Developing a course suitable for oversea's class meets the needs of cross-cultural communication. The paper uses action research to bring up a teaching model for research-based design, consisting of three steps as initial research, theme transformation, and project design. Through the reflection of teaching practices, the research found that the cross-cultural method plays a critical role in helping students understand the relationship between different cultural contexts and materialistic cultural diversity; the teaching process model, together with process control, secure the teaching effect.
