Showing how accidental copying as well as willful plagiarism can occur, the program lays out the dangers of cheating, then illustrates the pitfalls of non-attribution and patch writing while showing how to properly attribute and paraphrase a lengthy quotation.

There are many instances of plagiarism that are purposeful and clearly a form of cheating. However, failing to carefully cite other people's ideas and language in the body of your writing can also be considered plagiarism. It is important to learn to skillfully give credit to your sources in the body of your writing. These are the three main ways other people's ideas can be incorporated in your writing and given credit with an in-text citation or a footnote.
A brief explanation of quoting, paraphrasing and summarizing with examples
Quoting
When you use someone else's language word for word, you indicate this in a quotation. You must attribute the quote to the original source.
Summarizing
Summarizing is putting the main ideas of a source in your own words. Summarized ideas must also be attributed to the original source.
Paraphrasing
Putting a passage from a source into your own words is paraphrasing. This also must be attributed to the original source.
