Abstract
The utility model relates to the field of teaching aids, in particular to a probability model teaching aid used for mathematical education in a university. The probability model teaching aid comprises a board and more than one bar groove. The bar grooves are evenly arranged on the board longitudinally. Through holes are reserved on the board and at the top of the bar grooves. One sliding bar penetrating through each through hole is arranged in each bar groove. By the means of adjusting the sliding bars and particularly arranging indicating colors in the sliding bar grooves, demonstration of probability can be represented intuitively; different colors are selected for adjacent bar grooves, demonstration therefore is more remarkable and visual, and understanding and learning in a probability course is beneficial for students; and the probability model teaching aid has the advantages of high attraction and easy operation when being used for demonstration.
Description
Technical field
The utility model relates to teaching appurtenance field, relates in particular to a kind of College Mathematics Teaching probability model teaching aid.
Background technology
Probability in big immunologing mathematics theory of probability course, if can cooperate explanation by the demonstration of probability teaching aid, can make the student be more readily understood and grasp because being the comparison abstract concept.And at present, because being fit to the probability teaching aid of teaching usefulness, the student can only explain by the teacher and understand probability theory, and this mode of giving lessons makes the student not high to understanding and the grasp degree of probability, the teacher in the process of explanation also very painstakingly.Therefore, be badly in need of a kind of teaching and cooperate teaching with the probability teaching aid.
Summary of the invention
Of the present utility modelly be intended at the deficiency that exists in the background technology, and a kind of College Mathematics Teaching probability model teaching aid is provided.
A kind of College Mathematics Teaching of the utility model probability model teaching aid, be to be constituted by plate body and bar-shaped trough, vertically be laid with more than one bar-shaped trough on its plate body, there is open-work on the top of bar-shaped trough at plate body, and the slider bar that passes open-work is arranged in each bar-shaped trough.
As further improvement of the utility model, be equipped with the indication color in each bar-shaped trough.
As further improvement of the utility model, described plate body top is provided with more than one link, and avris is provided with scale.
A kind of College Mathematics Teaching of the utility model probability model teaching aid, by regulating slider bar, be provided with the indication color when especially in bar-shaped trough, sliding and express the demonstration of probability intuitively, and can select different colors for use in the adjacent bar groove, demonstrate more directly perceived, more eye-catching, be beneficial to student's understanding and this subject of study probability, when demonstration, have eye-catching, easy-operating characteristics.
Description of drawings
Fig. 1 is one-piece construction synoptic diagram of the present utility model.
Embodiment
Below in conjunction with 1 pair of a kind of College Mathematics Teaching of the utility model of accompanying drawing probability model teaching aid, be described further;
A kind of College Mathematics Teaching of the utility model probability model teaching aid, be to be constituted by plate body 1 and bar-shaped trough 2, vertically be laid with more than one bar-shaped trough 2 on its plate body 1, there is open-work on the top of bar-shaped trough 2 at plate body 1, and the slider bar 3 that passes open-work is arranged in each bar-shaped trough 2.Be equipped with indication color 4 at each bar-shaped trough 2 bottom land, plate body 1 top is provided with more than one link 5, and avris is provided with scale 6.
