Community Language Learning (CLL) was developed by Charles Curran in Chicago in the 1970s-1980s. It is an approach where students work together in a circle with a tape recorder to develop the language aspects they want to learn. They reflect, have a recorded conversation, discuss what was said, transcribe the recording, and analyze the language used. CLL focuses on learner needs and works well for occasional lessons or with teenagers as it encourages peer learning and correction in a supportive community environment.
