Description

Education show is with writing device

Technical Field

The invention belongs to the technical field of teaching equipment, and particularly relates to a writing device for education display.

Background

Educators develop the mental development of educated persons in a purposeful and organized way according to laws, regulations and industrial specifications and according to school conditions and job titles, and educate the educators with the prior experiences and learners to explain various phenomena, problems or behaviors for the educators so as to improve the practical ability, and the educators basically cognize things to be treated by a relatively mature or rational thinking of people. In which a person slowly feels a state of cognitive understanding to an object from a sense and forms a relatively perfect or rational self-conscious thinking. However, since a person has both his own consciousness and his own sensory dimension, any educational consciousness may not be absolutely correct, and he should understand his direction of thinking perceptually as long as he does not deviate from the inherent nature of things. Education is also a kind of thought teaching, and people have another thought trend because of their own consciousness form, so, education is taught to people with the most objective and fair consciousness, so the people's thinking will not be too biased, and the people's thinking will gradually mature and be rational because of the abundance of thinking, and thus the most rational self and the most correct thinking cognition will be reached, which is the fundamental place of education.

In teaching, the most common educational device is a blackboard. Over two hundred years, the blackboard is developed from the earliest of being coated on the surfaces of hard objects such as wood boards, cement and the like by black paint to the surfaces of water mill glass, color coated steel plates and composite plates in the nineties. The types of the existing blackboards also become complicated and diversified, and the blackboards, the green boards and the white boards are divided into a plane board and an arc panel from the aspect of surface shapes, and a support movable board, a push-pull board, a lifting board and a magnetic blackboard are divided from the aspect of structural composition.

However, most of the existing blackboards are fixed or lifting type blackboards, and the height and the position of the blackboards can be adjusted at will in the using process. However, the existing blackboard still has a plurality of problems in the using process and is inconvenient to use. In the teaching process, the written content is sometimes required to be displayed in a turning mode, but the existing blackboard cannot be realized, so that the written content can only be redrawn, and time is wasted.
