Distraction versus learning with mobile devices in the classroom and student success
We examine the effect of allowing smartphones into the classroom on student performance. We collaborated with a school in China and randomly allocated students taking Chinese verbal into three experimental conditions during one lecture: smartphone banned; smartphone allowed at will; smartphone allowed at will and used to assist instruction. We measure performance gain by the difference in scores in tests taken at the beginning and at the end of the lecture.

Allowing smartphones into the classroom at will reduced the performance gain by 39% of a standard deviation compared to when they were banned from the classroom. However, allowing the devices into the classroom at will and using them to actively assist instruction increased the performance gain by 49% of a standard deviation. These results are driven by students with already good grades and by students in IT majors.

We use video feeds of the lectures to code the time students spent learning and distracted, both on and off the smartphone. Students spend a similar amount of time distracted across all experimental conditions and thus the relative time that students allocate to distraction and learning during lecture does not predict performance. Instead, the relative time spent distracted and learning on the smartphone is what matters. The increase in the performance gain when smartphones are used to assist instruction comes from students spending a larger percentage of the time learning during the lecture learning on the smartphone. Implications for teachers and schools to cautiously allow smartphones in the classroom are discussed.
