Jana Bielecki We use Turnitin integrated with Blackboard Ultra and in the new version there is the option to re-submit 

Claudia Kunschak This has been a Turnitin stipulation for a very long time. Students can actually submit and then re-submit as many times as they like. Within any 24 hour period, the similarity report can only be produced immediately 3 times and the 4th takes another 24 hours. This is a sensible rule and prevents them trying to simply tweak and  repeatedly submit in order to just get their score down. If they submit early enough and follow advice to not submit at the last minute they should not have a problem. The assignment should also be open for submission well in advance of the due date to allow a draft to be submitted and re-submitted. In theory, over a period of one week they could actually submit 21 times and have a report generate immediately. That is my understanding of the rule, but Kat may say differently.

Claudia Kunschak How do your students submit, Claudia? We use the link into Blackboard. When we had Direct 2,5 it initially allowed students to upload as often as they liked, BUT, would only generate 1 similarity report every 24 hours. We used to get students uploading perhaps 2 hours before the deadline, seeing an error, then reuploading, and not being able to do the final check. 

A few years ago, that changed to max of 3 checks in the first 24 hours, and then 1 every 24 hours. That, we felt, gave a balance between allowing the students to update their work, but also stopping the concern that some staff had that students would upload 20 or 30 times with a wee tweak each time to try to get to the (mythical, though many students believed it existed) 'magic' number. 

I still get staff worrying that students will upload multiple times, however, when I look at the actual data, the average upload in most classes is 1.not very much ... so for every serial re-uploader we have 40 or 50 who're happy with the single upload. 

Laura Dean Thank you for the clarification. I did not understand those details and was worried since the 3-times rule seemed to pop up for the first time when you set when students can see the similarity. It makes total sense now and students can still upload with time in-between. I tend to open it 1 week before the due date.

Emma Duke-Williams Thank you for the clarification. I agree, students should not obsess over this and if they wait until the last minute, it is their own decision. I suppose I was confused by the 3 times within 24hrs of the first submission which is actually the max they can upload in a short time but not the total they can upload. I had thought that they needed to upload within the first 24hrs of their first submission. I guess I am more worried than my students....We have turnitin integrated into our Microsoft suite I believe.

Emma Duke-Williams Agreed!! (the mythical magic number!)  Although they have the opportunity to tweak and re-submit if they submit early enough, very few will submit more than once. The single submitters are usually the ones leaving it until last minute and sadly, that is a very large majority.

Laura Dean I thought it was 4th & subsequent take 24 hours, so, in your week (I encourage staff to opne the submission point at the point of coursework distribution, which for our students is generally much more than 1 week). 
However, 1 week would give the students 3 (day 1) + 6 (days 2-7) , so, 9. As you say, few go beyond 1. 

Jana Bielecki 1 submission only is linked to how the instructor set it up - there are 3 choices 

• create similarity now can resubmit
• create similarity now - can't resubmit
• create the similarity at due date.

I can't remember the exact phrase they use, but effectively that's what they all mean. For the last one,   students can reupload if they realise it's the wrong version etc., but no similarity util the due date - so no options to use TII as formative.
