This paper presents four theses on virtual classroom teaching and learning that are discussed critically. We use existing theoretical insights extended by empirical evidence from a survey of more than 850 students on acceptance, expectations, and attitudes regarding the positive and negative aspects of virtual teaching. The survey responses were gathered from students at different universities during the first completely digital semester (Spring-Summer 2020) in Germany. We discuss similarities and differences between the subjects being studied and highlight the advantages and disadvantages of virtual teaching and learning. Against the background of existing theory and the gathered data, we emphasize the importance of social interaction, the combination of different learning formats, and thus context-sensitive hybrid learning as the learning form of the future.}, language = {en} } @incollection{UllrichGronau2020, author = {Ullrich, Andr{\´e} and Gronau, Norbert}, title = {Time to change}, series = {Proceedings of the International Conference on Innovative Intelligent Industrial Production and Logistics}, booktitle = {Proceedings of the International Conference on Innovative Intelligent Industrial Production and Logistics}, editor = {Panetto, Herv{\´e} and Madani, Kurosh and Smirnov, Alexander}, publisher = {SciTePress}, address = {[Erscheinungsort nicht ermittelbar]}, isbn = {978-989-758-476-3}, doi = {10.5220/0010148601090116}, pages = {109 -- 116}, year = {2020}, abstract = {Industry 4.0 leads to a radical change that is progressing incrementally.

The purpose of this paper is to propose a theory-based knowledgedynamics model in the smart grid scenario that would provide a holistic view on the knowledge-based interactions among smart objects, humans, and other actors as an underlyingmechanism of value co-creation in Industry 4.0. A multi-loop and three-layer - physical, virtual, and interface - model of knowledge dynamics is developedby building on the concept of ba - an enabling space for interactions and theemergence of knowledge. The model depicts how big data analytics are just one component inunlocking the value of big data, whereas the tacit engagement of humans-in-the-loop - theirsense-making and decision-making - is needed for insights to be evoked fromanalytics reports and customer needs to be met.}, language = {en} }
