English teaching aid

Abstract

The invention discloses an English teaching aid, which comprises a board body, and is characterized in that a working part, a handwriting clearing mechanism, a scoring mechanism, a control mechanism and a shaking buffer mechanism are sequentially arranged on the board body; wherein the working part comprises supporting legs, a display screen and a writing blackboard; the supporting legs are arranged at the lower end of the plate body, and main supporting rods of the supporting legs adopt telescopic mechanisms; the display screen and the writing blackboard are sequentially arranged on the frontsurface of the board body. The erasing mechanism can be used for erasing handwriting on the writing blackboard, the handwriting removing mechanism can drive the erasing mechanism to move in the horizontal direction and the vertical direction, erasing is more comprehensive, the erasing effect is improved, and the problems are solved that when teachers and students suffering from respiratory tractand lung diseases erase the handwriting on the blackboard, dust can be easily sucked into respiratory tracts and lungs to cause aggravation of illness, and manual chalk handwriting erasing is low in efficiency and high in labor intensity.

Description

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: the prior art realizes accurate and fast marking by setting a four-line three-grid device, which improves the quality of English teaching, but writing After completion, the erasure of chalk handwriting still needs to be done manually. For teachers and students suffering from respiratory and lung diseases, when erasing blackboard handwriting, it is easy to inhale dust into the respiratory tract and lungs, which will aggravate the condition and affect their health. Manual erasing of chalk handwriting has the problems of low efficiency and high labor intensity; at the same time, after the students have finished writing, teachers need to distinguish and score each one, which is inefficient, and different teachers will have different scoring results due to different personal judgments , which is not conducive to uniform standards. In addition, teachers will be prone to fatigue after working for a long time, which is not conducive to improving the quality of English teaching
