Algebraic Expressions and Robot Programs in Junior High Schools
نویسنده
چکیده
In our ICT activities in junior high schools pupils program the RCX and NXT Lego bricks using a Logo-like language supplemented by a program development environment specifically implemented for young students. In their first programs, pupils mainly aim at moving their autonomous robots. We describe how teachers and pupils have analyzed with us a number of robot programs, performing a static analysis of the code, for specifying the length of the path a robot covers when a program is executed. When sensors are used this length is specified as an expression containing variables. The analysis associating algebraic expressions to robot programs can be used as a teachers support in motivating elementary algebra, a typical subject addressed in junior high schools. In this activity robotics is used as means to concretely manipulate topics of traditional disciplines. It is integrated in standard school curricula and becomes an active learning environment.
