Abstract:

Videos are gaining an ever growing importance in the learning scenario. Educational movies have been used for more than half a century in schools, but after the millennium turn new ways to use of video technology have emerged. For the new generation, but also for many non digital-natives, it is today normal and obvious to resort to social media, such as youtube and vimeo, for informal learning , This happens at any time and anywhere, thanks to the diffusion of of mobile devices such as the ubiquitous smartphones. On the other hand, Short videos, typically of a maximum of 10 minutes, are an essential ingredient in most MOOCS, where they are interleaved with other activities. Am additional, different type of usage of video as learning aid are recored lectures, which have been here for approximately 20 years, event though their use has become relatively widespread only in the last decade. In this paper we deal this last form of video usage for learning purposes.

In particular, we present an investigation which spans over several years of lecture video-recording usage, discussing the difficulties of introducing this methodology, its effectiveness, possible type of usages and pros and cons rom the points of view of both students and teachers.

We also review what advantage and disadvantages are presented in literature, and compare them with our most recent results.
