When you teach mathematics at secondary schools, you enjoy using interactive geometry software with your students. Dr.Geo is one such free software, it comes with some unique features. With such software, students learn geometry the way it should be learned -- by drawing, but Dr. Geo goes one step further.
In this series of articles, I will highlight the advantages of using Squeak/Smalltalk to develop educational software. At some point and based on my experience, I will compare with other development languages. The focus of this article is for educators and developers interested in software programming education applications. In these articles, don't expect to learn about Smalltalk/Squeak programming, my goal is simply to give an overall picture, based on real experience. Feedback is of course very welcome. next article
In this article, I explain how Smalltalk is since 30 years a practical social implementation of the freedom #3 and #4 of the Free Software philosophy: freedom to study, to modify and to redistribute a software.
It has been a long process but it looks like it is done now, at least regarding the Squeak version distributed for the OLPC XO laptop.
J'ai développé en 2005/2006 une version Squeak/Smalltlak de Dr. Geo. Il y a peu, José Luis Redrejo un smalltalker espagnol d'Extremadura m'a proposé quelques modifications pour internationaliser cette version de Dr. Geo et l'intégrer dans le Squeak espagnol distribué avec leur distribution GNULinex. J'en ai profité pour tester cette nouvelle version dans le portable à 100$ et produire quelques vidéos sur son utilisation.
