After an introduction which addresses some basic questions, this article is organized around three points: (1) The theoretical framework of the so-called “Instrumental approach” which has been a theme in the last two CAME symposia; (2) A consideration of two processes (instrumentalization and instrumentation) which interact in the instrumental genesis; and (3) The introduction of the idea of instrumental orchestration.Expand

Transforming any tool into a mathematical instrument for students involves a complex ‘instrumentation process and does not necessarily lead to better mathematical understanding.Expand

We study in this article mathematics teachers’ documentation work: looking for resources, selecting/designing mathematical tasks, planning their succession, managing available artifacts, etc. We… Expand

A rapid technological evolution (Chapter 1), linked to profound changes within the professional field of mathematics (Chapter 3), brings into question the place of techniques in mathematics teaching (Chapter 5).Expand

The large-scale distribution of PCs and handheld devices made software for use in mathematics education available to both students and teachers. Currently, programming languages, graphing software,… Expand

This chapter will highlight the interest and necessity of considering a plurality of perspectives (or dimensions) when addressing the issue of the integration of information and communication technologies (JCT) into the teaching and learning of mathematics.Expand

In this article, we study didactic phenomena identified in integration experiments within our classes, CAS (implemented in calculators). From this study, we show the interest of an instrumental… Expand
