Mobile devices have increased exponentially in the past decades and the rapid development of digital technology has provided rich soil for the growth of mobile learning (m-learning), which is a more convenient means of learning because of no limitations of space and time. Applying the stimulus-organism-response (S-O-R) framework, this study explores how learners experienced flow during m-learning and how their flow experience led to their continuance intentions for m-learning. With an online survey of 270 valid respondents, the model used in this study was validated by the partial least squares method. The results show that two key characteristics of m-learning applications are positively related to flow experience, of which concentration, in particular, rather than perceived enjoyment, plays an important role in continuance intentions. The S-O-R framework offers an overarching way to explore the influences of m-learning application characteristics (stimuli) on learners' evaluations of their m-learning processes (organisms), which further influence their continuance intentions (responses).
