Plagiarism is commonly known as the practice of taking an individual's work and passing it on as one's own. This is a barrier that higher education institutions have consistently faced over the past decade (Neville, 2010). In order to deal with the problem of plagiarism, we need to address the reasons. This essay will shed light on the different causes of intentional and unintentional plagiarism. The focus is on three main ideas: It begins by stating the most common reasons for intentional plagiarism, namely poor student time management and the importance of achieving high grades. Next, the causes of involuntary plagiarism are discussed, which consist of the development of a psychological phenomenon that can lead students to plagiarize unconsciously, then the focus will be on the incomprehension experienced by students due to the lack of clarity of the definition of plagiarism. Finally, the effect of cultural differences on international students' plagiarism is examined. First, the most common cause of intentional plagiarism among students at English-speaking universities is the various forms of pressure that students face, such as time pressure. This claim is supported by research by Neville (2010) which demonstrates that 54% of plagiarism among students is caused by poor time management skills. University students are bombarded with a heavy workload and the majority say it is difficult to fit classes, tests and due dates (Sterngold, 2004 cited in Neville, 2010) . This is confirmed by the typical responses of students at American universities: “So much homework in 12 weeks.” and the plagiarism was justified by the students... middle of article... the social and academic aspects of their lives. The implementation of this system could lead to a reduction in student plagiarism in universities. Works Cited Bamford, J. and Sergiou, K. (2005). Inquiries into university teaching and learning.
