt and a coin recycling assembly, and the supporting plate is provided with a feeding slide way, a material returning slide way and a discharging port; the feeding slide way and the returning slide way are vertically arranged and are communicated with each other, the bottom of the supporting plate is provided with an arc-shaped tumbling slide way connected with the discharge port, the ejection assembly is used for ejecting coins in the feeding slide way, the pushing assembly is used for pushing the coins in the feeding slide way to an ejection position of the ejection assembly, and the number of the limiting plates is two; according to the invention, the three coins are arranged, emitted and collected respectively, so that the data collection efficiency is greatly improved, a large amount of demonstration time is saved, and the problem that a teacher cannot carry the device easily due to overweight of the device is avoided.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a mathematical probability demonstration device. Background technique [0002] When explaining the process of mathematical probability courses, in order to facilitate students' understanding, teachers generally prepare some demonstration teaching aids. One of the most commonly used demonstration teaching aids is the coin tossing experiment, that is, tossing a coin at random multiple times and counting the number of times the coin appears on both sides. Because the more times the coin is tossed, the more convincing it is for the probability event, which makes the traditional demonstration teaching aids have the following disadvantages: the degree of automation is low. Arrangement and statistics cannot be completely separated from manual labor when used. When the number of coin tosses is large, the teaching efficiency will be affected; using more coins is inconvenient to co...
