Manga and Comics for ELLs
Since using visuals is one recommended strategy for language teachers, it's no surprise that over at EFL Classroom 2.0, David Deubelbeiss has written about how manga and comics are great tools for educators of English-language learners. He includes a folder of comics materials that teachers have shared with each other.
I wasn't a big comics fan as a child. But as an adult I have read Persepolis and Persepolis 2. They're graphic stories by Marjane Satrapi about her life during and after the Iranian Islamic revolution. Those comic and irreverent (but also sad) stories left a much stronger impression on me than if I'd read an academic book on the subject. They've been made into a movie, but I haven't seen it, as I wanted the powerful medium of the graphic story to stay with me.
