Flow is a state of total absorption and concentration in an activity that is desirable for students, as it enhances the learning experience. Due to the importance of flow for learning, this research investigates the influence of three flow preconditions--namely balance of skill and challenge, feedback and goal clarity--on students' flow, operationalized as heightened concentration, sense of control and autotelic experience, while using clickers--a type of polling device. The study also explores the impact of concentration, sense of control and autotelic experience on students' perceived learning and satisfaction. Based on a survey of 204 undergraduate students who use clickers in the classroom, the findings show that balance of skill and challenge has a positive influence on students' concentration, sense of control and autotelic experience. Both feedback provided by clickers and goal clarity have a positive influence on concentration and sense of control, but do not influence the autotelic experience. Findings also corroborate the positive impact of concentration and sense of control experienced by students on perceived learning. Finally, autotelic experience predicts both perceived learning and satisfaction.
