English is the most frequently taught and studied language worldwide. There is not only a great diversity of Anglophone language variations and cultures, but there are just as many ways in which the language might be taught in teaching and learning contexts. As a branch of the humanities, Didaktik des Englischen (also known as the Teaching of English as a Foreign Language, TEFL) draws on the findings of key fields such as linguistics, English and American studies as well as other related areas, focusing on the development of critical thinking and promoting intercultural learning. While investigating the conditions and processes of learning and teaching, it constantly examines current topics and new texts. In this regard, TEFL is concerned with theoretical concepts and explores the possibilities of their methodological realization in class.
