Towards relational thinking by Matlab LiveScript in linear algebra

This paper is focused on the use of Matlab LiveScript in linear algebra courses for freshmen, aimed at fostering a transition from an instrumental approach to a more relational one when students solve a mathematical task. To analyse students' explanatory writing of a mathematical solution text we choose a model which looks at the ATD frame, with the addition of a logical chain component, from the point of view of Grice’s maxims. The preliminary results show a transition from an instrumental approach to a relational approach, emerged from improved verbal arguments that make evident the relationships among the various mathematical objects.
