COVID-19 - Open access services for online teaching

Due to the spread of COVID-19, schools are being closed across the board and teachers and pupils are going to have to communicate via the Internet. Here we list free tools that can be used by teachers to create a remote teaching environment for a class.

1. Jitsi Meet

Jitsi Meet is a web application for audio and video conferencing, which teachers and pupils can use for online lessons. Each participant sees a tile view showing the transmissions of others. A click on the Hand symbol allows one to "put their hand up". It is also possible to transmit the contents of the user's screen, or just a single window, instead of the video feed. This allows the teacher to show slides etc. There is also a text-based chat facility via which information such as links can be shared.

Where can I find Jitsi Meet?

Service operation

Teckids e.V. is a non-profit organization in which pupils, educators and computer scientists work together to develop Free Software, not only educational software, but also software useful for supporting educators in their work. Our team are doing their best to expand the services we offer, in response to the current situation. We would particularly like to thank Kirill Schmidt, Benedict Suska, Tom Teichler, Philipp Stahl, Jakob Kirsch and Jonah Döll (ages 10 to 16) for their work.

We welcome offers of support (either financial or practical) where they help to ease the challenges we face.

Should we have sparked your curiosity about providing free and open tools, the team is available via e-mail for presentations and consultations in schools (under normal circumstances -- Jitsi might be a better idea at present).

Support and questions

The team is available from 9 a.m. to 6 p.m. for support requests, via email:
