Situated in the South Korean context that there is an increasing social concern on 6th graders and the denigration of their value system, this qualitative study sought to understand the culture of 6th graders by collecting and analyzing data from a series of participatory observations and in-depth interview. Throughout the data collection and analysis, this study paid a special attention to formative factors such as socioeconomic status and school district that might have impact on individual students’ school lives and their belief systems. Major findings are as follows. First of all, the life of 6th graders was closely engaged with the Youtube; and they used the Youtube as a great tool for entertainment. Second, in spite of an increasing emphasis on cooperative learning, the students’ ways of participating in group activities were closer to a division of labor than a genuine cooperation. Third, their self-identification was based on their perceived pressure of academic achievement or anxiety about their relationship with peers. Surrounded by these circumstances, the students perceived the times that they spend in the schools and classrooms as those for relaxation or play. Finally, this study revealed that the students’ school lives and value systems are quite dependent upon their parents’ socioeconomic status and school district. The discussion highlights what should older generations and school mean to our students.
