Abstract
This text is based on the Romo’s thesis (2009), the center of which being the place of mathematics in three projects belonging to mathematics training for prospective engineers. Learning involves solving linear differential equations with constant coefficients, equipped by the Laplace transform, the last phase (determination of the original) having two variants (with or without convolution). The didactic transposition is partly determined by the aims of teaching (learning effects are the goal, but other influences are critical and, in a course of vocational training, we may not neglect the institutional references. The computer resources available today raise the question of praxeology really useful : What knowledge is empowering management of parameters and interpretation of software outputs ? What is the contribution of elements of knowledge for effective use of treatment by simulation ?
