However, if to compare some families on the basis of objective aspects, such as the social category, come across ourselves with conflicting situations, therefore pertaining children to one same category can present difficulties in the school, while others possess a exitosa trajectory. Studies as of Lahire (1997), Walnut (2004) and Zago (2000) surpass this determinismo of the relation between the social condition and the success or the failure pertaining to school. The disposals are, in agreement Lahire (2001, p 28), ' ' the incorporated product of one socializao' ' consists of a reconstructed reality, which cannot directly be observed, that is, it requires the accomplishment of a interpretativo work. However, it is not possible to deduce a disposal of only one event, therefore the notion of disposal in the ones of a idea of the comment of a series of recurrent behaviors that if repeat. These disposals, in turn, not are permanent, nor generic. Different of the physical or chemical disposals (solubility of the sugar in the water) that they multiply, social disposals can be brought up to date e, in this perspective, it will only be possible to perceive them and to inside understand them of a context on the basis of empirical situations. In this direction, Lahire observes (2001, P. 30): A disposal is not a simple reply and mechanics to a stimulaton, but a way to see, to feel or to act that it is adjusted with flexibility to the different joined situations.
However, nor always the disposal obtains to adjust itself or if to adapt, and the adjustment process is not only the possible one in the life of a disposal. Of this form, it can be inhibited (been of vigil) or be transformed (had the successive congruentes readjustments). Pertaining families to one same social category, with similar objective configurations, present specific strategies in the relation with the pertaining to school context.
