Note: You are currently viewing documentation for Moodle 2.2. Up-to-date documentation for the latest stable version is available here: Plagiarism prevention.
Plagiarism is when a student submits content they have copied and the real author was not given credit for the words. Plagiarism prevention detects when this form of cheating or academic dishonesty has happened.
Moodle doesn't come with any pre-installed plagiarism prevention methods - they need to be added by a site administrator. See Managing plagiarism prevention for details.
