A calculadora científica na transição de artefato a instrumento: uma abordagem instrumental nos cursos de engenharia

Abstract

The present study investigated the use of the scientific calculator in the transition from artifact to instrument in the study processes around the Differential Calculus of the first semester of Civil / Electrical / Mechanical Engineering courses at a private university in the city of Belém-Pará. The activity analyzed was designed to provide the use of the Casio fx-82MS scientific calculator. The research took the form of a case study. To achieve this objective, a workshop was first proposed to evaluate the students' experience in using the calculator and, a posteriori, to apply activities involving Differential Calculus and from the point of view of Instrumental Genesis in order to establish its role In a process of construction of knowledge, so the results were analyzed to the Situation (s) of Instrumented Activity (s) - SAI, in order to analyze actions of instrumentation. Based on the activities, we observed that the majority of undergraduates did not know the scientific calculator and its resources until the realization of the workshop, getting to know it during the activities as they appropriated their resources to carry out the activities of notions of Calculation Differential, potentiating it from artifact to instrument.
