For the pre-reader, a comic can be purely graphical in nature and help provide practice with sequencing as well as concrete to abstract transitions using illustrations instead of written words. The written component of a comic can be introduced when the early readers are ready to connect words with images. Comics can help early readers or readers with language acquisition problems by providing visual clues to the context of the narrative.
For more advanced readers, comics can contain all the complexity of ‘normal’ written material which the student must decode and comprehend, such as puns, alliteration, metaphors, symbolism, point of view, context, inference, and narrative structures. A comic can also be a stepping-stone to more complex and traditional written work. A single pane in a comic can represent paragraphs worth of written material in a manner that is enjoyable and effective for the early or challenged reader.
