Snake (in the grass)

A recent posting in an OCC forum* got me investigating again.**  The post included a recommendation for the free “plagiarism scanner” Viper.

I have warned about Viper, and its parent company scanmyessay.com in an earlier post, Authentic authenticity. There I noted that Viper’s then Terms and Conditions included the statement

When you scan a document, you agree that 9 months after completion of your scan, we may upload your essay to our student essays database so that other students may use it to help them write their own essays. You agree that any right you may have to remuneration for such use of documents is waived.

Some of the other sites using that same “student essays database” are paper mills, selling on pre-written student essays. Viper and Scanmyessay may be free to use, but the cost is the possible loss of one’s original essay, one’s rights to it, and the possible loss of one’s reputation.

That wording is slightly different Continue reading

There has been a bit of a splash in the last few days, publicity regarding a study of Turnitin by Susan Schorn of the University of Texas.

iSchoolGuide, for instance, splashed an item by Sara Guaglione: University Of Texas At Austin Writing Coordinator Susan E. Schorn Finds Turnitin Software Misses 39 Percent Of Plagiarized Sources, and EducationDive posts a similar take on the story, this by  Tara García Mathewson, Plagiarism detection software often ineffective.

There is not a lot new here, not for regular readers of this blog. Turnitin is ineffective.

Both articles are based on a post in InsideHigherEd by Carl Straumsheim, What Is Detected? worth reading, for its content and for the comments it has generated. Again, not a lot new, not for regular readers of this blog. Turnitin is ineffective (as are other so-called plagiarism detectors, it is not just Turnitin which is problematic).

Straumsheim goes further (than Guaglione and Mathewson), pointing to Turnitin’s propensity to assign false negatives Continue reading

How much plagiarism? (revisited)

The Bangalore Mirror today publishes a report:  Ctrl-C-Ctrl-V, but only up to 25%, VTU tells its PhD students, with the sub-heading

After installing new anti-plagiarism software to sniff out borrowed material, the technology varsity has realistically left some room for ‘permissible lifting’.”

It seems that students have been turning in their PhD theses with more than 50% “borrowed” material.

A VTU official said the new plagiarism software aims to inculcate in students respect for academic integrity and discipline, even as it identifies acts of dishonesty.

To restore credibility to the University’s degrees, and (as stated in the article) “to inculcate in students respect for academic integrity and discipline, even as it identifies acts of dishonesty,” the amount of allowable plagiarism is to be capped at Continue reading

The online Times of India (30 June 2014) carries an item by Somdatta Basu, IIM cuts out copy-paste, which describes how the Indian Institute of Management, Calcutta (IIM-C) seems successfully to be reducing the number of plagiarised papers submitted for assessment.

The Institute has been using Turnitin for more than a year. In the article, one IIM-C professor is quoted as saying:

“It has had the desired effect. If a professor finds that a work is not an original one, then there are penal provisions in accordance with the institute’s policy on plagiarism.”

“Penal” might not be Continue reading

WriteCheck has introduced a new feature, Ask WriteCheck, in which students are invited to ask questions about “plagiarism, citation, grammar/writing, and many other tricky situations that may occur at school.”

The very first question posed to Ask WriteCheck gets a very strange answer, one of those Continue reading

A frequent question in academic and educational forums is, “How much help can a student get?”

The answer, not surprisingly, must be “It depends.”

In the first place, it depends on the terms of the assignment. If the instructions state that the work must be done without help, then no help is permitted.

If the instructions state that the work can or must be carried out in consultation Continue reading

Carried away

Every so often, we have a good laugh – or cry – at a newspaper report of someone who, believing their GPS rather than their own eyes, drives a high vehicle into a low bridge, or drives into a river,  or maybe drives 3000 km across Europe on what should have been a one-hour journey. No, surely not?

And then there is Turnitin. I often wonder whether Turnitin and its sister companies sometimes get carried away, Continue reading
