This case study describes a research project conducted with girls aged 11-13 years about their everyday engagement with 'tween' popular culture. The study originated in the context of widespread claims being made in popular culture texts and various institutional reports that girls are being sexualised by 'sexualised' media representations. Identifying the absence of knowledge about girls' use of media and their understandings of 'sexualised' media, the study aimed to investigate the perspectives of girls' themselves. In keeping with the topic, ages, interests and skills of pre-teen girls, the project adopted focus groups and media video diaries as its methods. The case study takes the reader through each stage of the project from its inception to completion. [This content is provided in the format of an e-book.]
