This document discusses integrating the four language skills of listening, reading, speaking and writing. It defines the integrated skills approach as interweaving the skills for optimal communication, unlike the traditional segregated approach. It describes two basic models of integration - simple integration within the same medium, and complex integration through a series of linked activities. Five models for skills integration are then outlined: content-based instruction, task-based language teaching, theme-based teaching, experiential learning, and using episodes. The document concludes that the integrated skills approach exposes learners to authentic language use and promotes learning real content over isolated language forms.
