Demonstration device facilitating the teaching of high school mathematics

Abstract

The invention particularly relates to a demonstration device facilitating the teaching of high school mathematics, which belongs to the technical field of teaching devices. The problems of the prior art that the specific demonstration direction is not explicitly indicated to the device, the demonstration device is single in structure and can only demonstrate one type of demonstration and the demonstration process is complex, and the effect is not obvious can be solved. The following scheme is provided and comprises a base. A counter bore is formed in the middle of the top of the base, and a bearing is welded to the inner wall of the counter bore. A connecting rod is welded to the inner wall of the bearing, and the top of the connecting rod is connected with a demonstration frame through abolt. A function demonstration groove is formed at the top of the outer wall of one side of the demonstration frame. According to the invention, the function part of high school mathematics can be demonstrated, and the teaching efficiency of teachers is improved; the abstract concept is changed into concrete object, so that the teaching of the teacher becomes easier; the brightness of the device can be increased, and the teacher can conveniently write the content of the demonstration during explanation; through demonstration and writing, the demonstration effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a demonstration device for high school mathematics teaching. Background technique [0002] At present, geometric figures such as circles, ellipses, and parabolas are the basic two-dimensional figures in mathematics learning, but in the teaching process, teachers have to draw two-dimensional coordinate systems on the blackboard over and over again, and draw such figures. When drawing, it is not like a circle that can be drawn with the help of tools. It can only be drawn through the experience of teachers. In addition, probability problems are often involved in high school mathematics teaching. Because probability is relatively abstract, it is difficult for students to understand it. With the probability teaching aids used, students can only rely on the teacher's explanation to understand probability theory. This teaching method makes students' understanding and mastery ...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following deficiencies: the device does not clearly point out the specific demonstration direction, the demonstration device has a single structure, and can only demonstrate one type, and the demonstration process is complicated, and the effect is not obvious

And above-mentioned patent can not solve this type of problem, therefore, need badly a kind of demonstration device that is convenient to high school mathematics teaching
