What Students Do While You Are Teaching – Computer and Smartphone Use in Class and Its Implication on Learning

The presence of mobile devices (e.g., smartphones, tablets and computers) in the classroom gives students the possibility of doing off-task activities during lectures. The purpose of this mixed-method field study was to learn more about students' behaviors, reasons, and opinions regarding such activities and their consequences on learning. This study is one of few to take a holistic view on this topic by taking the use of all technical devices in class into account and assessing its con-sequences on learning objectively. This is important to gain a full picture concerning the conse-quences of off-task activities in class. Right after a lecture, bachelor students (N = 125) answered a survey containing questions on their usage of mobile devices during this last class. Further-more, they took a test on the content of that lecture. Qualitative and quantitative analysis of data revealed that students spent an average of more than 19% of their time using a digital device for non-class purposes. Interestingly, this was not significantly linked with learning, although many students reported being aware of this behavior's potential negative consequences. But there was a significant negative link between the number of received notifications and learning. These results suggest that external interruptions have a stronger negative effect than internal interruptions, allowing us to make better recommendations on how to use electronic devices in the classroom.
