Here is an abstract of an article, which I found very interesting.
“Four different settings were studied: three were e-learning environments—with interactive video, with non-interactive video, and without video. The fourth was the traditional classroom environment. Results of the experiment showed that the value of video for learning effectiveness was contingent upon the provision of interactivity. Students in the e-learning environment that provided interactive video achieved significantly better learning performance and a higher level of learner satisfaction than those in other settings. However, students who used the e-learning environment that provided non-interactive video did not improve either. “
Zang et al., (2006) Instructional video in e-learning: Assessing the impact of interactive video on learning effectiveness, Information & Management, vol. 43; pages 15–27
My view is that videos which are not interactive can be effective learning tools too . It is more about how they are integrated in the learning and teaching practices that makes the difference. Still, testing students’ reponces is the way forward.
