Cultivating students' concept of time is one of the tasks of history teaching. Studying history, without the concept of time, it is impossible to analyze the causal relationship between historical events and grasp the regularity of historical development. Therefore, students should be required to remember the important years that mark the historical development.

2. Cultivate students' concept of space

Cultivating students' concept of space is also an important task in history teaching. Learning history, without the concept of space, can't understand the exact location of historical events, and can't have a correct understanding of historical events and historical figures. So remember the occurrence and place of major historical events.
