  In this article we report a case study of a Language and Culture-oriented
transdisciplinary XR hackathon organized with Goethe-Institut. The hackathon
was hosted as an online event in November 2020 by our University Lab in
collaboration with Goethe-Institut as a follow-up to our previous co-organized
event within our research group Living Lab. We have improved the formula of the
event based on lessons learned from its previous edition. First, in one of the
two hackathon tracks we provided the participants with a custom VR framework,
to serve as a starting point for their designs to skip the repetitive early
development stage. In cooperation with our partner, Goethe-Institut, we have
also outlined best modern research-backed language-learning practices and
methods and gathered them into actionable evaluation criteria.
