随着海外线上汉语课堂的迅速发展，依托于互联网的国际汉语网络教学平台为汉语的教学与文化的传播提供了弹性的时间与空间条件，满足了汉语学习者语言技能学习的需求，也迎合了汉语学习者了解中华文化的心理需求。在网络中文教学的背景之下，文化教学对于学生全面真实地了解中国发挥着巨大的作用。地域文化教学在文化教学中占据重要的地位，在对外汉语线上教学中，发挥地域文化的作用，能够有效整合地域文化资源，构建具有地方特色的中华文化教学体系，加深海外学生对中国文化的了解，华裔儿童群体因其身份特殊性，地域文化教学也能够在一定程度上加强海外华裔儿童的文化认同。苏州地域文化是中华文化的重要组成部分，且苏州地域文化可运用到教学中的内容丰富，能够吸引学生的学习兴趣，但目前为止苏州地域文化在线上中华文化教学中的应用研究鲜有涉及，因此研究苏州地域文化在线上国际中文教育中的应用具有一定的现实意义和独创性。苏州地域文化教学在文化教学中的应用对于将来想要在苏州留学、来苏州游玩的海外汉语学习者有着积极的促进作用，将苏州地域文化融入文化教学也能够进一步提升苏州这座城市的国际知名度，传播优秀的中华文化。
鉴于此，本文以笔者在优实国际中文学校的线上教学实践为基础，结合苏州地域文化、地域文化教学、以汉语为第二语言的中华文化网络教学研究、华裔中华文化教学相关理论，采用课堂观察法、文献研究法、问卷调查法以及访谈法等多种研究方法，以优实国际中文学校华裔儿童汉语学习者为教学对象，将苏州地域文化融入海外华裔的国际中文教育课堂，设计出有苏州地域特色的文化教学内容，并根据研究数据评估教学效果，反思其教学实践中的不足之处，提出针对性意见。
首先，论文梳理了苏州地域文化，阐述了苏州地域文化的特点及其资源分类。其次，对苏州地域文化课程在优实国际学校的开展做了前端分析，对苏州地域文化课程在优实国际中文学校的开展进行可行性分析。问卷调查和教师访谈的结果表明，开设课程切实可行，笔者就学生问卷调查以及教师访谈建议进行了苏州地域文化的相关教学设计。最后，作者针对开展的苏州地域文化课程从课程相关认可度、课程满意度调查、学生对本门文化课程的感受看法等方面了解学生的评价与反馈，进行教学反思，论文最后提出了在线上文化教学中进行苏州地域文化教学的建议。

With the rapid development of overseas online Chinese classes, the Internet-based international Chinese online teaching platform provides flexible time and space conditions for Chinese teaching and cultural dissemination, which meets the needs of Chinese learners for language skills learning and the psychological needs of Chinese learners for understanding Chinese culture. 
Under the background of online Chinese teaching, cultural teaching plays an important role in students' comprehensive and true understanding of China. Regional culture teaching plays an important role in cultural teaching. In the online teaching of Chinese as a foreign language, by giving play to the role of regional culture, it can effectively integrate regional cultural resources, build a teaching system of Chinese as a foreign language with local characteristics, and deepen overseas students' understanding of Chinese culture. Regional culture teaching can also strengthen the cultural identity of overseas Chinese children to a certain extent. Research on cultural teaching in academic circles has been relatively complete, and some scholars have applied  regional culture to teaching Chinese as a foreign language. Suzhou Regional Culture is an important part of Chinese culture, but so far, there are few applied studies on Suzhou regional culture in teaching Chinese as a foreign language online, and Suzhou regional culture can be applied to teaching rich content. It is of practical significance and originality to study the application of Suzhou regional culture in teaching Chinese as a foreign language online. The application of Suzhou regional culture teaching in cultural teaching will play a positive role in promoting overseas Chinese learners who want to study and visit Suzhou .
