Gudykunst提出的焦虑/不确定性协调(AUM)理论对跨文化交际有效性的研究具有里程碑的作用。本文从解剖AUM理论的入手,论证了跨文化交际与课堂教学在本质上的相同属性,并以AUM理论为指导,对课堂教学做了调查,分析了问题,挖掘了原因,提出了对策。这是跨文化交际学与外语教学结合的初步尝试。 Gudykunst’s Anxiety / Uncertainty Coordination (AUM) theory is a milestone in the study of the effectiveness of cross-cultural communication. Beginning with the dissection of AUM theory, this paper demonstrates the nature of the same attributes of intercultural communication and classroom teaching. Based on the AUM theory, it investigates the classroom teaching, analyzes the problems, analyzes the causes and puts forward countermeasures. This is the initial attempt to combine intercultural communication with foreign language teaching.
