中华人民共和国建立后，随着教育事业的不断发展颁布了多个版本的初中历史教学大纲和课程标准，其内容因国际局势、两岸关系和史学研究等因素的影响不断变化。其中关于抗日战争史教学内容的变化尤为显著，其变化情况可以分为增加、删减和修改几种。 教学内容增加的部分主要集中在国民党领导的正面战场的抗战、日军侵华过程中的南京大屠杀和世界反法西斯战争的介绍等方面。有关正面战场的内容变化主要是由于两岸关系在改革开放后不断向好发展，针对抗战中国民党作用的学术研究不断增多出现的。南京大屠杀的变化十分具体和详细是因为史学研究的不断深入和日本右翼不承认侵华历史等行为造成的。此外随着国际局势的变化，中国不断深化改革开放，意识形态影响减弱，中国和世界的联系加强，世界反法西斯战争的相关内容也不断增加。 国民党统治区的统治、国民党第六次代表大会和世界人民支援中国抗战的教学内容呈减少的趋势。删除这些内容的原因是为了客观全面的介绍抗日战争。强调国民党与共产党的合作，强调中国抗日战争与世界反法西斯战争的关系。 此外，随着两岸关系变化和史学研究的深入，第二次国共合作过程中抗日民族统一战线的领导权问题得到充分的研究，相关内容得以修改，从中国共产党独自领导转变为国共合作共同领导；对国民党、国民政府等的形容词汇也从贬义词为主变为更客观地描述；“十四年抗战”概念也得到明确。 以上，通过对初中历史教学大纲和课程标准中变化情况的总结分析可以知道，国际局势、两岸关系和史学研究直接影响着抗日战争史教学内容的变化。鉴于此，在教学中教师更应主动吸收科学的史学研究成果组织教学内容，采用恰当的教学方法开展课堂教学，向学生传达正确的情感、态度和价值观。从帮助学生构建完整的历史知识体系着手，设计《中华民族的抗日战争》一课的教案，为抗日战争史教学提供实例。

After the founding of the People's Republic of China, with the continuous development of education, a number of versions of the junior high school history syllabus and curriculum standards have been promulgated, and their contents have been constantly changing due to factors such as the international situation, cross-strait relations and historical studies. In particular, the changes in the content of the teaching content of the history of the War of Resistance Against Japanese Aggression are particularly significant, and the changes can be divided into several types: addition, deletion and modification. The increase in the content of teaching content is mainly concentrated on the anti-war in the frontal battlefield led by the Kuomintang, the Nanjing Massacre in the process of Japanese aggression against China, and the introduction of the world anti-fascist war. The changes in the content of the frontal battlefield are mainly due to the continuous development of cross-strait relations after the reform and opening up, and the increasing academic research on the role of the Kuomintang in the war of resistance has emerged. The content of the Nanjing Massacre became very specific and true because of the deepening of historiography and the fact that the Japanese right wing did not recognize the history of aggression against China. With the change of the international situation, China has been continuously opening up, gradually abandoning the influence of ideology, and closely linking China's anti-Japanese war with the world anti-fascist war, and the content related to it has also increased. The rule of the Kuomintang’s ruling area, the Sixth Congress of the Kuomintang and the world’s people supporting the Chinese Anti-Japanese War have shown a decreasing trend. The deletion of these contents is due to the fact that today’s history teaching emphasizes that the War of Resistance Against Japanese Aggression is a national war based on the cooperation between the Kuomintang and the Communist Party. On the other hand, it emphasizes that China’s war of resistance against Japan is part of the world’s anti-fascist war and provides an objective and comprehensive introduction to students. Caused by the history of the War of Resistance. In addition, with the changes in cross-strait relations and the study of historiography, the issue of leadership of the anti-Japanese national united front in the process of cooperation between the Kuomintang and the Communist Party has been fully studied, and relevant contents have been revised, from the independent leadership of the Communist Party of China to the joint leadership of the Kuomintang and the Communist Party; The vocabulary of the Kuomintang and the National Government has also changed from a derogatory term to an objective description; the concept of the "fourteen-year war of resistance" has also been clarified at the national level. Above, through the summary analysis of the changes in the junior high school history syllabus and curriculum standards, we can know that the international situation, cross-strait relations and historical studies directly influence the changes in the teaching content of the anti-Japanese war history. Under the premise of analyzing the reasons for this change, teachers should take the initiative to absorb scientific historical research results to organize teaching content, adopt appropriate teaching methods to carry out classroom teaching, and convey correct emotions, attitudes and values to students in teaching. Starting from helping students build a complete historical knowledge system and a correct outlook on life, values and world views, the teaching plan of the course "The War of Resistance Against Japan" of the Chinese nation is designed to provide examples for the teaching of the history of the War of Resistance Against Japan.
