The Whole Language theory was created in the 1980s to teach children to read but was later applied to foreign language learning. It emphasizes teaching language as a whole through authentic activities rather than dividing it into separate components. While some see it as an approach and others as a philosophy, research shows it is mainly considered an approach that teachers can implement in different ways based on their students' needs. Whole Language focuses on using real-world materials and authentic contexts to facilitate collaborative, student-centered learning.
