To do this, a think-aloud method and a semantic network analysis were used. The conclusions are as follows. First, concepts that are of interest continue to be used in the scientific inquiry stage. Most of these concepts are related to experimental instruments. Second, the concepts of high frequency are representative of the concept network of each process skills.
