Contrary to the two performance measures above, the ratings of flow experience revealed a rather different pattern, which may suggest the distinctive nature of a mobile learning experience, and also the benefits of playful game-based learning. “Learning control” asks whether a learning activity encourages exploratory behaviors, with the expectation that learners who experienced feelings of control over learning activities would give a higher rating. “Attention focus” is another sufficient condition for achieving flow experience, being narrowed to a limited stimulus, so higher ratings on these questions mean more engagement in learning activities.
