摘要

A method, device and apparatus for displaying board-writing for teaching, and a computer-readable storage medium. The method comprises: acquiring and saving board-writing images corresponding to the contents of each instance of board-writing on a writing board (110); determining that a user is starting to add a new board-writing instance to the writing board (120); and displaying the last-saved board-writing image on a display terminal disposed adjacent to the writing board (130). The above method addresses the problem in the prior art in which a teacher needs to stop teaching temporarily due to a lack of writing area because board-writing has not yet been removed, and the above method enables extending the writing area such that a teacher can teach according to a scheduled plan, improving the quality of education.
