This instrumental case study examines how adolescent high-intermediate Japanese language learners enrolled in a one-month credited abroad program used video as a mediational tool for (1) learning foreign language, content, and technology skills, (2) cultivating critical multiliteracies and transformative learning regarding geopolitics and the environment, and (3) augmenting their portfolios (Gee, 2004a). Framed in sociocultural and transformative learning theories, this study also suggests that digital video production engaged students extensively in language-based tasks and cultivated collaboration and creativity. Implications suggest future research applying digital video to various languages, levels, and contexts, particularly those in traditional schools and curricula.
