Description
Technical field
The invention belongs to teaching aid technical field, relate to a kind of multi-functional group of probability learning
Box-like teaching aid.
Background technology
Teacher is saying probability class hour now, does not has teaching aid to use, and is merely able on blackboard use
Word and language are explained, and probability originally compares abstract concept, with this kind of side
Method explanation is difficult to make student quickly understand.
Such as, Chinese patent application [application number: 201320257234.5；Publication number
203217830U], disclose a kind of College Mathematics Teaching probability mold teaching aid, its bag
Containing magnet-type chassis, dividing plate, Teaching Module, sucker, the multiple separation in magnet-type chassis
Plate is divided into the space that several shapes and sizes are consistent, is provided with Teaching Module in space,
It is provided with sucker, it is characterised in that it also comprises at the corner at the back side on magnet-type chassis
Magnet, observation window, roller one, rotating shaft, swivel base, adjusting knob, roller two,
Two magnet are separately positioned on the two ends within Teaching Module, the leading flank of Teaching Module with
Trailing flank is provided with observation window, and two swivel bases are separately positioned on inside Teaching Module
Bottom, swivel base is provided with rotating shaft, roller one, roller two are separately mounted to two
In individual rotating shaft, roller one, the upper end of roller two are provided with adjusting knob.
And for example, Chinese patent application [application number: 201320147177.5；Publication number
203118292U], disclose a kind of College Mathematics Teaching probabilistic model teaching aid, be by
Plate body and bar-shaped trough are constituted, it is characterised in that be longitudinally laid with more than one on plate body
Bar-shaped trough, the top of bar-shaped trough has open-work on plate body, have in each bar-shaped trough through
The slider bar of open-work.
But above-mentioned existing two teaching aid functions are the most single, when lecturer had both needed utilization to turn over
Dynamic Teaching Module show the single probability bar indicating probability that needs again to stretch and slide when being distributed, just
Need to take two teaching aids simultaneously, inconvenient, and show the teaching aid of single probability by
In using rotating shaft to rotate Teaching Module, therefore Teaching Module location is inaccurate, time in classroom
Preciousness, teacher loses time not necessarily in above this；Additionally it is currently used for learning probability
Teaching aid is usually an entirety, carries and receives the most inconvenient and be not easy to basis
Actual conditions select size.
