Abstract
The invention relates to a teaching aid for Chinese teaching in a university. The teaching aid comprises a blackboard body. The blackboard body comprises a blackboard frame, a first blackboard, a second blackboard and a curtain. The first blackboard and the curtain are inlaid in the blackboard frame side by side. Sliding grooves are respectively formed in the upper part and the lower part of the blackboard frame outside the first blackboard and the curtain. The second blackboard is mounted on the blackboard frame by means of the sliding grooves and can slide. The length of the second blackboard is equal to or smaller than that of the first blackboard. The teaching aid solves the problems that a traditional blackboard cannot be used as the curtain of a slide, and dust flies in the wiping process; writing of teachers is greatly reduced during the process of Chinese teaching in the university, and besides, lectures of the teachers are richer and more vivid so as to facilitate understanding of students; and moreover, the influence on human health, which is caused by the fact that dust flies during the wiping process, is avoided.
