G. B. Demo, G.Marcianó,Contributing to the Development of Linguistic and Logical Abilities through Robotics, EUROLOGO 2007, Bratislava In primary schools robot programming is fun and represents an excellent tool both for introducing to ICT and for helping the development of logical and linguistic abilitiesof schoolchildren. Core of our project is NQCBaby, an Italian version of a Logo-like interface to NQC, so that children used to deal with the Turtle can transfer and adapt their Logo abilities to robots, also discussing the differences. NQCBaby is thougth for RCX but extendible to other small robots. In the meanwhile children are also introduced to NQC, the “real”robot language, by looking at how their descriptions of robot behaviors are translated into NQC “in order to be understood by robots”. NQCBabyis child-oriented rather than robot-oriented like NQC language.---NQCBabyexample // in schools it is Italian-based HiRobby sensor3_light speed(5) repeatalways if_light forward(20) end if_dark left(100) right(random(200)) end end thanks bye Reports and software toolsare downloadableat: //www.di.unito.it/~barbara/MicRobot //i-teach.educ.di.unito.it/course/view.php?id=89Thanks to the students who designed and implemented current version software tools: D.Carbone, D.

In our project with schools, robot programming activities are NOT playful breaks or labs, rather a support for the standard subjects in primary school curricula, i.e. for children from 5-6 years old: cross-disciplinary activities Final goal is to develop activities covering from 5-6 to 15-16 years old pupils different types of robots used for the different ages with the same evolving language mostly Lego RCX and NXT, at prewriting age BeeBot with buttons commands.S m a ll r o b o ts a re s im p le c o m p u te rs t h a t ca n m o v e a u to n o m o u sl y ch il d re n e x p er ie n ce a t an g ib le p ro g ra m m in g a ct iv it y b y m ak in g a ro b o t m o v e U si n g s m a ll r o b o ts i n p ri m a ry s ch o o l g iv es p u p il s co n cr et e y et f u ll p ro g ra m m in g e x p e ri en c es a t th e a g e o f P ia g et ’s co n cr et e o p er a ti o n a l st a g e o f co g n it iv e d ev el o p m en t p ro v id ed t h e la n g u a g e is c h il d re n -o ri en te d
