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
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 :
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.
