Instrumental orchestrations by a university teacher in an online linear algebra course
Résumé
In this article, we present an instrumental orchestration for online math education. The case study is of a university teacher in a linear algebra course with engineering students in a remote learning setting. We used the instrumental orchestration approach as a theoretical framework for planning and organizing the artifacts involved in the environment (didactic configuration) and the modalities of their implementation (mode of exploitation). The activities were designed using virtual manipulators, guided exploration sheets, and video recordings of individual or paired work by the students. The results of the observation of five sessions are presented and the orchestrations of a pedagogical sequence to introduce the concepts of value and eigenvector are briefly discussed. This work suggests new instrumental orchestrations for the teaching of mathematics online.
