Traditionally, the content of English language teaching was conceptualised in four skills: listening and reading (receptive skills), speaking and writing (productive skills). More recently, the categorisation of language knowledge and performance has changed: Now the use of our own language, e. g. when mediating, is also taken into consideration and the scope of our lessons is extended by teaching a combination of reading, viewing and listening (audiovisual skills, cf. chapter 6 in this volume).
