Abstract
fatta di metodi e di linguaggi che possono diventare una risorsa importante in ambito educativo in quanto strumenti per rappresentare, comunicare e risolvere problemi. In questo lavoro vengono identifcati alcuni strumenti concettuali dell’informatica la cui utilizzazione in ambito educativo appare particolarmente interessante: rappresentazioni gerarchiche, reti di Petri, grammatiche BNF e schemi entità-relazione. Viene quindi approfondito l’uso di uno di questi strumenti (le reti di Petri) attraverso due semplici esempi nell’ambito della comunicazione e del problem solving. Viene infne delineato un percorso per la ricerca che deve, da una parte, costruire il signifcato di questi linguaggi informatici nella specifcità della pratica educativa, e, dall’altra, renderne agevole l’utilizzazione didattica attraverso lo sviluppo di opportuni ambienti interattivi.
