Description

Display devices for English language teaching

technical field

The invention relates to the technical field of teaching equipment, in particular to a display device used in English language teaching.

Background technique

In the process of English teaching, because English words or sentences are not easy to understand and it is extremely difficult to memorize, it is necessary to display the words or sentences for students to watch, which can leave time for students to think and memorize, which is beneficial for students to master Knowledge.

The display device is a very commonly used teaching tool. Teachers achieve the purpose of educating students by writing the teaching content on the blackboard of the display device with chalk. Writing with chalk will cause a lot of chalk dust. When you use a blackboard eraser to wipe the blackboard, a lot of chalk dust will fly and pollute the environment and fall on teachers and students, dirtying clothes and exposed hair and skin.

At present, there is no display device that can reduce the flying problem of chalk dust. At the same time, when teachers write on the blackboard, they need to hold a book and write with one hand, which is very inconvenient.
