Description

TECHNICAL FIELD

[0001] The present application relates to a history timeline demonstration aid. BACKGROUND

[0002] In the process of history teaching, the history teacher will generally explain in detail the content that the students must remember according to the progress of the teaching, but it is difficult to remember the content such as the name of the dynasty and the time period of its existence, and a large number of events and their time in history. The traditional teaching method is to require the teacher to prepare a large number of blackboard writing, which will occupy a lot of classroom time, thereby affecting the course progress and the amount of extracurricular knowledge, which is not conducive to improving the teaching quality. Now the history timeline is used to display the historical events. The history timeline is a tool for sorting and displaying the development of historical events. Usually, the important events, changes and turning points of each period are marked on the axis with time sequence as the main line, which helps people understand the evolution of history more clearly.

[0003] When the history timeline is demonstrated, the history timeline is usually fixed on the demonstration aid for demonstration. However, the common fixing frame is large in size, and it is not convenient to store the demonstration aid after the history timeline demonstration is finished. Moreover, after a history course is finished, the history timeline is directly rolled up, and the next time it is used, the timeline needs to be unfolded again and the last learning position needs to be found, which needs to waste a certain amount of time and reduces the teaching efficiency.
