This paper exemplifies the curricular framework of instructional design in management education at universities. The Magic Cube of eAccounting meets the didactical challenges concerning heterogeneous levels of preknowledge within large-scale accounting classes up to 600—mostly non-native speaking—undergraduate students. Following the Blended Learning approach, the presented pedagogical concept subsumes diverse subjects in the field of accounting and its inclusive adoption in continuative well as comprehensive courses. The applied methodology deals with these multi-dimensional impacts directed by a didactic rationale. The e-Learning architecture shows a universally applicable design and may be customized. The eAccounting project was developed at the Faculty of Business, Economics and Statistics at the University of Vienna and has been implemented in 2008.
