Description
Technical field
This utility model is related to a kind of College Maths probabilistic model teaching aid.
Background technology
Probability because being to compare abstract concept, in College Maths theory of probability course, if can demonstrate by probability teaching aid
Cooperation explanation, can make student be easier to understand and grasp.And current, because not being suitable for the probability teaching aid of teaching, student can only
Remove to understand probability theory by teacher's explanation, this mode given lessons makes student not high to the understanding of probability and Grasping level, religion
Teacher is also very painstaking during explanation.Therefore, it is badly in need of a kind of teaching probability teaching aid and carry out cooperation teaching.
Utility model content
The technical problems to be solved in the utility model be provide a kind of structure be simple and convenient to operate, safe university
Mathematical probabilities model teaching aid.
For solving the above problems, this utility model adopts the following technical scheme that
A kind of College Maths probabilistic model teaching aid, including model base, column, rubber cushion, figure demonstrating plate, clipboard, bar
Shape post, lampion, control button panel and framework, are provided with column above described model base, set above described model base
It is equipped with framework, in described framework, is provided with demonstration device for probability, clipboard and figure demonstrating plate, described demonstration device for probability includes
Bar shaped post and lampion, described bar shaped post is internally provided with fix bar, and described fix bar lower end is fixedly installed in model base,
Described bar shaped post is cooperated with model base by fix bar and is connected, and described model base is provided with and a pair of bar shaped post 1
The lampion answered, described bar shaped post is provided with jack, on described jack, spiral is provided with pole, described bar shaped post passes through prop up
Bar is provided with demonstration line, and the cross bar of described framework is provided with slot, and described bar shaped post passes through jack and slot through pole and frame
Frame cooperates connection, and described framework is provided with control button panel.
Preferably, being provided with graduation mark on described column.
Preferably, being provided with several rubber cushions below described model base.
Preferably, described bar shaped post moves up and down regulation by pole and jack in fix bar.
This utility model reasonable in design, easy for operation, demonstration device for probability is arranged on model base, writes
Plate and figure demonstrating plate, carry out probability demonstration respectively, write and figure demonstrating operation；More intuitively show probability system to student
Meter, figure demonstrating and teaching point, greatly improve efficiency of giving lessons, have very big using value.
