The ability to find, assimilate and produce your own work is becoming increasingly hard for students and the temptation to plagiarise is becoming harder to resist.

Here’s why:

There is a massive shift taking place in education.  When I did a research task as a student in high school, I would go to the library, get a number of books and then lay those books all out in front of me.  As I found information in each of those books, I would need to assimilate that new information into my notes and then rework the assignment to make the text cohesive.

I was limited to the information that was made available in the libraries in my district.  If the information wasn’t in those books, it didn’t exist.

It was easy for us to plagiarise because their wasn’t plagiarism checkers, but at the same time we didn’t have an overabundance of information to choose from.

“Now students have such a vast amount of information available to them, the hard part isn’t finding SOME information, it is finding RELEVANT information.”

An ethics survey in 2010 looking at student cheating found the following:

Rampant cheating in school continues. A majority of students (59 percent) admitted cheating on a test during the last year, with 34 percent doing it more than two times. One in three admitted they used the Internet to plagiarize an assignment.

In Australia, the ACARA ICT General Capabilities require that students be able to recognise ownership over their own work by the end of the first year of school and understand that they shouldn’t copy someones work by the end of year 2.

There are easy ways for your students to cite their sources (see the next post), but how do we quickly check for plagiarism?

Paid Plagiarism Tool:

TurnItIn. Turn it in is one of the most popular plagiarism tools for teachers.  Schools have found the cost to be well worth the benefits that this tool brings to the school.

Turn it in isn’t just a plagiarism tool, there are several other tools that enable teachers to sync documents to their tablet for marking, provide formative feedback to students etc.

  • Is robust and used by tens of thousands of organisations
  • Provides teachers with a percentage of student work that has been plagiarised

  • The Cost (educational pricing is available, but will be expensive if it is just another tool no one uses)

  • Can take longer to mark an assignment if you are also checking positive results
