The NECC Academic Ethics and Plagiarism Policy defines plagiarism as "the use of any other person's research, images, words or ideas as though they were your own, without giving appropriate credit to the original source." If you are caught plagiarising, disciplinary action may be taken against you.
Why is plagiarism a big deal?
Plagiarism is a form of academic dishonesty, which means you aren't respecting the integrity of someone else's work. When you plagiarize, you are presenting someone else's work as your own without giving them credit for the work they put in. Imagine if you discovered someone was using pieces of your papers without your knowledge.
Academic scholarship is built off of collaborative sharing of ideas. Using someone else's idea to make a point is fine but you must give them credit so people reading your work know who originally came up with the idea. Your credibility as a college student is on the line if you are caught plagiarizing.
