1, junior high school history, senior high school history and university history undertake different tasks according to students' learning stages.

2, junior high school history is mainly to pile up historical facts and understand the historical context.

With the addition of ideological part in the history of senior high school, we began to get used to historical analysis, that is, each part should have corresponding historical significance.

3. University history is a complete ideology, that is, thinking about the true colors of history through ideological thinking (historical materialism). Theoretically, if you can analyze historical problems through ideology, you can use ideology to analyze practical problems to solve problems in your current work.

Therefore, junior high school students have learned modern history, and universities still have to learn it.
