Description

Multifunctional teaching board for pedagogy teaching

technical field

The invention relates to the technical field of teaching tools, in particular to a multifunctional teaching board for pedagogy teaching.

Background technique

In schools, the blackboard is one of the most important parts of the classroom, as a medium for teachers to impart knowledge. The traditional blackboard can only be used by the teacher to write on the blackboard with chalk. The problems of the traditional blackboard have always been the single function, troublesome cleaning of the blackboard handwriting, and the great harm of chalk dust to the teacher's body. With the increasing popularity of electronic intelligent products, the education industry also attaches great importance to technological change. Under the influence of the trend of intelligent teaching tools, multimedia blackboards and smart blackboards are gradually popularized in most educational environments.

The multimedia blackboard is a large touch screen, no need to write with chalk, and can impart knowledge in multiple ways. The contents of the screen cannot be seen clearly on the screen, and the writing experience of the existing touch screen is much worse than that of paper or traditional blackboards, and the writing experience is poor. A smart blackboard usually includes a spliced main screen and sub-screens set on opposite sides of the main screen. The main screen can be operated by touch to present teaching content in the form of pictures, videos, etc., and the sub-screen can be used for users to write on the blackboard with chalk. way of presenting teaching content. The main screen has the problem of ordinary touch screen, while the secondary screen is written with chalk, which has the problems of troublesome cleaning and great hazards of chalk dust.

Contents of the invention

The purpose of the present invention is to provide a multi-functional teaching board for pedagogy teaching, which utilizes the dynamic combination of liquid crystal screen and ink screen, which can not only facilitate teachers to impart knowledge in a variety of ways, but also achieve better writing experience without using chalk. It is more helpful for teachers to impart knowledge.

Above-mentioned technical purpose of the present invention is achieved through the following technical solutions:
