In fact, history lessons in the United States are very different from those in China. The history class in China mainly focuses on the history of China and the history of the world, while the history class in the United States actually has no unified teaching objectives and plans. Even in many states, the content of history classes can be decided by teachers themselves. Therefore, in American history class, many teachers spend most of their time talking about the local history of the state and the historical topics they are interested in. In some schools, history is not a course, but many topics related to history, such as African politics, Soviet economy and so on. Students choose topics that interest them. Because the test papers are all given by teachers, they are often imaginative and have no standard answers, so you can make sense, unlike the standardized test papers in China.

Although the content is very different, the essence is similar. First of all, through the study of historical materials, train students to extract information from the materials and form their own opinions. Secondly, through the debate on historical issues, cultivate students' critical thinking ability and tolerance for different opinions. Finally, instill some universal values, such as freedom, equality and the rule of law.
