Multidimensional perspective about resistors association in electric circuits: part II - theoretical-experimental issues, registers and technological domains

Perspectiva multidimensional sobre a associação de resistores em circuitos elétricos: parte II - questões teórico-experimentais, registros e domínios tecnológicos

Abstract

This is the second of two closely related papers describing the multidimensional perspective about resistors association in electric circuit analysis. In the first paper we discuss nonscientific conceptions, focusing a theoretical framework and instructional materials, language, diagrams and other issues. Here, theoretical and empirical problems are exposed. A general framework based on registers of representation and technological domains is presented. Previously, materials and teachers can explore exemples belonging to a restricted set, which commonly is treated as a conventional symbolic representation. Thus, has been verified a prevalent morphological reasoning in several learning situations. Physical aspects, vocabulary, diagrammatic and experimental contents are brought up, exposing the need for their integration if an effective learning is desired. Registers of semiotic representation and non-semiotic elements (empirical set) are recommended to facilitate the students’ conceptual perceptions, their capable of mobilizing the plurality of diagrams and connections, also allowing teachers a better conceptual framework.
