How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text. However, this is manually intensive and dependent upon unreliable algorithms.

Others use more sophisticated plagiarism detection software, like Quetext, which can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing.
