Storyboarding is one common strategy used in teaching young people digital media. This paper argues that in adolescents' literacy practices, they engage in production on the go. The metaphor is described in this paper to put forward the argument that storyboarding can be a retrospective and redundant literacy activity in adolescents' school literacy practices when it is not their inherent practice to engage in a two-step process in digital media production, i.e., design intended to precede production. Drawing on the theoretical underpinnings of New Literacy Studies, this study adopts an ethnographic perspective to gain insights into 10 14-year-old Chinese adolescents' literacy practices in Singapore. Data for this paper were collected over a period of eight months from participant observations, with video-and-audio recordings, semi-structured and in-depth text-elicited group and individual interviews, the adolescents' research diaries and artefacts from their literacy practices.
