In the next phase, the learning accompanists define their instruction structure and integrate their users into the use of the miTAS app. Together, they create the basis for a cooperative learning environment and deepen their understanding of the app's functionalities. Both groups also improve their skills in using the app - and beyond - through mutual exchange and joint "doing". The media box also provides support in this phase. There can be found in-depth application videos, for example on functions that go beyond simple training.
