Research on IT integration into teaching is an interdisciplinary field that has both educational (didactics) and informatics components. In particular, the situation with the Covid 19 pandemic has forced a push to address personal IT support for teachers in distance education. However, this runs into the problem of the lack of personal educational software, so that in practice the teacher has to adapt to existing technology and test how it can be used for teaching. In this context, the work of a university teacher requires the mass creation of educational content, its transfer between offline computers (laptop, classroom computers) and online environments (web, virtual learning environments, academic information systems, clouds, networks). Given the nature of university teaching, IT support solutions for self-study also face a challenge. However, no single technology covers such a broad scope, so there is a lack of universal solutions. The authors minimize this gap by programming universal software tailored to the needs of the teacher and by building a combined offline/online IT infrastructure on which to conduct the research. Collaborative research by an international team using the infrastructure is a solution to automate the creation of educational packages, including the multi-lingual support. The article clarifies the categories of barriers that the team had to overcome, either from a didactic or an informatics perspective. Here, a new paradigm using a specific data structure (called virtual knowledge) for the rapid reduction and concentration of educational content was proven to simulate virtually any teacher activity. Therefore, the goal of further research is to use the results and experiences to date to build a multilingual learning portal.
