Chaos Complexity Theory (CCT) offers a dynamic framework for understanding language learning as a nonlinear, self-organizing process influenced by cognitive, social, and environmental factors. Unlike traditional linear models, CCT emphasizes the unpredictability and adaptability of language acquisition, where small changes in one aspect of the system can lead to significant shifts in learning outcomes. This chapter explores the application of CCT in language learning, highlighting its principles through classroom examples such as dynamic group discussions, interactive problem-solving tasks, and adaptive digital learning platforms. It also addresses the challenges of implementing CCT, including its lack of structure, potential cognitive overload, and difficulties in assessment. While CCT provides valuable insights into the complexity of language learning, its practical application requires balancing adaptability with the need for structured guidance. The chapter concludes with recommendations for integrating CCT principles into language teaching, emphasizing the importance of flexibility, learner-centred approaches, and the role of real-world interactions in fostering language development.
