In the training of future informatics teachers the students obtain experience with different methods of programming. As well, the students become familiar with programming by using the robotic system Lego Mindstorms. However, the small number of Lego systems available is a limiting factor for the teaching process. Use of virtual robotic environments seems to be a suitable alternative for dealing with an insufficient quantity of hardware tools. The resulting programs are created and tested in the virtual laboratory and can be subsequently implemented into a real robot model. In such cases, teaching no longer depends on the available number of hardware kits and the form of teaching can be changed from group to individual. This paper describes our experiences with students' learning with the robotic system Lego Mindstorms, programming environments Bricx and virtual educational environment ROBOTC. One approach to making teaching programming language attractive is the use of robotic kits and virtual environments in the classroom.
