Can videos replace instructors in their learning?

navigation

Purpose of videos in teaching

Videos are a useful addition to courses or can also replace them.

Compared to text documents, videos often make learning easier if what is seen and heard can be memorized better than the written text.

Internal platforms and websites should be used to provide the videos. Publication on platforms such as YouTube should be avoided, as the legal requirements could be violated (see YouTube conditions of use, Section 6.1 K)

Usage scenario

Important: More than 15 minutes viewers cannot process each video sequence, attention decreases.

Videos for refresher / exam preparation

Videos that are used to accompany a face-to-face event and are used, for example, to prepare for exams, can be kept comparatively simple.

The focus of these videos is more on the pure passing on of knowledge. Often it is sufficient to transmit the presentation or the board picture combined with the recording of the speaker's sound.

Advantages:
  • Little focus on audio / video synchronicity
  • No additional camera technology required
  • Little effort in post-processing
Disadvantage:
  • A lack of facial expressions and gestures can reduce the listener's attention.
  • Live experiments and impressions of what is happening in the classroom are missing
  • Regular re-production due to changed course content, lecture structure, etc.

Video instead of face-to-face events

If videos are to completely replace the face-to-face event, the event atmosphere should be reproduced in the video as well as possible. In addition to the image of the speaker, the overall situation in the room is also important. Furthermore, the presentation and audio channel must also be transmitted. It makes sense to add additional added value to the video, such as links, short tests or explanatory texts.

Advantages:
  • Reusable self-learning modules
  • Possibility to access the learning content outside of the course offerings
  • No annual re-production necessary
Disadvantage:
  • High focus on audio / video synchronicity
  • Comparatively high processing effort for first-time production
