Can heiCONF and heiCONF-Audimax be used for teaching?

heiCONF and heiCONF-Audimax can be used for live teaching as well as for work-related collaboration. However, for the summer semester, it is recommended, especially for larger courses (> 100 participants), to largely refrain from synchronous teaching (live transmission) and to teach asynchronously instead, that is, by using video recordings.

This can include conventional videos as well as recorded PowerPoint presentations with an audio track. This asynchronous approach safeguards the bandwidth of the entire data network and at the same time offers students greater flexibility when faced with health, private or technical difficulties. The heiCAST service is available for streaming video recordings for teaching purposes. Lectureres can use the new Moodle platform to manage their own teaching videos.
