[Concerns of teachers during school closings: analyzing communication in the twitter-lehrerzimmer regarding opportunities and challenges of digital teaching].

Many schools introduced distance learning as a result of the school closings due to the Corona pandemic in March 2020. Such instruction was often organized digitally without much prior preparation. As a result, an increased exchange between teachers in online communities was to be expected. Analyzing the communication of the online community Twitter-Lehrerzimmer provided insight into topics and allowed to compare topics that were discussed before and during school closings. To identify topics, we applied computational linguistic analysis methods on 128,422 tweets and qualitative content analysis of 270 tweets. The results indicated that topics such as (a)synchronous digital teaching had already been discussed previously but was addressed more often and in more breadth during school closings. The Twitter-Lehrerzimmer was used for mutual support and exchange on urgent challenges such as the availability of high-quality software (compliant with data protection). The results reveal deficits in the German digitalization process from the perspective of teachers using Twitter and show the potential of online communities for information exchange and networking.
