Presentation Abstract

The last decades brought about new challenges for teachers: we talk about educating, not only instructing; educational goals contemplate contents but also abilities, attitudes and values; compulsory schooling was increased, students are heterogeneous and literacy is considered to be a desirable competency for All.
These changes imply the need to modify classroom practices. Collaborative work revealed a potential that was stressed by several authors (Cobb, 1994; Schubauer-Leoni and Perret-Clermont, 1997; van der Linden et al., in press) for it allows pupils to work in the proximal zone of development, to create socio-cognitive conflicts, establish innovative didactic contracts and develop mathematical and communicational competencies. Therefore, the combination of the theories of Piaget and Vygotsky has been defended as a useful conceptual tool for understanding knowledge construction (Tryphon and Vonwche, 1996).

This study is part of a broader project called Interaction and Knowledge whose main goal is to study and implement peer interactions in the Mathematics classes as a way of promoting pupils' academic self-esteem, socio-cognitive development and school achievement. The project Interaction and Knowledge is divided into two levels: 1) - A micro-analysis level, in which we studied different types of peers, their interactions, the tasks, the mistakes pupils make and the progress that peer interactions are able to generate in statistical contents and logical development; 2) - An action research level, in which some Mathematics teachers implemented peer interactions as a daily practice during at least a school year. The data we are going to present are from level 1, related to the content of Statistics.

The sample had 533 subjects (25 classes) and it was gathered in two consecutive school years. All subjects were attending the 7th grade. The subjects were divided into an experimental group and a control group and the ones from the experimental group worked in peers (136 dyads) during three sessions, solving challenging problems. After that each class participated in a general discussion that was videotaped and in which pupils discussed some of the tasks they had solved in peers.

Detailed analysis of some episodes illustrates the role of the interactive processes at stake. Knowing how social regulations take place, how solving strategies are chosen, who leads, how and when this leadership is performed, how stalling moments are overcome or mistakes are found, or when socio-cognitive conflicts arise are all essential elements to understand the complexity of any interactive process and the contributions it may make to the appropriation of knowledge and the mobilization of competencies. At the same time, this analysis allows us to understand how an inter-subjectivity is constructed and the role it plays in attributing meaning to statistical tasks.

The facilitating character of collaborative work is undeniable in the studies we have undertaken (Carvalho and Cesar, 2000; Carvalho and Cesar, in press; Cesar, 1998, 2000a, 2000b, 2000c). However, it is essential to identify and explain the mechanisms that generate subjects' progress and explore the contributions of collaborative work to statistical literacy and to the education of critical and participant citizens.
