A proposal of instrumental orchestration to introduce eigenvalues and eigenvectors in a first course of linear algebra for engineering students

Abstract : We present an advance of our doctoral research on the complex process of instrumentation that students develop when using various artifacts in a teaching situation to introduce the concepts of eigenvalues and eigenvectors in a traditional course of linear algebra in engineering. The activity to be proposed involves a lot of numerical calculation, so the need to configure the different instruments is evident, to propose a certain instrumental orchestration. The objective of this work is to integrate digital artifacts in the teaching of mathematics, for once transformed into cognitive instruments, an orchestration can be configured. As part of the pilot phase of the study we observed two students. We present results of this case study that allowed to identify from interviews and classroom observations of the use of resources.
