How to prevent plagiarism

What is plagiarism?

First of all, let’s differentiate between a copyright violation from academic plagiarism. The first is the theft of somebody’s intellectual property without giving credit to its owner, and it is punishable by the criminal code. The second is the use of someone else’s words—even if they are not protected by copyright—without the proper indication of a source. The latter is more likely to be within the scope of the ethics code.   We give this explanation, as some people believe if there is no copyright and no author indicated, it is public “common knowledge” that can be used in a paper without reference. That is why at the beginning of each course, it is crucial to explain what academic integrity is, and what academic plagiarism is.   We also recommend each educational institution to have a document explaining the principles of academic writing as clear and simple as possible. This will prevent a huge percent of plagiarism attempts, as students will not have the “I didn’t know it was plagiarism” excuse.

Why is it important to prevent plagiarism?

Plagiarism is fraud and as such, it influences one’s progress in studies and the comprehension of ethics and morality. It can also affect the future reputation of a student, if any cases of plagiarism come out. Even though we have finally taught the younger generation that intellectual property is exactly the same property as material goods, there might still be difficulties with public property. There are people who think that if the appropriation of something does not harm anyone, it is not a violation and hence, it is permissible.   For this category of plagiarists, we need to clarify why society does not accept scientific appropriation: –  Scientific knowledge must progress. If all scientific works were a mere rewriting of knowledge that already exists, with no original content, the stagnation of science would begin. – The thoughtless copying of someone else’s text doesn’t lead to a student’s progress. The copy-paste practise has a negative effect on memory, self-esteem, and can also lead to the disability of a student to create something unique in the future, as creative abilities have a tendency to atrophy if they are not used.

How to prevent plagiarism

We should understand the reasons behind plagiarism.   These are some examples of how a student might think:


Reason: I plagiarised because the source was very well-written. I will never write it better, so why should I even try.

Response: Explain the rules of quotations to such students. It is okay to use good words by others. All you need to do is to cite them properly.


Reason: I plagiarised because my parents will be upset if I get a bad mark.

Reason: I plagiarised because I did not have time. I wanted/needed to do something else.

Response: Talk about priorities. A small explanation of how important it is for you to hear the student’s own opinion will help to cut off the plagiarists who came to it because of the fear of failure.


Reason: I plagiarised because the subject is difficult/not interesting and I will never need it in my life.

Response: Talk about ethics and morality. A student should follow the academic integrity or the honor code of your school or college. In case the topic of the paper is difficult or seems to be not that interesting, make sure to talk to your instructor beforehand. Teachers are able to give a more detailed explanation of the subject and its importance in education.


It is always better to prevent something than dealing with bad consequences after. To prevent plagiarism, you can

  • offer new types of work and topics for students. It is difficult to write something new or original on a topic with thousands of papers already written on it.
  • ask to analyze, not to describe, and give more specific subjects—not common ones, so that for creative writing it would be impossible to copy-paste, as there would be no book to copy from.
  • choose interpretative and inquisitive types of work.
  • suggest a topic that can evolve and be worked on for several years

What is considered plagiarism?

The honor code divides several types of dishonesty and plagiarism:

1.Plagiarism of text, aka borrowing without attribution

This is the most common kind of plagiarism that is not acceptable in any kind of educational institution, as it is a direct theft of someone else’s text. In word-to-word plagiarism, plagiarism-detection software will show 75%-100% of the non-original text.

Original:

“Shakespeare’s plays are divided into five acts. The acts are then divided into scenes. Read a comedy and a tragedy, such as “As You Like It” and “Macbeth,” paying special attention to the structure of the play and what Shakespeare tries to accomplish in each of the big parts.” – Roy Peter Clark, “50 Writing Tools”.

Incorrect:

Shakespeare’s plays are divided into five acts, which are then divided into scenes. Read any comedy and any tragedy, like “As You Like It” and “Macbeth,” taking notice of the structure of the text and what Shakespeare tried to cover in each part.

Correct:

“Shakespeare’s plays are divided into five acts. The acts are then divided into scenes. Read a comedy and a tragedy, such as “As You Like It” and “Macbeth,” paying special attention to the structure of the play and what Shakespeare tries to accomplish in each of the big parts” (Clark).

Text is taken into quotation marks, as it is a word-to-word quote, and an in-text citation is included. Word-to-word quotation is mainly used when ideas are so well written, that there is no sense in paraphrasing them.

2.Patchwriting, aka paraphrasing

This is stitching paraphrased parts from different sources into one paper. This demands some skills from a student, as well as an understanding of the text. Depending on the level of paraphrasing, the detection programs will show from 50% to 0% plagiarism. When you will explain the difference between good and bad paraphrasing to your students, you can give this example:

Original:

“Shakespeare’s plays are divided into five acts. The acts are then divided into scenes. Read a comedy and a tragedy, such as “As You Like It” and “Macbeth,” paying special attention to the structure of the play and what Shakespeare tries to accomplish in each of the big parts.” – Roy Peter Clark, “50 Writing Tools”.

Incorrect:

The plays are usually divided into acts and scenes. Shakespeare’s plays are divided into five acts, and then into scenes. For this exercise, choose a comedy and a tragedy, such as “Much Ado About Nothing” and “Romeo and Juliet”, taking into consideration the structure of the play. Think of the message the author tries to cover in each of the big parts.

Correct:

According to Clark, Shakespeare’s plays are divided into acts and scenes. There are five acts, and then each act has several scenes. For this exercise, choose a comedy and a tragedy, such as “Much Ado About Nothing” and “Romeo and Juliet”, taking into consideration the structure of the play. Think of the message the author tries to cover in each of the big parts (Clark).

Paraphrasing still requires a citation, since the meaning and structure of the text is borrowed from another source. Paraphrased text is put into your own words and due credit is given to the author.

3.Self-plagiarism

This means the student uses his or her own good ideas again and again, without creating new scientific knowledge or any kind of original content. Though it is great that a student has created something worthy once, if he or she uses old works as new ones, that is also plagiarism.

4.Collusion, aka contract help

This means help obtained from a writer, and the copying of a text with the consent of the initial composer of a paper. This is something we cannot easily detect as well. If you have doubts about somebody’s honesty, ask questions. For example, ask to describe the book used, to retell the text of the work in the student’s own words, to tell how the work was written and with what difficulties the student met while writing it.

Remind your students that even the slightest hint of plagiarism can affect one’s academic reputation a lot. One of the brightest examples of scientific plagiarism of the last decade is the Jane Goodall case. In 2013, she was accused of plagiarism in her book “Seeds of Hope”. The book was edited before publication to exclude all inappropriate borrowings, but with scientists of that level, accusations of academic misconduct can not be forgotten (even if you are a lovely animal-lover and the prototype of Jane from “Tarzan”).

How to detect plagiarism?

How to detect plagiarism
  • Manually

  • Search for several suspicious phrases from a student’s paper, and if they were put into a text without paraphrasing, it is quite possible you will detect the source among the ten first links. This method of detecting plagiarism is free, but it is time-consuming, doesn’t detect paraphrasing, and does not detect plagiarism in some of the cases, as it depends on the experience of teachers and professors. To ease the process of manual plagiarism detection, choose statistically improbable word combinations in students’ papers and “google” them.
  • Automatically

How to detect plagiarism with similarity checking tool
  • The benefit of the new generation of similarity detection software is that it provides an advanced search for:
    • word-to-word matches
    • word rearrangements
    • word substitutions with synonyms
    • changes in sentence structure
    • changes from passive to active voice and vice versa
Tools to detect plagiarism

A plagiarism report indicates the percentage of the paper’s originality, and shows which parts of the text have already been published in open sources on the internet. It gives direct links to all sources where similarity has been detected.

What to do when plagiarism is detected?

We recommend you consider these options:

  • Talk to students to find out a cause
  • Allow a rewriting of the paper
  • Give a bad mark
  • Talk to the student’s parents
  • If the issue reoccurs, suspension can apply

Please, consider that today plenty of academic papers are of high importance. They affect students’ futures, even their career choice.   We would also recommend you to read Cheating Lessons by James M. Lang. It is a book about the behavior of students and methods to avoid cheating. There are some examples from the past, some behavioral analysis, and simple ways to decrease plagiarism in your classrooms.
