Abstract
The utility model relates to a demonstration instrument, particularly, a function curve comparison demonstration instrument. The objective is to solve the problem of influence on learning of students who have a weak learning foundation caused by the lack of interest which is further caused by the singleness of the teaching mode of teachers and limitation of mathematics teaching aids. According to the function curve comparison demonstration instrument of the utility model, the upper end surface of a base (1) is provided with a groove (2); a first comparison demonstration panel (3) and a second comparison demonstration panel (4) are slidably arranged on the groove (2) of the base (1) side by side; the right side wall of the first comparison demonstration panel (3) is provided with a first insertion opening (9); the left side wall of the second comparison demonstration panel (4) is provided with a second insertion opening (10); a first curve plate (7) and a second curve plate (8) are respectively inserted in a first lining plate (5) and a second lining plate second (6); and the first lining plate (5) and the second lining plate (6) are respectively arranged in the first insertion opening (9) and the second insertion opening (10). The function curve comparison demonstration instrument of the utility model is applied to mathematics teaching.
Description
Technical field
The utility model relates to a kind of demonstrator, is specifically related to a kind of function curve contrast demonstrator, belongs to mathematics teaching aid field.
Background technology
Higher mathematics is one of subject important in colleges and universities, it is the basis of learning each subject well, student for some Fundamentals of Mathematics weaknesses, the speed of teachers' instruction and teacher lecture the effect of listening to the teacher that mode directly has influence on these students, yet, due to the finiteness of mathematics teaching aid, cause teachers' instruction mode single, make the student of most weak foundations lack learning interest, affect its school grade.
Utility model content
The purpose of this utility model is the problem that there is no at present function curve demonstrator in order to solve, and then a kind of function curve contrast demonstrator is provided.
The technical solution of the utility model is: a kind of function curve contrast demonstrator comprises base, the upper surface of base is provided with groove, described curve comparison demonstrator also comprises the first contrast demonstration panel, the second contrast demonstration panel, the first interior lining panel, the second interior lining panel, the first drawing curve and the second drawing curve, the first contrast demonstration panel and the second contrast demonstration panel are slidably arranged on the groove of base side by side, the right side wall of described the first contrast demonstration panel is provided with the first insert port, the left side wall of the second contrast demonstration panel is provided with the second insert port, the first drawing curve and the second drawing curve are inserted into respectively in the first interior lining panel and the second interior lining panel, the first interior lining panel and the second interior lining panel are separately positioned in the first insert port and the second insert port.
Described the first contrast demonstration panel and the second contrast demonstration panel are transparent demonstration panel.
On described the first contrast demonstration panel and the second contrast demonstration panel, be equipped with rectangular coordinate system.
Described curve comparison demonstrator also comprises a plurality of pulleys, and a plurality of pulleys are separately positioned on the lower surface of the first contrast demonstration panel and the second contrast demonstration panel.
The utility model compared with prior art has following effect:
1. the utility model in use, not only two function curves can be contrasted to explanation respectively on the first contrast demonstration panel and the second contrast demonstration panel, can also two or more pieces function curve be demonstrated and be explained in the same coordinate system simultaneously, contrast obviously, be convenient to student and understand, in the process of giving lessons, just can leave deep impression to student, be conducive to improve student's memory depth, improve learning interest, and then improve student's school grade.
2. the first contrast demonstration panel of the present utility model and the second contrast demonstration panel can slide on the groove of base, give lessons lively flexibly, and the first drawing curve in the first interior lining panel and the second interior lining panel and the second drawing curve are changed easily, are convenient to operation of teacher.
3. the utility model is simple in structure, is convenient to manufacture, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises base 1, the upper surface of base 1 is provided with groove 2, described curve comparison demonstrator also comprises the first contrast demonstration panel 3, the second contrast demonstration panel 4, the first interior lining panel 5, the second interior lining panel 6, the first drawing curve 7 and the second drawing curve 8, the first contrast demonstration panel 3 and the second contrast demonstration panel 4 are slidably arranged on the groove 2 of base 1 side by side, the right side wall of described the first contrast demonstration panel 3 is provided with the first insert port 9, the left side wall of the second contrast demonstration panel 4 is provided with the second insert port 10, the first drawing curve 7 and the second drawing curve 8 are inserted into respectively in the first interior lining panel 5 and the second interior lining panel 6, the first interior lining panel 5 and the second interior lining panel 6 are separately positioned in the first insert port 9 and the second insert port 10.
As a kind of optimal way, the first contrast demonstration panel 3 of the present utility model and the second contrast demonstration panel 4 are transparent demonstration panel.So design, is convenient to the curve on the first drawing curve 7 and the second drawing curve 8 completely to have an X-rayed out good demonstration effect.
As a kind of optimal way, on the first contrast demonstration panel 3 of the present utility model and the second contrast demonstration panel 4, be equipped with rectangular coordinate system.So design, being convenient to, when different curves is contrasted, has contrast benchmark.
As a kind of optimal way, curve comparison demonstrator of the present utility model also comprises a plurality of pulleys 11, and a plurality of pulleys 11 are separately positioned on the lower surface of the first contrast demonstration panel 3 and the second contrast demonstration panel 4.So design, is convenient to the slip of the first contrast demonstration panel 3 and the second contrast demonstration panel 4.
