Problems solved by technology

This invention has developed a simple teaching model. By dividing the disk, it is convenient to understand the function image. However, the drawing of the image still needs to be drawn by hand, and the movement of the image cannot be realized quickly, and it is only applicable to the sine function. Applicability Not strong

Abstract

The invention discloses an image generation demonstration device for teaching, and the device comprises a housing and a plurality of electronic display screens which is cooperatively nested in the housing. The housing comprises a pedestal and a fixed cover disposed at the upper end of the pedestal. The other end of the fixed cover is of a hollow structure with one opened end, and the interior of the fixed cover is provided with an accommodation cavity, wherein one side end face is provided with a transparent glass layer. The upper and lower end faces of the accommodation cavity are respectively provided with a plurality of insertion strips which are installed along the long axis of the fixed cover. The electronic display screen comprises a transparent display screen which is cooperatively nested in the accommodation cavity, and a control panel which is connected with a side edge of the transparent display screen. The control panel is provided with a plurality of image output control keys and a color control key. The device is mainly used in the teaching process of trigonometric functions, displays the corresponding function images on the transparent display screen through the input of the control panel, and then enables the transparent display screen to be inserted into the accommodation cavity. Moreover, a plurality of transparent display screens can be inserted for the comparison of images and the movement of the images and for bringing convenience to students for full understanding.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to an image generation and demonstration device for teaching. Background technique [0002] In the teaching process, students’ comprehension ability is often triggered by auxiliary tools. The knowledge of trigonometric functions is a major difficulty in the teaching process, including image analysis, image movement, etc. Hand-painted images are easy to affect students’ comprehension due to errors. At the same time, hand-painting also increases the difficulty of the teacher's work, and the efficiency does not necessarily improve. [0003] In the utility model with the patent number 201420377450.8, a demonstration device for generating a sine function image is mentioned, which includes a disk, which is characterized in that the circular surface and the circumference of the disk are divided into twelve equal parts, and the equal division area is divided into two different types....
