Abstract
The utility model discloses a mathematics image demonstrator, relates to mathematics teaching equipment, and concretely relates to an image teaching demonstrator during teaching of higher mathematics. The mathematics image demonstrator comprises a box body (1) and a touch display screen (3), wherein a sucker (2) is fixed on the back of the touch display screen, a computer host (4) is arranged in the box body, an inclined panel (6) is arranged on the upper surface of the box body, a keyboard (7) is fixed on the inclined panel; one sound box (5) is respectively fixed on left, right sides of the box body; the computer host is connected with the touch display screen by a conduction line and also connected with a handwriting pen (8) by a conduction line, the handwriting pen is arranged in a spring clamp on the side surface of the touch display screen; and the computer host is also connected with a microphone (9) by the conduction line. The mathematics image demonstrator solves the problems that during the university mathematics teaching, drawing standard mathematics images on a blackboard takes a long time by teachers, and the drawn image has relatively large error, resulting into forming imprecise function curves and not standard images.
Description
Technical field
The utility model relates to mathematical education equipment, the image teaching demonstration device that uses when being specifically related to Higher Mathematics Teaching.
Background technology
In College Mathematics Teaching, often need to draw some figures, curve etc. on blackboard.Teacher's mathematic graph of drawing standard on blackboard needs the long period, and the larger error of the figure of drawing existence, causes the shape of function curve out of true, figure nonstandard, can affect student's visual experience, affects quality of instruction.
The utility model content
The utility model provides the mathematical image graphic demonstrator, the utility model has solved in College Mathematics Teaching, teacher's mathematic graph of drawing standard on blackboard needs the long period, and there is larger error in the figure of drawing, causes the problems such as the shape of function curve out of true, figure is nonstandard.
For addressing the above problem, the utility model adopts following technical scheme: the mathematical image graphic demonstrator, comprise casing 1 and touch display screen 3, touch display screen 3 back sides are fixed with sucker 2, be provided with main frame 4 in casing 1, oblique panel 6 is arranged above casing 1, be fixed with keyboard 7 on oblique panel 6; Respectively be fixed with an audio amplifier 5 at casing 1 left and right sides; Main frame 4 connects touch display screen 3 by wire; Main frame 4 also connects writing pencil 8 by wire respectively, and writing pencil 8 is arranged in the spring clamp of touch display screen 3 sides; Main frame 4 also connects a microphone 9 by wire.
The utility model advantage: one, can intuitively show accurately mathematic graph, the teacher can also operate by writing pencil; Two, simple in structure, easy to use; Three, use the utility model can make the teacher intuitively demonstrate accurately mathematic graph, improve the effect of mathematical education.
