The main objective of the research was to investigate the student s motivation for the study in association with sociodemographic, school, computer and cultural practices skills s variables. This study represents an excerpt of a larger research entitled Youth and Media: school and social contexts, which sample was 3705 9th grade students of thirty-nine public schools in Rio de Janeiro, divided into five demographic strata: nearby and far slums large schools, nearby and far slums small schools, small and reference schools. From models, and the multiple linear regression, we identified significant variables for motivational composition: computer educational use, cultivated cultural, leisure and sport practices in their free time, religious and watching television practice and the results indicated the stratum small school nearby slum as highly motivated. From this new base it was possible to identify the advanced scholastic condition (students with no history of repetition), the social use of computer, Internet cafes (Lan houses) computer use, and religious practice as variables associated to a favorable outcome. However, on this stratum, it is clear that the level of unfavorable outcome is also high (88.1 percent). This relationship made us infer that factors within schools that belong to this stratum act to contribute to the maintenance of inequality despite the high motivation of its students. The arguments of the effect-territory helped us understand this process, highlighting the existing complexity in such schools.
