Tools for online teaching

This page gives an overview of tools for online teaching sorted by application type.

Communication and web conferencing systems

Which system should I use?

If you have a web conference or online course with less than 200 participants that involves personal data: use Big Blue Button.

If you have a web conference or online course with up to 300 participants (or up to 500 with a separate licence) that involves lots of videos of the participants: use Zoom.

Big Blue Button

The Communication, Information, Media Centre (KIM) offers a locally hosted system on the basis of the open source software BigBlueButton (BBB). The system and data are kept in the university’s own Data Centre. It can be used as an application in a web browser and can also be integrated into ILIAS.We recommend using the Chrome browser in order to access all of the available functions.

OBS instructions in English from Dr Christian Schmidt in the university’s Department of Biology. Many thanks! You will need to log in using the “My University” icon at the top right of the website first.

Communications and Marketing provides templates for creating screencasts in the university's corporate design.

Please note:  Although OBS recommends *.mkv as the standard setting, we recommend you use *.mp4 instead, since Safari and Firefox browsers cannot open *.mkv files. Alternatively, you can use Handbrake to convert the file before uploading it to the university’s cloud server.

We recommend saving and storing your files on the university’s cloud server. Please note the instructions for integrating the cloud server in ILIAS (tab “collaborative cloud integration”).


You can use screencast-o-matic to make your own screencasts easily. Screencast-o-matic instructions from Dagmar Sorg in the university’s Department of Computer Science. Many thanks!

Tips for Mac users 

You can use the QuickTime Player pre-installed on your device to make audio and screen recordings. Once you open the app, you can click on “File” and then select “New Movie /Audio” or “Screen Recording”.

You can use the pre-installed iMovie app to easily create and edit videos using a Mac/iPad/iPhone device.

Starting with iOS 14, iPhones and iPads can be used to make screencasts: Control Centre settings - add the red app with the circle "screen recording". In the Control Centre (swipe from top to bottom), tap the function to start and end the recording. The videos will be available in the "photos" app.

IMPORTANT: As per General Data Protection Regulation (GDPR), no recordings may be made of web conferences!
