摘要：For some years academics have debated the role in higher education of Facebook, the world's most extensive social networking site. At first there was enthusiasm—it was a new tool that could be 'repurposed' foreducation; then, as Facebook became more widespread, its use seemed less than opportune. But now, with so many students already engaged before they even come to a university, perhaps it is impossible to avoid the conclusion that Facebook is as natural to education as the commute, the computer, and everything else which students 'bring'. This paper first presents a summary of what Facebook affords, by way of its design and use, for online communication and networking, demonstrating the central role of reciprocal acts of attention exchange in this system. It then analyses, through a critical reading of research into Facebook and education, the way Facebook challenges traditional understandings of university education and the relationships between teachers andstudents. It concludes that, however we might seek to use Facebook in higher education (and there are many reasons we might), itsuse will always be shaped by—andindeed give rise to—a blurring of the traditional boundaries between formal and informal education
