In Common Culture the British social scientist Paul Willis described young people's ICT use as a cultural practice. I wonder if a study on ICT use could not be rooted in cultural sociology. So have a look at Willis, if you want to proceed in that direction I would explore the Journal Cultural sociology and the handbook by Hall, Grindstaff & Lo (2010). Next step ask yourself about methods and focus, how to open windows on the cultural practice of ICT use and what  are essential issues, what is at stake. Good luck!

Refer to some of our work, were we did ICT studies both in schools and universities
