Description

A Chinese multimedia teaching projection device

technical field

The utility model relates to the technical field of teaching tools, in particular to a Chinese multimedia teaching projection device.

Background technique

Chinese multimedia teaching is to organically combine various elements of multimedia (such as text, drawing, sound, video, etc.) according to teaching requirements, and display them to students through screens and projector projections to complete the teaching or training process. In the process of Chinese multimedia teaching, the main content displayed by the projection includes text information such as poems, poems, and prose, as well as information such as pictures and videos that match the context. Compared with traditional blackboard teaching, Chinese multimedia teaching has the ability to make teaching more It is a vivid feature, and at the same time, the amount of teaching information is larger, which is more convenient for students to learn Chinese. In the process of Chinese multimedia teaching, the essential equipment is a projection device, but because some occasions (such as ordinary classrooms) do not have projectors, or some occasions (such as in the square) cannot install projectors, which makes it impossible to install projectors in these places. It is very difficult to conduct Chinese multimedia teaching on special occasions, and the pages are turned too fast in the process of multimedia teaching, which makes students unable to learn quickly and reduces the efficiency of teaching. Because of such problems, it is necessary to invent a structure A projection device for Chinese multimedia teaching that is simple, convenient for teaching and students' memory, and convenient to move.
