plagiarism theorists, such as Susan Blum, consider how contemporary cultural practices of sampling and borrowing are challenging our traditional definitions of plagiarism—and how they are confusing to students who must abandon their normal habits of Facebook sharing or re-Tweeting in order to conform to the complex rules of scholarly citation. This may have some bearing on the case of cheating in MOOCs, especially when the students hail from different countries, where the rules of academic citation might differ from those in the home country of the faculty member.
