Mathematics laboratories for teaching, a productive metaphor
Keywords:
mathematics laboratories for teaching, teachers collective work, tools for doing, teaching and learning mathematicsAbstract
The metaphor of "laboratories" to do and learn mathematics appeared in history, when emerges the necessity of renewing and developing mathematics teaching. The conference will show the evolution of this metaphor, since the creation of ICME (1908). The mathematical laboratories are always presented in relation to the instrumentsthey contain, so the evolution of the metaphor accompanies the evolution of these instruments. We show in this paper how the evolution of technological environments makes it possible to conceive, in the space of the ‘ordinary' mathematics class, moments of life of a laboratory of mathematics, and then to prolong, at a distance, these laboratories. It is also shown that the development of mathematics laboratories for students implies the development of mathematical laboratories for teachers. This viewpoint will be supported by the French experience of a teacher association developing online resources, Sésamath. We deduce the need for new theoretical approaches articulating resource design, evolution of practices, and professional development, combining individual and collective aspects of teachers work.References
