Hybrid Teaching

Scenario A ~ presenting

The course primarily has a presenting character, takes place on-site, and is broadcast online via live stream or web conference. The focus is on transmitting the instructor's audio/video/presentation online. A direct verbal exchange between on-site and online participating students only occurs to a limited extent here. The level of interaction is low. This scenario is easiest to manage for large groups.

Further Scenario B ~ interactive

The simplest form of scenario A is shown here: Only the audio/ video/ presentation slides of the instructor is broadcasted online, the online participating students only communicate via Chat

Choosing the appropriate technology for Scenario A

Depending on how complex you want to make the scenario, for example, if you also want to transmit the contributions of those present on-site online, a different technical hardware setup is necessary. Refer to our overview for choosing the appropriate technology .

Image and sound of lecturer only are transmitted online (can be implemented with setup 1, 2, 3 – see overview above)

If you choose the technically simplest setting: online transmission of video and audio only from the instructor & online participants participate only via chat.

  • The instructor should repeat all contributions of the students before reacting to them (no matter if they come in via chat or on site in the lecture hall) so that the other group can hear them.
  • The fact that the two groups cannot hear or see each other makes it difficult to develop a sense of cohesiveness. Online participants in particular may feel isolated. Only the students participating on site have a “lecture hall feeling” here. Thus, the instructor should try a rotation principle so that all students have the opportunity to be on site in the lecture hall at some point during the semester.
The speeches of those present on site are also transmitted online (can be implemented with Setup 1, 2 – see overview above).

If you use additional microphones to transmit the spoken contributions of those present on site to the web conference.

  • Check the hygiene regarding the passing on of the microphone!
  • To avoid walking around the room to pass on the microphone, you could try a wireless microphone, for example, the “Catchbox” wireless microphone.
  • If you want to record the class:
    • Alternative 1: Obtain the students' consent to include their requests to speak in the recording.
    • Alternative 2: Cut out what they say and replace it with text overlays in the recording.
    • Alternative 3: If students do not want it to be recorded, arrange with them that they say shortly before you start to speak. In this case, you will have to repeat the contribution and edit out what the student says later.
Not only sound, but also images of those present on site are transmitted online (can be implemented with Setup 2 – see overview above).
Not only sound, but also images of those present on site are transmitted online (can be implemented with Setup 2 – see overview above).

If you also transfer the video image of the students present on site to the web conference.

  • Discuss this with your students beforehand in terms of the advantage of being able to see each other. (In case of a recording, consent is required in any case!).
  • Set up the camera in the room in a way that there are also areas that are not covered by it so that students who do not want to be visible on the video image can sit there.
  • In the spirit of the principle of equality, you should also ask the students participating online to turn on their camera when they speak or at least to store a profile picture in the web conferencing system. The video tiles of the “onliners” should then ideally also be shown in the room via the projector.
  • This variant can be the most elaborate, but is most likely to provide a certain “lecture hall feeling” for both groups of students.

In principle, this is a setting that we would almost consider an interactive “Scenario B.” Therefore, feel free to take a look at our information regarding scenario B ~ interactive .

When is a Panopto webcast suitable? When is a Zoom web conference suitable?
  • If the focus is on holding a classic lecture that is to be recorded in high quality video (e.g., when blackboard writing or very detailed slides are used).
    • Students should have the opportunity to follow the lecture live (on-site and online) and/or watch it as a recording.
    • It is NOT designed to make the event interactive or to answer questions ad hoc.
  • When the number of online participants is too large for the web conferencing system.
  • As long as any form of interaction is envisaged, i.e., students can ask questions live, either via chat or request to speak
What should you know about the Panopto webcast? What should you know about the Zoom web conference?
  • The live stream is automatically recorded during a Panopto webcast and is directly available online on the Panopto platform after completion.
  • The live stream can demand a lot of computing capacity from the laptop running the webcast. A stable Internet connection (preferably via LAN) is also recommended.
  • No spoken exchange is possible between online participants and on-site participants (teacher & students).
  • Exclusively suitable for the simplest form of scenario A: only online transmission of video/ sound (+ presentation slides) of the lecturer and feedback from online participants via chat.
  • As a “question channel,” students participating online can use the “discussion” function in the Panopto player, or you can provide your students with another chat tool in parallel for this purpose.
  • HOWEVER: a good handling of queries from online participants is only possible to a limited extent, because:
    • On the one hand, there is a time delay of about 40 seconds between sending and receiving a webcast. This makes it difficult to ask and answer questions ad hoc.
    • On the other hand, a chat running in parallel on the presentation laptop is difficult to see when a webcast is in progress.
    • Targeted question slots could help here: deliberately build in several input breaks and only in these can questions be asked.
  • The number of participants for a Zoom meeting is limited to 300 for the TU campus licence. If you need a separate licence for more participants, please contact the HRZ Service.
  • The transmission and recording quality of a Zoom meeting is worse than that of a Panopto webcast.
