Much of the literature one can find on graphic novels and their usefulness for literacy deals with it from a positive position, or simply assumes their use and shows teachers and librarians how to employ graphic novels better. The two areas in which those who argue that comic books are beneficial to literacy in children make their strongest case involve reluctant readers and visual literacy.
In the research, it is argued that graphic novels (along with comic books and even comic strips can be used to help children who otherwise do not read for enjoyment to enjoy picking up books other than those they have to read for school. According to one author, "This revitalized genre has not only saved the day for recreational reading, it has also turned out to be a heavyweight in the teaching of advanced themes in literature and visual literacy."
The benefit of graphic novels here lies in the fact of what they are: a combination of pictures and words. To students who may view the traditional novel as intimidating because of the amount of words on each page, a graphic novel is a welcome change, and the pictures help students understand the text, making language acquisition easier.
Once readers begin to read graphic novels, not only are they actually reading, they are also being introduced to many literary devices and structures such as character development, plot, narrative theme, etc. As defined above, graphic novels are, essentially, novel-length books, just told with a combination of words and pictures.
If we take one example, appropriate for readers in the higher elementary grades, we can see that there exist in well-written graphic novels the themes that are in well written traditional novels. Jeff Smith's Bone series has recently been reprinted (in colour) by Scholastic, a publisher of books for children. In this series we follow the Bone brothers through their adventures as they try to make their way back home to Boneville. In this series of 9 graphic novels, we see the Bone brothers as they deal with hardship and with each other. We follow Fone Bone as he tries to help his new friends. There is an epic struggle of good against evil. While each novel in the series can, to a certain degree, stand on its own, there is an over-arching plot which begins in the first and is only finally resolved in the ninth. A young woman, Thorn, struggles with her identity and her destiny as all of these events seem to revolve around her. And in the end, good prevails and the Bone brothers finally begin their journey home.
These novels, while attractive in their own right as a well designed, drawn and published series of works, are also attractive as a tool for young readers. In fact, Scholastic has published a pamphlet around these books which pushes their usefulness (and the usefulness of graphic novels in general) for students and teachers.
Not only can and do graphic novels have such literary themes in them, but they can also be used, judicially of course, to illustrate religious or spiritual themes as well, those issues and ideas that are important in and to life. In the preface to his book Holy Superheroes!, Greg Barrett writes that "with comics we're also dealing with some powerful myths, stories that express a truth somehow beyond rational meaning." There is a trend, Barrett writes, in our society to find more and more expressions of faith and spirituality even in the more 'pop' art, and "this trend makes comic books—where good and evil, right and wrong, justice, mercy, and the power of love have long been important themes—a terrific place to look for revelation". This makes graphic novels an attractive tool for teachers to get reluctant readers not only interested in reading, but also exposed to important themes and devices in literature.
While engaging reluctant readers is one of the great advantages which people point out with respect to graphic novels and literacy, this is not the only one, nor does it seem to be the most important. Many writers on this topic argue that graphic novels and even comic books and strips aid students with visual literacy, "a group of vision competencies a human being can develop by seeing and, at the same time, having and integrating other sensory experiences", or the ability to 'read' images and understand what they are 'saying.'
This type of literacy is important for students to master as in this technological age almost everything comes at students by means of or incorporating images in some way. With television, advertisements, internet and now even pictures delivered through cell phones, it is important that students learn to understand and interpret not only text, but also images. Comics help with this skill as "comic images enhance and extend the text communication. They attract the attention of the reader and create understanding of unknown factors in the text's language". Thus comics can have a place in the classroom to help students deal with the interplay between the text and the images, as they are more closely connected than those in picture books, and they quite transparently demand this visual literacy to be read.
Graphic novels assist in the procurement of visual literacy since there is, generally, the valuable interplay between the pictures and the text: the pictures may give context to the words themselves, but the words are used in understanding what is going on in the pictures. There are, of course, varieties among graphic novels of amount of text used, but when there is an appropriate amount of text for a student to deal with, this aids in comprehending what is going on.
There are as well some students who will learn better through visual literacy than through traditional text-based methods—using spatial intelligence to learn. Such students may have difficulty with traditional texts because they tend to think pictorially rather than verbally or textually. With students such as these, they can learn to extend their knowledge and skills through comic books: "with some students, pictures combined with text, such as in comic books, are extremely useful in facilitating this extension because they combine the immediacy of images with narrative continuity". This combination aids such students in a number of ways:
The engagement of more than one processing mode, words and pictures, allows better memory and help bring the interpretive skills students do have to bear on the unfamiliar media... This, in turn, leads to new neural connections (as in all learning), but, rather than having to start from scratch, rearranging their thought processes, students build on abilities already present.
