Hybrid Teaching-Scenarios

What do we mean by „hybrid teaching-scenario“?
Generally speaking, “hybrid” means “mixed”, a mixture of on-site and digital lecturing. The concept normally refers to simultaneously teaching on-site and online in one single lesson.

Hybrid scenarios in this sense are technically challenging and do not always make sense, didactically speaking. Thus, lecturers should examine carefully whether they really want to use such a scenario.
Concerning the technical and didactical implementation, differences to traditional lecturing depend on the criteria
  • type of lecture
  • lecture room
  • intensity of interaction
  • and size of group.
Following below, we explain two different scenarios and give technical recommendations.

Scenario 1: Large lecture / little interaction / recording and synchronous transmission

This scenario assumes that while holding an on-site lecture with a high number of participants, the lecture is simultaneously transmitted live to online participants.
In this scenario, the lecture is also being recorded. This is possible with the existing technical equipment in our lecture rooms.
Without the recording students with technical problems or time issues are being excluded. Furthermore, on-site participants cannot re-watch the lecture contents and learn from the recording.  
Generally speaking, in this scenario the recording is more important for the students than participating online via Webex.
  • Interaction of those students participating on-site is possible; the lecturer has to repeat questions and discussions for those participating online, so that these are recorded/transmitted clearly via Webex.
  • Interaction of those students participating online takes place via chat-system. The lecturer or an assisting person has to read the questions aloud for the students in the lecture room.
  • Online participation takes place via Webex. Webex catches the sound of the lecture room microphone, the application released via Webex (e.g. PowerPoint) and (if applicable) the video on the lecturer’s notebook. This means that events only filmed by the lecture room camera (e.g. experiments), are not transmitted via Webex, but they are recorded.
  • For recording the lecture, the lecture room equipment is used. The sound of the lecture room microphone, the lecture room camera and the presentation transmitted to the lecture room beamer are being recorded (not the screen of the lecturer’s notebook).
  • The recording is uploaded in the ILIAS-course.
  • It is recommended that the lecturer is assisted by another person whose responsibility it is to look after the chat.
  • Most lecture rooms with camera are being equipped for this scenario. An instruction document will be issued in time for winter semester. Please refer to our list of lecture rooms (German page) lecture rooms  to determine which lecture room is suitable for this scenario.
  • No investments needed, lecture rooms are equipped for this scenario.

Scenario 2: Small lecture or seminar / lively interaction / synchronous transmission/recording possible

This scenario assumes a lecture in which interaction has a vital role. The one-site lecture is transmitted live in sound and vision, meaning the lecturer and the attending students are captured on Webex. Being able to see and hear the attending students facilitates interaction for those students participating online.
  • Interaction of those students participating on-site is possible as usual.
  • Interaction of those students participating online is possible via Webex-audio or chat-system.
  • It is difficult to moderate a debate with on-site and online participants, and the spontaneity and liveliness of the debate suffers. Thus, it is recommended to alternate between phases of lively on-site discussion, with the online-participants just listening, and phases of discussion with the online-participants.
  • The special camera and further technical equipment will have to be brought to the lecture room and taken back if they cannot be mounted to the wall / attached somewhere permanently.
  • The lecturer has to oversee the lecture room and the Webex-meeting-room at the same time. In order not to miss questions from students online, an assisting person might be useful.
  • Recordings are not really suitable for interactive teaching scenarios. There are strict regulation concerning data privacy: All participants have to agree to the recording, the video may only be published in the ILIAS-course and should be deleted after the course achievement at the end of the semester (e.g. exam). Further requests concerning data privacy are to be made to the data security officer of the University of Stuttgart (
  • Special 180° cameras are needed, as well as additional microphone / speaker-combinations for the Webex-meeting.
  • When recording the lecture using the lecture room equipment in smaller lecture rooms (please refer to lecture room list), only the sound of the lecture room microphone and the presentation are being recorded. The interaction of the participants is not being recorded. This is easier concerning data privacy protection, however it reduces the recording to the lecturer’s inputs.
  • We will provide an instruction document in time for winter semester.
  • When recording from a lecture room / seminar room without recording-equipment, recording will need to take place using the lecturer’s notebook, e.g. with OBS (German page). Everything caught on Webex is caught in the recording.
  • Additional cameras and microphone / speaker-combinations will cost between 1000,-€ and 2000,-€.
  • It is not planned to equip small lecture rooms / seminar rooms. The equipment will have to be brought by the lecturers.
  • It is easier to equip rooms that can be locked after lessons or where camera / microphone / speakers can be attached somewhere.
