A General Scheme for a Heterogeneous Manifold of Transitions.

A general praxeological scheme is applied to express relations between praxeological blocks depending on the goal of the analysis and the specific institutional setting within which a mathematical praxeology is considered. Besides its heuristic function, the scheme provides a framework for context dependent categorizations of praxeologies. The poster exemplarily illustrates the application of the scheme to two different contexts: measures supporting students in their first year of study; the use of mathematics in engineering sciences.
