Experiments with Aplusix in Four Countries

The Aplusix system has been designed for helping students to learn algebra. Its capacity to tell the students whether their calculations are correct or not, to provide families of exercises of a chosen level, and to give scores after tests allows this system to be used in the regular functioning of the class. Its capacity to record the students' actions and to replay the students' work is a valuable feature for the researcher in mathematics education. In this paper, we describe four experiments conducted in four different countries with different goals: remediation piloted by researchers in Italy; remediation integrated in the regular functioning of classes in Brazil, collaborative learning in India, and learning and use during the entire school year in France.
