The aim of this study is to discuss the need for improved intercultural communicative competence (ICC) training for pre-service Chinese as a Second Language (CSL) teachers who travel abroad to teach. Previous studies have shown that pre-service CSL teachers often struggle with intercultural communication, and this study investigates the reasons behind their difficulties and suggests ways to address them. The researchers used the Intercultural Sensitivity Scale (ISS) and the Intercultural Effectiveness Scale (IES) to measure the ICC of 217 pre-service CSL teachers. The study found that while pre-service CSL teachers have strong intercultural communicative emotional ability, their behavioral ability in intercultural communication is weak. In particular, they lacked skills in interactive control, interactive relaxation, identity management, information skills, and behavioral flexibility. The study proposes several strategies to improve ICC training for pre-service CSL teachers. One potential approach is the use of Computer Assisted Language Learning to provide teacher-trainee students with opportunities to practice intercultural communication skills in simulated contexts, receive personalized feedback, and engage with authentic materials and cultural information relevant to their host country. CALL could also facilitate communication between pre-service CSL teachers and former CSL teachers, providing a platform for information exchange and additional psychological support. The study also suggests that pre-service training should distinguish between foreign language learning and intercultural communication skills training. Specifically, it recommends that foreign language proficiency should be improved, while training should focus on educational culture and work culture in the host country, rather than providing a general introduction to the national conditions of the country. Finally, the study proposes that pre-service training should establish contact between pre-service CSL teachers and former CSL teachers as early as possible so that trainees can learn specific relevant information in advance, which can help them get ready, avoid intercultural communication mistakes, and obtain additional psychological support. By incorporating CALL and addressing the areas of weakness identified in the study, pre-service CSL teachers can be better prepared to navigate the challenges of intercultural communication and provide effective and culturally sensitive instruction abroad.
