Students have “no understanding” of what plagiarism is and why they must avoid it, according to new research. An education research fellow at the University of Otago, finds that universities might need to consider their plagiarism policies and how they might “influence or confuse students in counterproductive ways”. The qualitative study, published in the journal Higher Education, found that although “aware of plagiarism as a concept” and believing that those who “intentionally cheat are cheating everybody”, students were ignorant of the potential implications of unintentional plagiarism.

Police and education authorities are investigating allegations of mass cheating by international students at tertiary institutes throughout the country. The man who reported the issues alleged that he was contracted to write assignments for students at various universities who could not meet language standards.

More than 600 University of Otago students were disciplined last year for criminal or disorderly behaviour and dishonesty. Their offending included electronically altering exam results, falsifying documents, plagiarism, stealing other students' work or possessions, setting couches on fire, assault, trespass, wilful damage and offensive behaviour.

Cheating is up more than 20 per cent at the country's biggest university. It have been identified 201 cases last year, compared to 166 in 2007, although the student roll remained steady at 38,550. Using cell phones, sneaking unauthorized notes and material, with unpermitted calculators, dictionaries and electronic devices and writing answers before exams started are some of the new and old methods for cheating.
