Abstract

The invention discloses a university maths event teaching demonstration device based on big data analysis. The device comprises a box, a feeding box is mounted at the upper end of the box, multiple air outlets are formed in the top wall of the feeding box, multiple plastic balls are placed in the feeding box, two protection plates are symmetrically arranged in the box obliquely, a limiting sleeveis jointly connected on the protection plates, multiple retaining blocks are uniformly mounted on the inner side wall of the box, multiple ball outgoing pipes are uniformly mounted on the inner side wall of the box, an infrared sensor is mounted on the inner side wall of each ball outgoing pipe, and a guide net is obliquely arranged below the ball outgoing pipes. The device has the advantages thatthe device is ingenious in structure and convenient in use, mechanization of small ball counting is realized, and operation energy of labor is saved; the number of experiment samples is increased, sothat experiment results are closer to an ideal value, experiment accuracy is ensured, and reference value of experiment data is increased.

Description

technical field [0001] The invention relates to the technical field of educational teaching aids, in particular to a university mathematics probability event teaching demonstration device based on big data analysis. Background technique [0002] When teachers demonstrate mathematical probability occurrences, they often use a coin toss, record the number of occurrences of heads and tails, and then make simple statistics. Higher, this kind of simple mathematical probability demonstration device has no substantial help to the learning of university mathematical probability theory. Teachers simply rely on theoretical explanations to explain, and it is difficult for students to master relevant knowledge. A probability generation demonstration device is needed for auxiliary teaching. [0003] In the existing market, there is a kind of teaching aid with the blocking column as the selection condition, but the operator needs to do it manually when counting the balls. The operation pr...
