Graphic novels can be used in the secondary school classroom as part of a multiliteracies approach to help develop critical literacies of English-language learner (ELL) students. One particular graphic novel, "Maus," is discussed as a possible teaching resource. Intellectually substantive graphic novels that foreground racism and immigrant otherness often resonate with ELL students. These texts' multimodalities along with their engaging content reflecting the diverse identities present in many classrooms work in tandem to help deepen the students' reading engagement. For ELL students, their increased engagement via graphic novels can facilitate their entry and apprenticeship into important social networks that amplify opportunities for academic success in mainstream classes. Reporting from a collaborated pilot study of teaching "Maus" in an ELL high school class, I conclude by examining how it can be used to develop and draw on students' multiliteracies practices.
