In diesem Artikel werden die Synthese von Thymolblau als Schülerexperiment und passende Augmented-Reality (AR)-gestützte Lernmaterialien vorgestellt. Zudem wird der Kenntnisstand zur Synthese von Thymolblau sowie dessen pH-abhängige Struktur-Eigenschafts-Beziehung vor dem Hintergrund neuerer Erkenntnisse diskutiert und es wird über Erfahrungen mit dem Einsatz des Experimentes in der schulischen und universitären Praxis und im Rahmen von Fortbildungen berichtet.
From employee to expert
(2021)
In the context of the collaborative project Ageing-appropriate, process-oriented and interactive further training in SME (API-KMU), innovative solutions for the challenges of demographic change and digitalisation are being developed for SMEs. To this end, an approach to age-appropriate training will be designed with the help of AR technology. In times of the corona pandemic, a special research design is necessary for the initial survey of the current state in the companies, which will be systematically elaborated in this paper. The results of the previous methodological considerations illustrate the necessity of a mix of methods to generate a deeper insight into the work processes. Video-based retrospective interviews seem to be a suitable instrument to adequately capture the employees' interpretative perspectives on their work activities. In conclusion, the paper identifies specific challenges, such as creating acceptance among employees, open questions, e.g., how a transfer or generalization of the results can succeed, and hypotheses that will have to be tested in the further course of the research process.
Digitizing grocery retailing
(2021)
Multiple emerging technologies both threaten grocers and offer them attractive opportunities to enhance their value propositions, improve processes, reduce costs, and therefore generate competitive advantages. Among the variety of technological innovations and considering the scarcity of resources, it is unclear which technologies to focus on and where to implement them in the value chain. To develop the most probable technology forecast that addresses the application of emerging technologies in the grocery value chain within the current decade, we conduct a two-stage Delphi study. Our results suggest a high relevance of almost all technologies. The panel is only skeptical about three specific projections. As a consequence, grocers are advised to build up knowledge regarding the application of these technologies in the most promising areas of their value chain.
Eine mit digitalen Informationen angereicherte Realität spielt eine zunehmend wichtigere Rolle in unserem Alltag, aber auch im Chemieunterricht. So werden Lehr-Lernszenarien mit Augmented Reality (AR) positive Effekte auf den Wissenserwerb, Motivation und andere Faktoren des Lernens zugeschrieben. Dieser Beitrag gibt einerseits einen Überblick über medienfachdidaktische Gestaltungsparameter und andererseits werden Werkzeuge vorgestellt, um diese Technologie AR-gestütztes Unterrichtsmaterial zu erstellen.
