Resumen
The EEdnaS study ?Development and testing of digitally enriched science-related subject matter teaching in digital teaching-learning labs and university classrooms? aims to promote the professional competencies of prospective teachers that are needed for teaching science content in a world shaped by digitalization. To achieve this goal, university teaching units (seminars) that directly address cognitive components of a teacher?s professional competencies, which are important to teaching science content in primary school education, were developed. In addition, prospective teachers were asked to plan, implement, and evaluate primary school science education with a particular focus on digitization, as well as sharing the developed units as open-educational resources. This article reports on the impact of the first part of the seminar concept, in which the promotion of digitization-related, subject-specific teaching methodology, as well as content-related knowledge (TPaCK) was systematically promoted. In a standardized survey, it could be shown that the prospective teachers demonstrated positive developments, particularly in the components PCK, TCK, TPK, as well as TPaCK, regarding the self-efficacy in cognitive characteristics about one?s own ability within the reference frame of self. Furthermore, the development of knowledge, especially in the areas of TK, PCK, TCK, and TPK, could also be determined, but not in relation to TPaCK itself.
