Best Practices for Avoiding Plagiarism
- Always Cite Sources: When using someone else's ideas, data, or direct quotes, provide proper citations following your required style guide (APA, MLA, Chicago, etc.).
- Paraphrase Properly: When paraphrasing, substantially rephrase the original text and still cite the source. Changing a few words is not sufficient.
- Use Quotation Marks: For direct quotes, use quotation marks and provide exact page numbers in your citation.
- Develop Original Ideas: Build upon existing research with your own analysis, interpretations, and conclusions.
- Keep Track of Sources: Maintain organized notes and references throughout your research process to avoid accidental plagiarism.
