AD> The teaching of culture and interculturality is today viewed as an integral part of foreign language education. This book presents insights from recent research on the role of culture in second/foreign and heritage language education. It contains 14 chapters including an introductory chapter that discusses diachronically the evolving notion of culture and how the sociocultural view of culture as a complex and dynamic concept informs language teaching and language learning research. The chapters following the introduction are organised in four parts focusing on: 1) the teacher's role in integrated language and culture learning; 2) the interrelationship between culture, identity, and language learning and use; 3) the effect of culture on learner characteristics which impact language learning processes and outcomes; and 4) curriculum development aimed at fostering language and culture learning. The chapters in Parts 1 to 3 present contributions from current research - either in the form of the authors' original studies or comprehensive reviews of relevant essential research - which bears important implications for curricular practice in foreign language and language teacher education. This close link between research, theory and practice is also maintained in the two chapters in Part 4, which present developmental projects based on well-grounded theoretical frameworks.
