The undergraduates have always been perplexed by explanation of Revolution History Paradigm and Modernization Paradigm in the study in Outline of Chinese Modern History. The young want to break through Revolution History Paradigm, and can’t drive Modernization Paradigm freely, so they often make mistakes easily in the cognition of history. The teachers must stick to the right guiding of teaching material, help the undergraduates know the relation of two paradigms, find the lack and questions, raise the ability of the undergraduates’ historical speculation, and achieve the teaching aim of Outline of Chinese Modern History.
