Digital storytelling has made its way into second language classrooms due to its great potential in promoting linguistic and non-linguistic outcomes increasingly recognized by second language educators. However, the links between digital storytelling and second language learners' willingness to communicate still remain largely unknown. The present thematic review first presents an introduction to digital storytelling and then elucidates its critical roles in promoting second language willingness to communicate traced to four aspects: creating ample opportunities to practice the second language, negotiating aspired identities, engaging learners with cultural and multimodal resources, and constructing communities of shared interests. Finally, directions for future research are discussed.
