Structured Abstract Background: The increasing ecological, economic, and social challenges have amplified the demand for Education for Sustainable Development (ESD). A significant challenge in the field of ESD is the absence of universally understood definitions for key terms such as sustainability, sustainable development (SD), and ESD itself. In...

... z-score refers to zero as a represeantative of an overall average. Each frequency from Figure 1 was substracted by the general averageg across all dimensions and the result divided by the standard deviationg of the general average. This z-transformation allows to compare the frequencies of the dimensions with reference to the general average frequency and indicates a relevance of SD in the curriculum. ...

... (in the order of Across all curricula/ occupations "Ecology" is the most frequent dimension (230 counts), followed by "Socienty" (127 counts), and "Economy" (105 counts). Furthermore, the findings show that the SD topics identified in the curricula can primarily be assigned to the dimension "Ecology" in most of the evaluated curricula (Figure 1, Building Services Technician, Electronics Technician, Physics Laboratory Technician and Chemical and Pharmaceutical Process Technologist). Only in the curricula for the occupations of Geomaticist and Road Builder are most SD topics allocated in the dimension of "Society". ...

... overview of the SD dimensions in the curricula is given in Figure 2. For better comparison z-values for each dimension were computed based on the average frequency of the dimensions across all occupations, i. e. all frequencies from Figure 1 were summed up and divided by 18 (= six professions x three dimensions). The grand mean of frequencies is AVGg= 25.67 (SDg= 14.68). ...
