The document discusses the importance of integrating language skills - listening, speaking, reading and writing - when teaching English as a foreign language. It argues that teaching skills in isolation, without relating them to each other, leads to rote learning rather than meaningful learning. Learners need comprehensible input in order to produce output, and all four skills should be developed together to mirror real-world language use. The document recommends using techniques like tuning students into activities, providing comprehensible input, and creating natural contexts for communication to facilitate language acquisition.
