ARI-LAB 2 is an open multi-environment system for developing skills in solution to arithmetical problems for children of the primary and the lower secondary school. The project of ARI-LAB is based, on the one hand, on research on hypermedia and communication systems and on the design and implementation of visual microworlds; on the other hand it takes into account the research in mathematics education with particular reference to the studies in applied problem solving, on the role of visual representations in learning processes and on interactive learning. In ARI-LAB problem solving is carried out by exploiting the action, representation and communication possibilities made available by the different tools which have been integrated in the system. ARI-LAB 2 addresses two kinds of users: the teacher and the pupil. By interacting with ARI-LAB 2, the pupil can build his own solution to some arithmetical problems, by interacting with a structured and interconnected set of environments of different kind. These environment include: 10 microworlds for solving arithmetic problems; an environment for building and describing problem solutions; a communication environment through which a student can interact with his own mates and/or with his/her teacher by sending messages and solutions; a database of solved problems. Apart from the previous environments, the teacher has also at his/her disposal an environment for planning and customizing the educational activity with his/her students: writing problem texts, constructing problem solutions, examining and commenting the students' work, configuring the system for every student of his/her class. In ARI-LAB 2 it is integrated a vocal synthesizer for developing and validating the basic mathematical skills (such as the counting, the coordination between the oral and written representation and that in digits of a number, the numerical equivalence, etc). There are also some movies in Italian for deaf-and-dumb to adapt the system to the specific demands of the deaf children. The interface of ARI-LAB 2 is currently available in three languages of the European Community: Italian, English, and Spanish. Ari-Lab 2 has been developed through the European project named ITALES - Innovative Teaching and Learning Environments for Schools (IST-2000-26356), within the Fiveth Project, key action "School of Tomorrow").
ARI-LAB 2 è un sistema aperto multi ambiente per lo sviluppo di capacità di soluzione di problemi aritmetici in bambini della scuola primaria e secondaria inferiore. Il progetto di ARI-LAB 2 si basa, da un lato, sulla ricerca relativa ai sistemi ipermediali e di comunicazione e sulla progettazione e implementazione di micromondi di natura visuale; dall'altro lato il progetto prende in considerazione la ricerca in didattica della matematica con particolare riferimento agli studi relativi al problem solving, al ruolo delle rappresentazioni visive nei processi di apprendimento e apprendimento. In ARI-LAB 2 l'attività di problem solving viene effettuata sfruttando le possibilità di azione, di rappresentazione e di comunicazione messi a disposizione dai diversi strumenti che sono stati integrati nel sistema. ARI-LAB 2 prevede due tipi di utente: l'insegnante e l'alunno. L'alunno, interagendo con ARI-LAB 2, può costruire la propria soluzione, per un dato problema aritmetico, interagendo con un insieme strutturato e interconnesso di ambienti di natura diversa. Tali ambienti comprendono: 10 micromondi per risolvere problemi aritmetici; un ambiente per costruire e descrivere le soluzioni dei problemi; un ambiente di comunicazione attraverso il quale lo studente può interagire con i propri compagni e/o con l'insegnante inviando messaggi e soluzioni; un data-base di problemi risolti. L'insegnate ha a disposizione, oltre agli ambienti precedenti, anche un ambiente che gli consente di pianificare e personalizzare l'attività didattica con i suoi allievi: scrivere e impartire testi di problemi, costruire soluzioni, visionare e commentare il lavoro degli studenti, configurare il sistema per ogni studente e/o ogni sua classe. In ARI-LAB 2 è integrato un sintetizzatore vocale per lo sviluppo e la validazione di abilità matematiche di base (quali, ad esempio, la conta, il coordinamento fra rappresentazione orale, scritta e in cifre di un numero, l'equivalenza numerica, ecc.) e di filmati in LIS (Lingua Italiana dei Segni) per adattare il sistema alle specifiche esigenze dei bambini sordi. L'interfaccia di ARI-LAB 2 è attualmente disponibile in tre lingue comunitarie: l'italiano, l'inglese, lo spagnolo. Ari-Lab 2 è stato sviluppato e sperimentato nel corso del progetto europeo ITALES - Innovative Teaching and Learning Environments for Schools (IST-2000-26356), nell'ambito del Quinto Programma Quadro, azione chiave "School of Tomorrow").

Abstract
ARI-LAB 2 is an open multi-environment system for developing skills in solution to arithmetical problems for children of the primary and the lower secondary school. The project of ARI-LAB is based, on the one hand, on research on hypermedia and communication systems and on the design and implementation of visual microworlds; on the other hand it takes into account the research in mathematics education with particular reference to the studies in applied problem solving, on the role of visual representations in learning processes and on interactive learning. In ARI-LAB problem solving is carried out by exploiting the action, representation and communication possibilities made available by the different tools which have been integrated in the system. ARI-LAB 2 addresses two kinds of users: the teacher and the pupil. By interacting with ARI-LAB 2, the pupil can build his own solution to some arithmetical problems, by interacting with a structured and interconnected set of environments of different kind. These environment include: 10 microworlds for solving arithmetic problems; an environment for building and describing problem solutions; a communication environment through which a student can interact with his own mates and/or with his/her teacher by sending messages and solutions; a database of solved problems.
