This article proposes to incorporate the language of the drawingsto the traditional conventional symbolism used in the study ofelectrical circuits. The objective is to work this representationmode with High School students together with the scientificlanguage. We show that the pictorial mode, that doesn t demandthe knowledge of the official codes, has the potential to detectstudents conceptual difficulties, preventing them from beinghidden by the abstract and anti-intuitive official symbolism. Theidea is to permit that learners, during the learning process,may express themselves through direct and intuitive symbols,instead of being forced to use exclusively the norms and codesfrom official semiotics, as it has been traditionally done. We willsee that the instructional modality based on the students drawingsallows a rich opportunity for the teacher to generate discussionsand to keep up with the construction of his/her student knowledgein classroom.
