The document discusses two dimensions of writing: consolidatory writing and free writing. Consolidatory writing reinforces oral skills through controlled exercises focusing on grammar, structures, and rhetorical patterns. Free writing focuses on the creative use of language to communicate ideas through free compositions and experiences like personal notes, letters, narration, description, and argumentation. It provides examples of fully controlled and guided writing activities for consolidatory writing, which involve substitution, transformation, and rearrangement exercises, as well as examples of free writing experiences.
