How is this activity developed? When we face a real problem we translate it into mathematical language (modelling). We solve the resulting mathematical problem to obtain the mathematical solution (simulation). The analysis of the results allows us to extract information from the real problem. If the interpretation of the results does not fit with the real problem studied, we must rethink the mathematical model obtained, and so on.

Teachers often restrict the real problems that students face to simple situations so that the resulting mathematical problem is simple and, if possible, provides an analytical solution. Why should we do this today if we have numerical methods, a big computing power and mathematical software available to our students? Examples of complex mathematical problems arise from analysis and design of heat exchangers, chemical reactors, distillation columns, etc, both in steady and transitory regimes. These mathematical problems can be classified in groups: solving algebraic equations, ordinary differential equations or partial differential equations systems.

According to this classification, some teachers of the Chemical Engineering degree at Campus of Alcoy are providing our students with Matlab guide templates to solve these types of mathematical problems, regardless of the subjects in which these problems appear. This action facilitates the student to face real problems by reducing the mathematical difficulties associated.

This paper shows how these Matlab guide templates are and how students use them in different subjects. It allows students to focus on the engineering aspect of the processes, leaving the difficulty of the associated mathematical problem in a second plane. It also makes easy to modify process parameters to quickly see the effect on the main variables of the process (what if? analysis). Consequently, students improve their ability to analyse and interpret the results obtained and their critical thinking skills. And, finally, they know useful computer tools that can be used both academically and professionally.
