Abstract
The utility model relates to a probability model teaching appliance used for university mathematics teaching. The probability model teaching appliance comprises a rectangular bottom plate. Four sides of the rectangular bottom plate are provided with baffle plates. Multiple concave pits are evenly distributed on the upper surface of the rectangular bottom plate. The concave pits are internally inlaid with magnetic pats which present to be hemispherical shell structures. The magnetic pats are provided with steel balls. The top part of each steel ball is provided with a number paster which is used for marking. Besides, the surface of the number paster is provided with a fluorescence coating layer. The probability model teaching appliance is simple in structure and reasonable in design, a principle of magnetic mutual attraction is ingeniously utilized, and demonstration of a probability model can be performed by poking position of the small balls so that probability issues are easy for students to understand, and teaching atmosphere and teaching quality in a classroom are enhanced.
Description
Technical field
The utility model relates to the technical field of teaching aid, especially a kind of College Mathematics Teaching probability model teaching aid.
Background technology
In known technical field, probability is because being comparison abstract concept, in College Maths theory of probability course, if can, by the explanation of probability model teaching aid, can make student be easier to understand and grasp.And up to now, because not being applicable to the probability model teaching aid that teacher uses, make teacher can only be on blackboard with language and coordinate figure and word is explained, not only student is not easy to understand, teacher explains also very hard, if can design a kind of teaching aid for probability model, can significantly promote teaching efficiency, be easy to student and understand.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of College Mathematics Teaching simple in structure, efficiently convenient, easy to use probability model teaching aid is provided.
The utility model solves the technical scheme that its technical matters adopts: a kind of College Mathematics Teaching probability model teaching aid, there is rectangular base plate, four sides in described rectangular base plate are equipped with baffle plate, upper surface in described rectangular base plate is evenly provided with a plurality of pits, in described pit, be all inlaid with the magnetic pad that is hemispherical shell body structure, on described magnetic pad, be all placed with steel ball, at the top of described steel ball, be provided with the digital paster that indicates use, and be provided with fluoresent coating on the surface of described digital paster.
Further, consider that when demonstration easy to operately can play position-limiting action again, the bottom of baffle plate described in the utility model is concordant with the bottom of rectangular base plate, and the top of described baffle plate is lower than the peak of steel ball.
Further, more firm in order to place, the utility model is provided with anti-skid rubber cushion in the bottom of described rectangular base plate.
Further, consider dust prevention, the utility model is provided with dustproof cover body above described rectangular base plate.
The beneficial effects of the utility model are: the utility model is simple in structure, principle reasonable in design, to use cleverly magnetic to attract each other, can carry out the demonstration of probability model by stirring the position of bead, be easy to student and understand probability problem, improve teaching atmosphere and the quality of instruction in classroom.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cut-open view of Fig. 1;
In figure: 1. rectangular base plate, 2. baffle plate, 3. magnetic pad, 4. steel ball, 5. anti-skid rubber cushion, 6. dustproof cover body.
Embodiment
