Hi,
When Donald uses an idea, quotation, or summary from a source in his research and he does not cite the source, that is called "plagiarism." Plagiarism is the act of presenting someone else's work, ideas, or words as your own without giving them proper credit. It is a form of academic dishonesty and is not acceptable in any scholarly or professional setting.
By not citing the source, Donald is essentially taking credit for someone else's work and misleading his readers into thinking that the ideas or information are his own. This not only violates ethical standards, but it also undermines the integrity of his research.
To avoid plagiarism, it is important for Donald to always give credit to the original source by providing proper citations. This includes acknowledging the author's name, the title of the work, and other relevant information depending on the citation style used. By doing so, he not only demonstrates academic honesty but also respects the intellectual property of others.
It is worth noting that there are different citation styles, such as MLA, APA, and Chicago, which have specific guidelines for citing sources. Donald should consult the appropriate style guide recommended by his instructor or institution to ensure that he follows the correct citation format.
In conclusion, when Donald fails to cite a source when using ideas, quotations, or summaries in his research, it is considered plagiarism. To avoid this, he should always give credit to the original source by properly citing it according to the required citation style.
I hope that this helped you. :)
