O desenho como mediador representacional entre o experimento e esquema de circuitos elétricos

this article presents results of an investigation structured from multimodal representational principles in which drawing is used as mediatory activity to solve conceptual problems of high school students' learning when they pass in the experimental way for the conventional schemes used in electric circuits. the modal representation based on drawing allowed to open an initial space of dialogue for establishment of meanings linked to the content of electric circuits and it was later formalized with the official schematic language. in compatibility with the multimodal referential founds indicate that the mediation through drawing transforms it in a kind of representational bridges that facilitates the learning of the schemes and scientific contents in the study of electric circuits.
