随着中国在世界范围内的影响力越来越大，“汉语热”在世界各地流行起来，“一带一路”的共同发展政策提出后，以越南为代表的东南亚国家进一步加强了和中国之间的政治、经济、文化等各领域的交流。近两年由于全球性新冠疫情等不可控因素，线上汉语教学开始蓬勃发展，逐渐成为汉语国际教育的主流方式之一，但与此同时线上教学也面临着各种新的问题，这都需要一一解决。随着汉语学习需求的扩大，国内外学者也开始探索适用于线上汉语教学的模式。汉语不同于越南语，其发音和书面文字系统均具有极大的特殊性，和汉语相差很大，这使得很多传统的汉语口语教学法急需调整。 本研究立足于中文路的线上汉语口语课程，总结了前人对于情境教学法、线上汉语教学、汉语口语教学的相关成果，在此基础上进行归纳总结，同时结合笔者在中文路的教学实践，充分论证了情境教学法应用于汉上汉语口语教学的可行性。 本研究选取了两个具体的课堂案例，将情境教学法运用其中进行了教学设计，分析了在线上教学的条件下，怎样在不同的课堂教学环节使用情境教学法才可以达到更好的教学效果。经过分析，主要得出了以下结论：第一，情境教学法能够让学生尽快地进入目的语教学环境中，激发学生学习兴趣，并且使用情境教学法受限比较少，所以情境教学法适合汉语口语教学。第二，教师要以授课内容为重点，用情境教学法辅助教学，要根据教学目标、教学内容等合理、灵活使用情境教学法，创设贴近实际生活的情境。第三，越南深受中国文化的影响，越南学生对中国文化的认可程度和接受程度较高，且学生们都具有强烈的学习动机，因此情境教学法也适用于越南成人汉语学习者。 本研究对教师和学生进行了访谈，由此可知情境教学法深受学生们的喜欢，可以有效地减少他们开口表达的焦虑感，将所学知识运用到实际生活中去。教师们也表示情境教学法得到了学生的青睐，降低了学生开口表达的紧张感，顺利地完成了课堂教学任务，成功地实现了教学目标。有关情境教学法在汉语口语教学中的具体实施情况，本研究也从多方面提出了建设性的意见。

With the increasing international influence of China in the world, the “Chinese language fever” has gradually become popular around the world, and after the "The Belt and Road" common development policy was proposed, Southeast Asian countries, represented by Vietnam, have further expanded their exchanges with China in various fields such as politics, economy, science and technology, and education. In the past two years, due to uncontrollable factors such as the global new crown epidemic, online Chinese language teaching has started to flourish and gradually become one of the mainstream methods of Chinese international education, but at the same time, it also faces various new problems. As the demand for Chinese language learning expands, scholars at home and abroad have begun to explore models applicable to online Chinese language teaching. Chinese is different from Vietnamese in that its pronunciation and written writing system are extremely special and different, which makes many traditional methods of teaching spoken Chinese in urgent need of adjustment. This study is based on the online spoken Chinese course of Chinese Road, summarizing the results of previous work on situational teaching method, online Chinese teaching and spoken Chinese teaching, and combining the author's teaching practice in Chinese Road to fully demonstrate the feasibility of situational teaching method to the teaching of spoken Chinese on Chinese. In this study, two specific classroom cases were selected, in which situational teaching method was applied to the teaching design, and how to use situational teaching method in each teaching session to achieve good teaching effect in online teaching environment was analyzed. After analysis, the following conclusions are mainly drawn: First, the situational teaching method can make students enter the target language learning environment quickly and stimulate their interest in learning, and the use of the situational teaching method is less restricted, so the situational teaching method is suitable for teaching spoken Chinese. Secondly, teachers should focus on the content of the lesson and use situational teaching method to assist teaching. They should use the situational teaching method reasonably according to the teaching objectives and the teaching content, and create a situation close to the real life. Third, Vietnam is deeply influenced by Chinese culture, and Vietnamese students have a high degree of recognition of Chinese culture, and they have a strong motivation to learn, so the situational teaching method is also applicable to Vietnamese adult Chinese learners. Interviews with teachers and students in this study showed that situational teaching method was well received by the students and was effective in reducing their anxiety about speaking up and applying what they had learned to real life situations. The teachers also indicated that the situational teaching method was favored by students, reduced students’ tension in oral expression in the test, and successfully completed the classroom tasks and achieved the teaching objectives. This study also provides constructive suggestions about the practical application of situational teaching methods in teaching spoken Chinese from various aspects.
