The utility model discloses simple structure can specialize the abstract concept of probability statistics, gives the audio -visual demonstration of student, alleviates the difficult degree of probability statistics teaching, retrieves the spheroid automatically moreover, convenient operation, and the statistics is clear directly perceived.
Description
Technical field
The utility model belongs to instructional device field, and in particular to a kind of Mathematical probability statistics educational devices.
Background technology
In mathematical education, probability statistics are always the part that teacher is most difficult to impart knowledge to students.The concept of probability statistics is very abstract, needs
Student gives free rein to one's imagination understanding, so the very big difficulty of teaching presence, student is difficult the concept for grasping probability statistics.
Utility model content
To solve the problems, such as above technology, the utility model provides a kind of Mathematical probability statistics educational devices,
The abstract concept of probability statistics can be embodied, intuitively be demonstrated to student, mitigate the degree of difficulty of Teaching Probability Theory and Mathematical Statistics.
Its technical scheme is：
A kind of Mathematical probability statistics educational devices, including casing, turntable, gear steering device, joystick, fabric case
Lid and ball taking port, the box house lower end is provided with turntable, and turntable lower end is connected to gear steering device, gear steering device
Joystick is connected to, the hand portion of joystick is arranged on outside casing, fabric case lid is provided with the case mouth of casing, on fabric case lid
It is provided with ball taking port.
Further, displaying pipe is provided with outside the casing, is shown and be provided with pipe switch valve, show pipe upper end open diameter
More than the diameter for showing pipe, show that pipe lower end is connected to casing.
Further, digital block statistics frame and color block statistics frame are provided with outside the casing, casing is outside upper to be provided with numeral
Block place position and color block place position.
Further, digital ball place position and color ball place position are provided with outside the casing.
Further, the box inside is provided with rubber layer.
Further, it is provided with fricting strip on the turntable.
The ball in digital ball place position or color ball place position is selected to be placed in casing according to field research situation, numeral
Ball and color ball are the spheroid of congruence, and simply the numeral or color of top is different, and the sense of touch of staff can not be differentiated.Shake is hand
Bar, by gear steering device turntable is rotated, and the spheroid in agitation box body makes random spheroid be distributed in casing.Box inside
Rubber layer and fabric case lid can reduce shock of the spheroid to casing.Student takes out spheroid by ball taking port, is put into displaying
In pipe, student is seen clearly after numeral or color on spheroid, selects to be counted accordingly in digital block place position or color block place position
Block or color block are put into digital block statistics frame or color block statistics frame is counted.After statistics is completed, open and show in pipe
Switch valve, allow spheroid to flow back in casing.Repeat above step, repeatedly select spheroid, all record is counting frame to final result
It is interior, count inframe statistics can also see clearly take ball order.
The beneficial effects of the utility model：
The utility model simple structure, can embody the abstract concept of probability statistics, intuitively demonstrate to student, mitigate
The degree of difficulty of Teaching Probability Theory and Mathematical Statistics, and spheroid is reclaimed automatically, easy to operate, statistics is clear and intuitive.
