随着义务教育阶段新版课程标准的颁布，“大概念”理论愈来愈受到教育研究者的重视。在历史教学领域，“大概念”指居于历史学科核心位置、可以反映历史学科本质、联系学科内部分散知识点的核心概念，对于教师的“教”与学生的“学”有着双重价值。“旧民主主义革命”并非初中历史教学中某一课、某一单元的内容，而是涉及了多个单元，一直是初中历史教学的重点，但也存在概念多、线索杂的问题，大概念教学因其知识迁移、联系琐碎知识点的价值，有助于解决这一系列问题。综合考虑大概念的选取原则，选取“旧民主主义革命”为大概念，进行大单元教学设计，联系从鸦片战争到五四运动共计13个课时的内容，重新构建课程框架，以期克服教育困境，更好地促进历史学科核心素养的培养和立德树人根本任务的落实。

With the promulgation of the new curriculum standards for compulsory education, the "big ideas" theory has received more and more attention from educational researchers. In the field of history teaching, "big ideas" refer to the core concepts that are at the heart of the subject, reflecting the essence of history and linking the scattered knowledge points within the subject, what’s more, the theory is value to teachers' "teaching" and students' "learning". The "Old Democratic Revolution" is not the content of a particular lesson or unit in junior history teaching, but involves a number of units, and has always been the focus of junior history teaching, but there are also many concepts and clues, which “big ideas” theory can help solve this series of problems because of their value in knowledge transfer and linking to trivial knowledge points. The curriculum framework is reconstructed in order to overcome educational dilemmas and to better promote the cultivation of core literacy in history subject and ensure that education performs its fundamental mission of fostering virtue.
