Under the title "Learning in the work context – a chore or an underestimated opportunity?", Dr. Julian Decius presented his research on work-related learning upon invitation by Dr. Miriam Schilbach (Leibniz Institute for Resilience Research) at the Institute Colloquium of Psychology at the University of Mainz. The lecture on 16.12.2022 addressed the need for continuous learning and further development of employees in a constantly changing, dynamic working world - both for their own employability and for organizational success. Furthermore, the talk differentiated various forms of work-related learning and presented the degree of effectiveness of learning along different dimensions (such as technology, simulation, or individualization) based on yet unpublished meta-analytical findings. In the further course, a special focus was put on informal workplace learning. Using examples of industrial employees in medium-sized companies, Julian Decius presented the conceptualization and operationalization of informal learning as well as interactions with work demands, resources, and job crafting. Finally, an outlook on a novel conceptual model of "New Learning" including initial empirical validation and discussion of theoretical and practical implications was presented.
