"Students who are fully aware that their actions constitute plagiarism - for example copying published information into a paper without source attribution for the purpose of claiming the information as their own, or turning in material written by another student are guity of academic misconduct...
Students are not guilty of plagiarism when they try in good faith to acknowledge others' work but fail to do so accurately or fully. These failures are largely the result of failures in the prior teaching and learning: students lack the knowledge of and ability to use the conventions of authorial attribution."
