"This research monograph presents the concept of "ocupational practice" as a possible common denominator across different educational levels and systems, academic disciplines and countries. The total of 13 contributions were written by highly esteemed international researchers from various disciplines and countries. The guiding principle of the volume is to capture TVET, professional and higher education not over the divide, but through what they share in common, which is the connection of teaching, learning and working. This approach does not aim to negate differences, but to condense what is expressed in multiple dimensions of teaching and learning for an occupational practice. The approach of "occupational education", based on this concept, could become a central leitmotif that can bridge the educational world to the world of work across disciplines, levels, systems and countries. Such a boundary object is missing so far. I welcome and appreciate this comprehensive and comparative approach because it asks the fundamental question - what is the pattern that connects? I can confirm what the editor notes: This research monograph is suitable to open the ground for a possible new area of education."Prof. Dr. Dr. h.c.
