WARNING: This plugin replaces Dan Marsden's plugin with a new version developed by Turnitin 

The plugin developed by Dan Marsden has been deprecated for the version now available here.
This plugin shares code with the new mod_turnitintool2 plugin which must be installed at the same time.

The new version has a number of major benefits compared with Dan's including:
  • Fully supported by Turnitin for all issues that occur.
  • Uses a new improved API to connect to Turnitin.
  • Better support for the rest of Turnitin's product range (Grademark, Writecycle etc)
  • Works with the new Moodle block developed by Turnitin

Dan Marsden's original plugin
Dan Marsden's plugin is supported for all versions up to Moodle 2.7 to allow people time to migrate to the new version but will not be supported past Moodle 2.7 - Dan's plugin is still available from his github account here: https://github.com/danmarsden/moodle-plagiarism_turnitin along with documentation here: http://docs.moodle.org/25/en/Plagiarism_Prevention_Turnitin_Settings

    Hi Ryan, if it's a single Moodle environment then you wouldn't be able to have separate configurations. You could configure roles and permissions - as Dan says - if you wanted it only available to certain users but they would still all have to use the same configuration when the other schools came online.

    The documentation link for this plugin still points to the documentation for the Dan Marsden version?

    Using 2.8.1 and Turnitin Plagiarism Plugin (v. 2014012407 2.3+) enabled for forums. Since the 2.8.1 upgrade, it's caused very slow loads in forums of over 30 seconds average. Figured you would want to know the debugging reports (and hope you can offer any advice to get this wonderful plugin working again):

    When I click "Add forum," debugging shows:

    /pluginlib.php has been deprecated, the classes that used to exist are now autoloaded. Please removed any calls to include or require this file.

    Error output, so disabling automatic redirect.

    Since updating to 2014012410 running on Moodle 2.7.2 we are seeing errors in cron:

    Trying to get property of non-object in /moodle/plagiarism/turnitin/lib.php on line 1425

    This was not happening in a previous version we were advised to take from from GitHub by TurnItIn.

    Hi Colin,

    Are you trying to install the whole zip package downloaded from github via Moodle? This won't work due to the way all the aspects of the plugin are packaged together.

    Hi John - Colin is trying to use the install option provided here in the plugins db - it's not working because the plagiarism_turnitin zip here seems to contain an extra "turnitin" directory at the top level instead of the plugin files in the root of the directory.

    Hi Colin/Dan,

    Thanks Dan, the problem was because the zip file was created on a Mac so it contained a __MACOSX folder. I've re-uploaded the plugin so this should now work.

    Mary Evans had brought this to our attention via the Direct plugin.

    Hi,

    What are the chances of this plugin being separated out into logical git repositories or branches? Having it all in the same repository and only a master branch makes it a little tricky to track in different projects.

    Thanks,
    Stacey

    Hi Stacey,

    We're looking at separating the plugins out fairly soon. With our next release we will be splitting the turnitin block out in to it's own repository, if that goes without any problems we will then move on to splitting out the other two repositories.
    Thanks
    John

    Hi guys, please take a look at the issue https://tracker.moodle.org/browse/MDL-49249 , it is reported against Moodle core, what can you recommend to change in plagiarism API to pass a correct link back to the context?

    Hello all, We love the turnitin.com plugin for Moodle, so thanks for the work! I have a question -- I have a second teacher in my Moodle class, and when he corrects assignments via Moodle in turnitin.com, the grades he enters don't appear. His comments do show up. Does anyone else have this issue? Turnitin.com directs me to add him as a TA directly in the turnitin website, but of course as the course is created via Moodle, I can't edit it there. Thanks for your help, Katrina

    Hi Katrina, are they grading via GradeMark or in Moodle? If they are grading in Moodle then the grades will not be passed to Turnitin.

    Hi John, thanks for your response. They are grading in GradeMark. I've done some more troubleshooting on this end and I've realized that in fact, the problem is not exactly as originally described to me. What's going on is that when he tries to use GradeMark under his own account, he is unable to grade the papers. So I think actually we're bumping up against the TA question that I believe has been brought up by others; is it possible to add him as a TA in the Turnitin.com account by having him listed as a teacher in our Moodle Course? Or is this a functionality that still needs to be added? What I'd love would be to have him able to access the Comment Bank that I've spent a lot of time creating in GradeMark, so that we are really grading with consistent comments for the students; but then ideally he would be able to access that comment bank through the link created through Moodle. I am fairly certain this is possible if we were using Turnitin without the Moodle link -- but that's not something I want to give up, as this plugin is so great and I love the pedagogical benefits of one-stop shopping for my students. Is there anything you can do? Thank you!

    He should be able to access GradeMark if he has the Moodle permission to grade the assignment. Which version of the plugin are you using?

    You could also add him as an instructor on the class through Turnitin, this would allow access to GradeMark through the course in Moodle.
