CSCL in Math Education

New frontiers in math education require new way of thinking learning. Nowadays, almost everywhere, educators are dealing with mathematics curriculum reform in order to make mathematics more relevant and meaningful for students. In particular they aim to encourage students to think critically, and make the process of learning mathematics more student centred and interactive. This work illustrates a study of metacognitive processes, set up in problem solving conditions and applied to the math field, supported by a Computer Supported Cooperative Learning environment, Math&Co.. By stimulating their mental processes, Math&Co. should enable students to develop higher level math skills and acquire problem solving abilities. In this sense, it aims to contribute to the cultural development of citizens, in order to enable them to participate in the social life with awareness and critical eye
