Language Walls are Word Walls expanded to a more sophisticated level to include ideas, notions, images, and much more, providing for deeper discussions. Language walls foster both social and academic discourse, allowing the teacher to document specific aspects of language. These walls allow for building vocabulary in all content areas. The focus of a language wall is on language generation by the students which create new information and understanding about the world.
