This KTurtle is the KDE app with the same name so it inherits of all its features.
KTurtle aims to make programming as easy and touchable as possible, and therefore can be used to teach kids the basics of math, geometry and... programming.
The programming language used in KTurtle is loosely based on Logo. KTurtle allows, just like some implementations of Logo, to translate the programming language (the commands, the documentation and the error messages) to the native language of the programmer. Translating the programming language to the native language of the programmer is one of the many ways KTurtle tries to make learning to programming more simple. Other features to help to achieve this goal are: intuitive syntax highlighting, simple error messages, integrated canvas to make drawings on, integrated help function, slow-motion or step execution, and more.
