Drawing upon research on narrative and speech styles and on digital and multimodal communication, the author proposes multimodal narrative discourse analysis (MNDA) with associated pedagogical and analytical procedures to teach and study storytelling. The second language (L2) students first participated in multimodal narrative simulations in the virtual world of Second Life. The university students then presented, evaluated, and revised stories in both face-to-face and digital contexts through multiple modalities and technologies. MNDA further provided tools and methods for analyzing the students' discursive processes and agentive experiences of L2 storytelling. The results of MNDA showed that the proper use of narrative elements, discourse structures, and stylistic devices, as well as bodily, visual, and video resources, assisted the students in developing multimodal designs and storytelling styles. This technology-mediated discourse approach to L2 storytelling suggests the importance of teaching and researching broader narrative contexts and activities other than simply elocution in multimodal communicative activities.
