Applied mathematics probability event teaching method and apparatus

Abstract

The invention discloses an applied mathematics probability event teaching apparatus which includes a pedestal. The internal wall of the pedestal is fixedly provided with a ball dispenser thereabove. The ball dispenser is connected to a storage mechanism thereabove through a support rack. The storage mechanism includes a ball storage funnel, a hollow rotating shaft, an electric machine, a transmission mechanism and a ball delivering rotating disk which are fixed on the support rack. The upper end of the ball storage funnel is provided with a cover plate. One side of the cover plate is provided with a ball inlet. The electric machine is disposed on the cover plate. The electric machine is connected to the hollow rotating shaft through the transmission shaft. The upper end of the hollow rotating shaft is installed in the middle part of the cover plate through a bearing. The lower port of the hollow rotating shaft penetrates the lower part of the ball storage funnel and is provided with a ball dropping rotating disk. The ball dropping rotating disk is provided with a electromagnetic valve thereon. The electromagnetic valve is in electrical connection to a controller which is disposed on the support rack. The apparatus here can increase students' interest in class, by arranging demonstration balls and coins, can better determine randomness of probability and better exhibit features of probability, and increases learning quality. The apparatus herein has the characteristics of reasonable design, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of mathematics teaching equipment, in particular to a teaching method and device for applied mathematics probability events. Background technique [0002] In the teaching of probability, since beginners cannot understand the principle of probability and the generation of probability, it is necessary to use the probability teaching demonstration device when explaining probability, and demonstrate the occurrence of something intuitively. It enables observers to intuitively understand the generation process of probability, which is more conducive to the cognition of probability. [0003] However, most of the probability teaching demonstration devices at the present stage are composed of simple structures, which are manually operated by the user, and then counted manually, and the final results are reflected to the students. Although this device is simple in structure and low in cost, However, it is very inconv...

Problems solved by technology

[0003] However, most of the probability teaching demonstration devices at the present stage are composed of simple structures, which are manually operated by the user, and then counted manually, and the final results are reflected to the students. Although this device is simple in structure and low in cost, But it is very inconvenient to use, it cannot give people the most intuitive observation experience, and it is easy to affect the occurrence of probability events by various factors, so it cannot well meet the various necessary requirements for the demonstration of probability teaching at this stage
