Plagiarism is a consistent source of concern for educators, and particularly so for English for Academic Purposes (EAP) practitioners, whose objective is to equip students for success across the curriculum. Plagiarism has been on the EAP research agenda for some 35 years and remains a topic of considerable research interest. While perceptions of plagiarism have been extensively investigated, a number of questions relating to the prevalence and causes of plagiarism remain unanswered, and solid evidence about effective pedagogical methods is largely lacking. This article outlines directions for future research on the topic and describes specific investigations that could be conducted.
