The document discusses the difference between tasks and exercises in language learning. It states that a task is a communicative activity that requires learners to use language for a non-linguistic outcome, focuses on multiple skills, and aims to simulate real-world scenarios. An exercise, on the other hand, has a restrictive focus on a single language element and aims for a linguistic outcome. Exercises are more controlled and guided by the teacher, while tasks provide more freedom for learners. Examples of both tasks and exercises are also included.
