Welcome to Dr. Geo!

Dr. Geo is a winning award interactive geometry software for Linux, XO laptop, Windows and Mac OS X. Written entirely in Pharo Smalltalk, Dr. Geo allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is usable in teaching situation with students from primary or secondary level. It is simple and effective with some unique features as Smalltalk scripting and programming.

This video clip demonstrates some Dr. Geo II features. For a more static presentation, the reader can look at this gentle overview prepared for the ESUG2008 Technological Innovation Awards. For fresher news, one can read my blog articles related to Dr. Geo.

I started writing Dr. Geo in 1996 with the idea of empowering the user. As of today Dr. Geo comes with several user power tools:

• A user friendly interface suitable to 10 years old kids
• A script system to extend DrGeo capabilities
• Smalltalk programmed interactive sketch
• An interactive geometry framework entirely written with the dynamic and interactive Smalltalk language. It gives power to the user to modify Dr. Geo while it is running.

My goal is to provide an interactive geometry framework for primary and secondary education in mathematic and physic sciences. The main use of Dr. Geo is the construction of geometric sketches to explore properties. It can be used by a teacher to set up a teaching situation on a specific topic.

Thanks to its unique programming features, the user is entirely free to design more complex contents: for example with script, one can build a geometric sketch to compute the slope at an arbitrary location of a given curve. Or the user can describe a fractal curve with Smalltalk programmed sketch. The integration of user programming tools in Dr. Geo opens large use cases.
