All-touch intelligent historical map teaching extensible demonstration device

Abstract

The invention discloses an all-touch intelligent historical map teaching extensible demonstration device which comprises a bottom plate; four universal wheels with brake blocks are uniformly installedon the lower surface of the bottom plate; the middle part of the upper surface of the bottom plate is fixedly connected with the lower end of a telescopic rod; and the upper end of the telescopic rodis fixedly connected with the middle part of the lower surface of an all-touch display. By adopting the all-touch intelligent historical map teaching extensible demonstration device provided by the invention, a transparent plate is convenient to mount, a teacher uses a roller ball pen to write new extended contents, corresponding to original knowledge points, on the front side surface when needing to extend some knowledge points which do not exist on PPT, and understanding of students is facilitated; a supporting frame prevents the all-touch display from toppling as the teacher writes on thetransparent plate, so that the stability of the all-touch intelligent historical map teaching extensible demonstration device is improved; and the teacher moves scrubbing sponge up and down through aU-shaped fixed frame, the scrubbing sponge erases the written contents on the transparent plate, and the U-shaped fixed frame and the scrubbing sponge lighten the work intensity of the teacher.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an expandable demonstration device for full-touch intelligent historical map teaching.

Problems solved by technology

However, because students are generally under the pressure of entrance examinations, they think that history is a sub-subject, and they don’t pay enough attention to it ideologically. As a result, the teaching effect of history teachers is poor, and it is difficult to improve the grades of history subjects. Students are tired of learning and abandonment.

When the teacher is in class, sometimes he needs to extend some knowledge points that are not on the PPT, so he can only dictate or describe on the blackboard, which is not easy for students to understand
