## 4 CILS Framework: Enhancing Cross-Cultural Language Learning  
### Cultural Sensitivity and Adaptability  
#### 4.1.1 Application of Communicative Competence Models  
The effective application of communicative competence models within the CILS emphasizes the necessity of functional language use in diverse cultural contexts. [PERSON] and [PERSON]'s communicative competence framework, which includes grammatical, sociolinguistic, discourse, and strategic competence, forms the basis for developing CILS's pedagogical strategies. This comprehensive approach ensures that learners acquire language accuracy and gain proficiency in using the language appropriately in various social situations [25].  
In the CILS, grammatical competence involves the mastery of syntax, morphology, and phonology, which is achieved through AI-driven adaptive exercises that respond to the learner's immediate linguistic needs. Sociolinguistic competence, which requires understanding the social mechanisms of language use, such as register, styles, and cultural nuances, is developed through scenario-based learning. These scenarios are crafted to reflect real-life interactions across different cultures, providing learners with opportunities to practice language in its cultural context [26].  
Discourse competence, the ability to connect ideas and form coherent texts, is fostered through interactive dialogues and extended communication practices facilitated by the AI system. These practices encourage learners to use language in extended discourses, enhancing their ability to construct coherent narratives or arguments in the target language.  
Strategic competence, which involves using communication strategies to overcome potential language breakdowns, is critical in intercultural communication settings where misunderstandings are more likely. Figure 4 depicts the improvement in cultural competence among learners using the CILS, categorized by different skill areas. The CILS incorporates tools that teach learners to use paraphrasing, circumloution, and other communicative strategies to maintain communication flow despite linguistic knowledge gaps.  
Figure 4 illustrates the performance outcomes of learners using the CILS. Data were generated from a series of controlled tests conducted over a six-month period, involving participants from diverse linguistic backgrounds. These tests were designed to evaluate the practical application of the CILS in real-world language learning scenarios, measuring both linguistic progress and cultural competence acquisition.  
By integrating these four competencies into the CILS framework, the system teaches language as a set of rules to be memorized and as a dynamic tool for effective and appropriate communication. AI's role in this context is to provide personalized language learning experiences and simulate complex social interactions, making the learning process deeply immersive and practically valuable. This approach ensures that learners are not merely linguistically competent but are also equipped to navigate the intricacies of communicating across cultural boundaries, thus preparing them for the real-world challenges of global interaction.
