Remember: plagiarism is a deliberate act of academic dishonesty. COD Library strongly believes in the distinction between plagiarism (actively cheating) and novice writing mistakes (such as incomplete or missing citations, patchwriting, etc.).
As you learn how to write as a college student, you will make mistakes!
College, or academic, writing has its own set of rules that are different from other kinds of writing. As with any rules, we learn them by making mistakes. If you have ever learned to drive a car or play a new game, you are familiar with the feeling of not knowing all the rules.
Mistakes, of course, are unintentional - they a natural part of learning. Whether you were taught academic writing in high school or never learned it at all, there are many opportunities for pitfalls and just as many opportunities to learn something new.
How well do you know the rules of college writing?
