Problems solved by technology

[0003] In the teaching of mathematics, probability demonstration devices are often used to strengthen students' understanding of probability. However, the existing probability demonstration devices have a single structure and can only perform probability demonstrations in a single way, which is inconvenient to operate. The effect is not intuitive enough, which is not conducive to improving the learning efficiency of students and the teaching efficiency of teachers

Embodiment 1

[0017] see Figure 1-3 , in an embodiment of the present invention, a portable probability demonstration device for mathematics teaching includes a base plate base 18 on which a first bracket 17 and a second bracket 23 are installed respectively, and the upper end of the first bracket 17 A support shaft 10 is installed for rotation, and a plurality of adjustable telescopic devices 5 are installed and fixed in a circumferential distribution on the support shaft 10. The outer end of the adjustable telescopic device 5 is installed and fixed with a first probability demonstration component 1, and the second bracket 23 The upper end is fixed with a second probability demonstration assembly 24, and the pneumatic device 21 connected to the bottom of the second probability demonstration assembly 24 is also installed on the base plate seat 18; it also includes a manual assembly 13, and the manual assembly 13 passes through a pulley drive assembly The transmission rod 16 is connected wi...

Embodiment 2

[0023] see figure 1 , the difference between this embodiment and embodiment 1 is:

[0024] In this embodiment, the first probability demonstration component 1 includes a first transparent spherical shell 2, the interior of the first transparent spherical shell 2 is evacuated, and a number of first numbered balls 4 are arranged in the first transparent spherical shell 2. The first number ball 4 can be marked with continuous Arabic numerals, which can be distinguished. The first transparent spherical shell 2 is symmetrically provided with two first protrusions 3 centered on the center of the first transparent spherical shell 2, so The first protruding part 3 is a hemispherical structure, and the first protruding part 3 can only accommodate one of the first numbered ball 4, and the central axis of the two first protruding parts 3 is the same as that of the adjustable telescopic device 5. Vertically, the first protruding part 3 is used to house the first numbered balls 4 marked w...

Abstract

The invention relates to the technical field of mathematics teaching, and specifically discloses a portable probabilistic demonstration device which is used for mathematics teaching. The portable probabilistic demonstration device comprises a bottom plate base, a first support and a second support are installed on the bottom plate base; a supporting shaft is rotatably mounted at the upper end of the first support; a plurality of adjustable telescopic devices are fixedly installed on the supporting shaft in the circumferential direction, a first probability demonstration assembly is fixedly installed at the outer ends of the adjustable telescopic devices, a second probability demonstration assembly is fixedly installed at the upper end of the second support, and a pneumatic device connectedwith the bottom of the second probability demonstration assembly is further installed on the bottom plate base; the portable probabilistic demonstration device also comprises a manual assembly whichis respectively connected with the supporting shaft and the pneumatic device through a belt wheel transmission assembly and a transmission rod. Probability demonstration of two modes can be carried out at the same time by using the portable probabilistic demonstration device, operation is convenient, improvement on the learning efficiency of students and the teaching efficiency of teachers is facilitated, and the portable probabilistic demonstration device has good application prospects.

Description

technical field [0001] The invention relates to the technical field of mathematics teaching, in particular to a portable probability demonstration device for mathematics teaching. Background technique [0002] Probability, also known as probability, chance rate and probability rate, is a basic concept of mathematical probability theory, a real number between 0 and 1, and a measure of the possibility of random events. Probability can describe the internal mechanism and regularity in complex systems, and it is used in mathematics, statistics, physics, artificial intelligence, computer science, philosophy and other disciplines. The concept of probability is also often applied in life, such as risk assessment and other Financial market transactions, etc. [0003] In the teaching of mathematics, probability demonstration devices are often used to strengthen students' understanding of probability. However, the existing probability demonstration devices have a single structure and...
