Abstract: The possibility of using Petri nets as a formal language for pupils to represent their own personal knowledge is examined. The underlying hypothesis is that the process of identifying and defining the knowledge structure of a given content area makes it easier for the pupils to use the knowledge itself. The remarks refer to experiments carried out with pupils in the first years of higher secondary school (14-15 years old) and deal with the graphical representation of problem-solving procedures for some simple mathematical problems.
Keywords: problem solving (using nets); personal knowledge representation; knowledge structure.
