Acting with academic integrity means, in brief, not submitting the statements, work, or ideas of others as one’s own. Consult with the instructor or lab staff before completing assignments if you have concerns about the correct way to reference the work of others or if you are in doubt about what constitutes academic dishonesty. More generally, please familiarize yourself with the University’s policy on academic honesty and the relevant sections of the Student Handbook.
Failure to maintain academic integrity on an assignment will result in a penalty befitting the violation, up to and including failing the course and further University sanctions. In the event that any concerns do arise regarding this matter, we will forward all related materials to the College Dean of Students for further review and action.
From the Student Manual of University Policies and Regulations:
As students and faculty of the University of Chicago, we belong to an academic community with high scholarly standards of which we are justly proud. Our community also holds certain fundamental ethical principles to which we are deeply committed. We believe it is contrary to justice, to academic integrity, and to the spirit of intellectual inquiry to submit the statements or ideas of work of others as one's own. To do so is plagiarism or cheating, offenses punishable under the University's disciplinary system. Because these offenses undercut the distinctive moral and intellectual character of the University, we take them very seriously and punishments for them may range up to permanent expulsion from the University.
Proper acknowledgment of another's ideas is expected, whether that use is by direct quotation or by paraphrase, however loose. In particular, if any written source is consulted and material is used from that source, directly or indirectly, the source should be identified by author, title, and page number. Any doubts about what constitutes “use” should be addressed to the instructor.
From Joe Williams and Larry McEnerney, “Writing in College,” in Engaging the Humanities at the University of Chicago (Chicago: University of Chicago Press, 1995), pp. 206-207:
When you want to use the exact words you find in a source, stop and think. Then, type a quotation mark before and after, or create a block quotation; record the words exactly as they are in the source (if you change anything use square brackets and ellipses to indicate changes); cite the source.
Those are the first three principles of using the words of others: unambiguously indicate where the words of your source begin and end, get the words right (or indicate changes), and cite the source. Omit the first or last step, and intentionally or not, you plagiarize. You also plagiarize when you use someone else’s ideas and you do not credit that person.
It is trickier to define plagiarism when you summarize and paraphrase. They are not the same, but they blend so seamlessly that you may not even be aware when you are drifting from summary into paraphrase, then across the line into plagiarism. No matter your intention, close paraphrase may count as plagiarism, even when you cite the source.
For example, this next paragraph plagiarizes the last one, because it paraphrases it so closely:
It is harder to describe plagiarism when summary and paraphrase are involved, because while they differ, their boundaries blur, and a writer may not know that she has crossed the boundary from summary to paraphrase and from paraphrase to plagiarism. Regardless of intention, a close paraphrase is plagiarism, even when the source is cited.
