This entry explores the intersection of metacognition and data-driven learning (DDL) in language education. It illustrates how the integration of metacognitive strategies within DDL frameworks significantly enhances the efficacy of learning processes by enabling learners to better understand, regulate and direct their own learning experiences. The core argument of the chapter is that metacognitive awareness—comprising both knowledge of one’s cognitive processes and the ability to regulate them—empowers learners to utilize DDL more effectively. This integration fosters a personalized, reflective and ultimately more effective learning environment. This chapter proposes the benefits of this synergistic approach include improved autonomy, critical thinking and deeper understanding of language use. Additionally, practical strategies for teachers to implement this integrated approach in classroom settings are discussed, highlighting the role of technology and collaborative learning in enhancing metacognition and DDL practices.
