Plagiarism is a pervasive challenge throughout academia perpetuated by the advent of technology, lack of ethical education, and the ambiguity in its definition. Plagiarism in the United States’ higher education settings has gained more attention over the years as international student population has increased. Considering how higher education institutions are growing as international spaces due to globalization, it is crucial to closely examine ethical issues concerning the diverse and multicultural student population. A prevailing view of plagiarism asserts that international students’ (...) plagiarized texts are influenced by their ethical judgment and cultural backgrounds. This invites the question of whether ethical decision-making processes and cross-cultural perspectives are taken into consideration when instructors encounter instances of plagiarism committed by international or multicultural students. This paper intends to expand on the concept of culture in regard to the ethical dilemmas of plagiarism. Extending the discussions of cross-cultural influences surrounding plagiarism and ethical judgments in higher education, we position ourselves as viewing culture through the expanded lenses of macro- and micro-level cultural practices. In response to the internationalization of higher education, we advocate for changes in higher education curricula and instruction towards more cultural responsiveness and inclusivity. Instead of questioning or criminalizing ethics based on cultural background, especially in the cases of plagiarism committed by international students, we suggest approaching culture using the expanded perspectives of macro- and micro-cultural practices. The paper also provides recommendations for higher education instructors when tackling ethical dilemmas while preventing and managing situations of plagiarism. (shrink)
