Cabri-geometry is the result of researches within the Joseph Fourier University of Grenoble and the CNRS, undertaken by the Laboratoire de Structures Discrètes et de Didactique (1984-1995), followed up by the team EIAH(Environnements Informatiques d'Apprentissage Humain) in the laboratory LEIBNIZ (1995-2002), and the team DIAM (Informatique et Apprentissage des Mathématiques) until 2011.

Now Cabri software is developped and distributed by the Cabrilog company.

Cabri history (1985-2007)

In 1985, Jean-Marie Laborde, computer scientist, mathematician and researcher in discrete mathematics, proposes the creation of a rough book for geometry, "Cabri-géomètre", allowing an exploration about properties of geometry objects and their relationships. At the sides of Jean-Marie Laborde, the craftsmen of the realization of the software are Philippe Cayet, Yves Baulac and Franck Bellemain as students preparing doctoral thesis.
First efforts lead to acknowledged work:

  • In 1988, a first version of Cabri-géomètre is noticed by Apple and is awarded Education Trophy of the year.
  • In 1989, Cabri-géomètre is available on the French educative market with the support of the Ministry of Education, then in many countries as MacOS or DOS version. .

This double reference underlines the pluridisciplinarity of the team that Jean-Marie Laborde will unite from 1990 within a great project in the Computer Science and Applied Mathematics Institute in Grenoble (IMAG), by gathering searchers in computer science, didactics of mathematics, mathematics, artificial intelligence and psychology, as well as teachers.
Works take place inside the laboratory "Structures Discrètes et Didactique", but also in schools around Grenoble, especially inside the College of Moirans, where Bernard Capponi sets up a real observatory of usages of Cabri-géomètre. Today directions of research leaning on Cabri-géomètre have largely diversified, on the didactic side through impulsion given by Colette Laborde, as well on the artificial intelligence side under Laurent Trilling's management, responsible for the PLIAGE team (Programmation Logique, Intelligence Artificielle et Génie Éducatif), as well on the distance learning technologies side in the framework of the project Télécabri leaded by Nicolas Balacheff.
During the nineties, the first generation of Cabri-géomètre has yielded the place to a new generation "Cabri II" thanks to developments made by Jean-Marie Laborde, Franck Bellemain and Sylvie Tessier as well as the industrial support of Texas Instruments.
The alliance between Cabri-géomètre project and Texas Instruments is at the source of a real revolution in conditions of teaching mathematics with the availability of a calculator within student's bags including various calculation environments and dynamic geometry : the TI-92.
In the beginning of 2000, Jean-Marie Laborde creates the company Cabrilog, for the edition and development of Cabri software in order to produce new versions for computers and calculators.
In early 2003, a new version is available : Cabri Geometry II Plus, followed by a new geometry software: Cabri Junior for TI83 and TI84 calculators.
In September 2004, at Cabriworld in Roma, Jean-Marie Laborde presents the release of Cabri Geometry II plus for MacOS X and, at the same time, a completely new product, Cabri3D,an interactive solid geometry software.

Development of Cabri Geometry II Plus continue with the version 1.4 (september 2007) including many new features and facilities for the teachers.
