Mobile devices have sweeping repercussions in education and suggest shifting content-engagement paradigms. Extensive reading (ER) is not unaffected by the many evolving aspects of mobile technology in second language classrooms.

Focusing on those reluctant readers (RRs) this study investigates the basis for disengagement, both with ER and perhaps with mobile technology. Using a post-pilot questionnaire and focus group discussion, the authors attempted to understand reasons behind the disconnect. Key findings for why students neglected this system included: insufficient software training, misconceptions about reading
