Information gap principle in communicative English?

The information gap principle in communicative English refers to the idea that effective communication occurs when one participant has information that the other does not. This principle encourages interaction by prompting speakers to ask questions, share details, and clarify misunderstandings, thereby fostering a more dynamic exchange. Activities based on this principle often involve tasks where learners must work together to fill in missing information, enhancing both their language skills and collaborative abilities. Ultimately, it emphasizes the importance of context and participation in the learning process.
