As part of the lernen:digital project, we have developed the online portal duo (digital and open) of the Tübingen Center for Digital Education: https://duo.tuecede.de/. The portal provides scientifically tested and field-tested materials for the education community and teacher training:

- Compact reports with current research findings on teaching with and about technologies

- Digitally-supported teaching concepts from various subjects

- Explanatory videos

- Training opportunities on digitalization-related topics

The materials are freely accessible and are intended to help explain, enable and exemplify effective teaching with and about digital media.
