Cabri software allow students to approach dynamic geometry in an intuitive manner. To me, Cabri remains a model and a source of inspiration with respect to the way in which it implements a concept using direct manipulation: (…)it allows one to really “manipulate” and “see” geometry.

I believe that the main benefit is that Cabri allows students to draw their own conclusions. The future of teaching mathematics begins with the visualization of mathematical problems and Cabri plays a part in this education of the future.

Cabri is at the center of my research activities. It is a mine of questions for educational instruction. I currently use it to involve students in work that is more than just copying down demonstrations.

**Sophie Soury-Lavergne

What pushed me to immediately use Cabri was the facility with which I could create geometric constructions, discover properties and draw conclusions about constructions, visualize geometric connections, reconstruct a figure step-by-step, etc.

**Mathematics and Physics Professor

It is dynamic geometry software with a very intuitive user interface. Figures that are created are of high quality. I also use other software programs, but none of them allows me to create such complex figures in just a few minutes. The advantage of Cabri is its simplicity.

What surprises me the most in using Cabri II Plus is that one is able to forget that he is using educational software and can just concentrate on the geometric problem at hand; the software becomes an easy tool to use at any time.

This software is easy to manipulate unlike other software that force, for example, constructing points to create an angle… In addition, it is a way to show students the various properties of transformations.

I consider Cabri’s dynamic software as more of a support in students’ learning when they are accompanied by activities.

**Gonzalo Zubieta Badillo
Mathematics Professor

In class, I have used CABRI as a dynamic data generator, to explore such problems as view angles in theatres, the maximum angle for a shot on goal (hockey) and the minimum path lengths. Applets for showing equivalences in geometrical relationships for trigonometry and pythagoras’ theorem or locus of a point have been important. As a school we have appreciated the recent upgrades.

I have discovered Cabri a long time ago during a presentation. It was the first time I heard about software of dynamic geometry and I saw all the possibilities that could be "opened" for the teaching of Geometry. I'm a teacher but for the last 7 or 8 years I have been a teacher trainer. I use Cabri with teachers, but also I use Cabri for my personal work, for preparing conferences, documents, etc. I work with Cabri and I just like the way we work with it, I feel very "comfortable" with Cabri.

Using software with students allows an approach to geometry complementary to the traditional “paper-pencil” method thanks to the dynamic element.

**Sylvia Coutat

After having worked with Cabri, I am always disappointed by using other dynamic geometry software especially from the instructional point of view: Cabri is by far the easiest to teach and it is also the software that makes students forget they’re even doing mathematics.

Students catch on surprisingly quickly to the software’s toolbar and in one hour they are all able to use it correctly. Several of them had already used it in middle school.

**Christine Dequier
Mathematics Professor
France**

By using Cabri, you cannot go wrong. Students can develop their mathematical reasoning and logic and may even discover things that the teacher hadn’t thought about.

**Lil Engström
Associate Professor
Sweden**

It is an answer to problems of teaching, especially those concerning the activity of students in the development of certain concepts. The only other software with which I have worked has a structure that seems more rigid and does not allow room for “exploration.”

**Jean-Pierre Massola
Professor of Mathematics and Education at IUFM
France**

I have integrated using Cabri with much success as an essential element in my program with respect to the development of self confidence and the understanding of mathematics.

Dr. Stephen Arnold

Australia

This is a software that is dynamic, simple to use, precise, and reliable.

**John Pill Christensen
Middle School Mathematics Teacher
Denmark**

The major benefit I experience by using Cabri is being able to activate the students and getting a direct tool for explaining what to do in a specific geometrical situation. Cabri is a software easy to use.

**Mathematics Teacher
Sweden**

It took me an hour or two to get acquainted with Cabri II Plus. Cabri has good possibilities to show and prove many different rules of geometric figures.
