Abstract:Current developments in technology give access to different kinds of online study materials which students use more frequently for exam preparation. However, little attention has been paid to the explanatory videos themselves and how students make use of them. Therefore, the current study investigated the added value of explanatory videos over written study materials and what effect the relevance of a video has on exam performance. A total of 38 students currently or previously enrolled at technical universities in Germany and the Netherlands participated in the experiment. Participants were randomly assigned to one of three different conditions (text only, text and relevant videos, text and non-relevant videos), and compared based on their scores on multiple-choice and open questions. In each condition, participants first started with studying the written study material. Results indicated that participants with text and non-relevant videos performed significantly worse than participants with text only and participants with text and relevant videos. Further, participants with text only did not significantly differ from participants with text and relevant videos. Thus, the results provide evidence that there is no added value of a relevant explanatory video over only a text. However, the study also provided evidence that when deciding to provide explanatory video materials, a non-relevant explanatory video has a detrimental effect on exam performance in comparison to providing a relevant explanatory video or only providing a text. For future research, the design should be longitudinal and involve post-tests to test whether memory or comprehension is investigated.
