he best way to make sure you don't plagiarize due to confusion or carelessness is to 1) understand what you're doing when you write a paper and 2) follow a method that is systematic and careful as you do your research. In other words, if you have a clear sense of what question you're trying to answer and what knowledge you're building on, and if you keep careful, clear notes along the way, it's much easier to use sources effectively and responsibly and, most of all, to write a successful paper. If you have questions about plagiarism at any point in your research or writing process, ask. It's always better to ask questions than it is to wait for an instructor to respond to work that you have turned in for a grade. Once you have turned in your final work, you will be held responsible for misuse of sources.
