Scaffolding remains a secondary work activity in most nations, despite the fact that many tasks on building sites by bricklayers, plasterers, painters and others require elevated working platforms. The vocational training includes not only the technical principles of the craft, but also the safe handling of equipment, correct processes, and prioritising safety on the building site, with scaffolding construction being one of Germany's youngest officially trained trades. The reason for the considerable emphasis on qualification and safety is because falls from height remain the top cause of deaths in the construction business. Aside from the objective of zero workplace accidents, there is a labour shortage, particularly at the entry level in crafts. Thus, the difficulty is to spark young people's interest in craft vocations while simultaneously teaching them in an approachable manner once they begin their apprenticeship. The paper provides insight into the current state of vocational training digitisation, the requirements provided by practitioners, and the concepts underlying the chosen blended learning approach, which includes mixed reality applications. The technical implementation details of the augmented and virtual reality apps are offered, as well as a discussion of technological restrictions. A group of trainees tested the applications as part of a usability study. The report concludes with a discussion of its findings.
