This presentation will report on the initial stages of an ongoing pilot test of X-Reading? (), a new learning management system (LMS) devoted specifically to extensive reading at a private university in Tokyo, Japan. Participants in this study have access to a virtual library of graded readers and are being explicitly asked to read on their mobile devices. This paper reports on pre-pilot questionnaire data and it compares students’ word-per-minute and reading comprehension tests scores for reading on their personal mobile devices and a paperback book. Readers can learn about the implementation of X-Reading? in a university ELF program, reflect on student attitudes towards reading digitally and consider the challenges in implementing a digital extensive reading component whereby students are asked to read on their personal electronic devices.
