Yes, Edward committed plagiarism. Even though all of his writing was “original” in terms of the words and sources he used, he committed style plagiarism by following the exact same outline used in his model article. Style plagiarism occurs when you copy the exact same style of reasoning or explanations of someone else, sentence by sentence or paragraph by paragraph. You may verbalize ideas in your own words but the the way the topic is explained is the same as the primary source material.

Plagiarism Means Different Things to Different People

Plagiarism is a rich and inexhaustible topic. It is tricky and can mean different things to different people. There are so many conflicting opinions and so much debate around it.

Thus, we post a few more strips on what we understand under plagiarism.

plagiarism is

We all strive for originality and claim to be different and creative. However, humans are naturally born copycats. In the book I’ll Have What She’s Having, authors show that we, human beings, learn and adapt primarily by observing, replicating and copying others.

We borrow ideas from different time periods and seek for inspiration. We constantly try new things and evaluate what works for us and what doesn’t and thus we imitate others.

However, copying is a driving force of innovation. As Steve Jobs said: “Creativity is just connecting things.” Think how usual things can be enhanced and improved to create something totally new.

As previously noted, imitation is a part of our thinking process.

However, close imitation can be a form of plagiarism. If you imitate or create a parody, don’t forget to always acknowledge the source and the author of the idea. Even if you have just made slight changes or modifications, it’s not fair to take all the credit for the final work. Remember, plagiarism is a bad taste.

As the old saying goes “Don’t reinvent the wheel”. There is no use in duplicating things that have already been created a while ago. Very often, this is a needless and inefficient effort. Simply put, it’s a waste of time.

Another related saying says “Don’t reinvent a square wheel,” meaning you can create something of a bad design or something that isn’t as good as the original.

Why solve a problem that others have solved? Instead, be original and create something unique.

And don’t forget to carry out a plagiarism test on your written work!

Plagiarism Case: Papers Have the Same Core Idea

As you read the case, see if you can tell whether or not it is plagiarism before reading the verdict.

Julie’s idea was to explore the novel The Scarlet Letter with the assumption that Hester’s daughter, Pearl, knew exactly why her mother had to wear the scarlet letter. As Julie wrote her paper, she stumbled upon the same core idea in an authoritative source, used it for her paper but has not mentioned it in the references. Is it plagiarism or not?

You may want to read the article about different types of plagiarism first. Understanding the various kinds of plagiarism and how to avoid them is essential for academic success and, as the old saying goes, practice makes perfect.

Yes, Julie committed plagiarism. She found out that the core idea of her paper was not original or new to her. This can be frustrating when you think you’ve come up with a new idea that hasn’t been written about before. Julie really wanted that idea to be her own, but when she found someone else had the idea first, she should have cited the journal article and mentioned that her conclusions were going to be different from it, especially since the article was from a well-known journal. Whenever you think you have a new idea, you should always carefully research it to find out if anyone else has had that idea as well – chances are good that you’ll need to cite some sources with the same idea.

How to Paraphrase a Passage From a Book: Practical Tips

Practice Paraphrasing

Original sentence (taken from the book “Confessions of an Advertising Man” by David Ogilvy)

Over and over again research has shown that photographs sell more than drawings. They attract more readers. They deliver more appetite appeal. They are better remembered. They pull more coupons. And they sell more merchandise. Photographs represent reality, whereas drawings represent fantasy, which is less believable.

Paraphrase 1:

Being more true-to-life, photos can capture the attention of customers much more easily than drawings, which usually have an artificial feel. That’s why, as D. Ogilvy  stated (“Confessions of an Advertising Man” 2004), photos tend to sell more merchandise and prove to be more appealing than drawings.

Paraphrase 2:

Photos attract more readers. They can be easier to remember because they look more realistic than drawings. This is the main reason photographs can sell more, pull more coupons and bring more appetite appeal.

Which one is correct?

Paraphrase 1 shows acceptable paraphrasing. Since the ideas are rendered with different words and the original source is properly acknowledged. Paraphrase 2 constitutes unacceptable paraphrasing, having failed to give credit to the author of the idea. In the second example, both sentence structure and words used are duplicated, which is a clear sign of plagiarism.

Yes, Matthew committed plagiarism.

What is Plagiarism? A Complex Phenomenon of Copying

What is plagiarism? Plagiarism is a complex phenomenon that is present all over the world in different forms and formats. Some forms of plagiarism are obvious and some are not, but are just as wrong. Some cases of plagiarism may not be considered scientific misconduct, but are unethical in nature.

Today, we post a few more strips on what we understand under plagiarism.


Plagiarism is… Google is often the only source students use while writing academic papers. Obviously, to search for any information, you have to go to Google. But remember, just typing something into the Google search bar, won’t give you reliable results.

If you want to use Google, we highly recommend you using Google’s academic engine Google Scholar that allows to search for scholarly literature and limits the search results to only academic books, journals and websites.


Plagiarism is…  Submitting the wholly stolen paper as your own is the worst case of plagiarism. It can lead to expulsion from the university or legal action. Don’t violate your university plagiarism guidelines and above all be original.

Express your own ideas. Put other’s ideas into your own words and give credit to the author. Never write a paper using just one source. Submit unique papers.


Plagiarism is…  Although, Wikipedia content is given away for free, copying exactly from Wikipedia is still considered plagiarism. If you are using it as a source, make clear that you are quoting Wikipedia, in spite of the fact that Wikipedia’s license allows you to reproduce the information without citing it. If your teacher spots plagiarism, you won’t get a good grade.

And remember, Wikipedia content is created by other users and contains primarily general information. Learn how to effectively use Wikipedia here.

Be aware of plagiarism and take care!
