practices within a classroom and what the teacher says on them, between <strong>le</strong>arning and its<br />
social usefulness.<br />
Discipline awareness as it comes up in what students say is not, therefore, the sum of the<br />
different perceived characteristics, but rather the delicate elaboration of links between these<br />
different characteristics. To make it possib<strong>le</strong> to describe know<strong>le</strong>dge networks is one of the<br />
interesting aspects of S.I.A. since this possibility is directly linked to one of the prob<strong>le</strong>matic<br />
in didactics, the study of students and teachers representations and conceptions.<br />
2.3. Ru<strong>le</strong>s interpreted as tracks of skills.<br />
One of the last S.I.A. fields of applications in Mathematics didactics that we will present<br />
is that of skills reconstruction stemming from observation of student behaviours. As done<br />
before, ru<strong>le</strong>s of the type “if A then B” showed by S.I.A. must be interpreted.<br />
A and B still refer to observab<strong>le</strong> behaviours. The implicative relationship can be interpreted,<br />
according to the different cases, such as : B is a consequence of A or A is an explicative<br />
factor of B. The reconstruction of students’ skills to be ab<strong>le</strong> to comp<strong>le</strong>te a particular task can<br />
be read in the implicit ru<strong>le</strong>s which govern over students behaviours.<br />
The examp<strong>le</strong> that we have chosen to explore stems from a study registered in the didactics<br />
of mathematics, even though it is only a part of a much wider research which involves<br />
different didactical disciplines.<br />
The main prob<strong>le</strong>matic in which this study makes sense is in the relationships of teaching and<br />
<strong>le</strong>arning, or to be more precise, that of measuring the effects of a particular pedagogical set of<br />
devices on some mathematics <strong>le</strong>arning. Numerous prior studies can be quoted on this theme,<br />
amongst which two equally interesting syntheses have been recently and simultaneously<br />
published (on one hand Mercier and Buty and on the other hand Bru, Altet, Blanchard-<br />
Lavil<strong>le</strong>). They prove <strong>le</strong>gitimate the hypothesis according to which the particularities of didactic<br />
management of teaching and <strong>le</strong>arning situation by the teacher can influence the building of<br />
mathematical know<strong>le</strong>dge and the appropriation of other know<strong>le</strong>dge of the discipline by the<br />
concerned students. We will extend this hypothesis to attitudes and behaviours when faced<br />
to specific tasks.<br />
The study tries to measure the effects of a pedagogical set of devices, which make it necessary<br />
to compare skills developed by students within the set up and the skills of students who are<br />
not in it. We will get back to our goal later. However, one of stages of this undertaking, is<br />
first to describe the skills brought forth by the group of students whi<strong>le</strong> they were doing the<br />
specific subjects tasks.<br />
The examp<strong>le</strong> we will bring out here is, as we have mentioned above, is in this perspective of<br />
research . It is backed up by the analysis of skills in geometry and language skills of 9 and<br />
10 years old pupils who had to do a writing geometry task.<br />
The task is the following : “how to draw this figure ?”<br />
