I've just started a postgraduate course after a long time away from study. I'm really really enjoying the course so far but I'm so worried that I might have paraphrased something poorly in an online discussion board and I'm not sure what to do.
We've been told all about plagiarism and the important of using your own words as well as citing sources and I've been careful about this. Normally I have the sources open while I make the post as the content is quite complex and it takes me a while to post each time, and I check back to make sure I've rewritten it properly (which is normally necessary anyway to summarise).
There was one question where I remembered something I'd read some time ago in a well known book, and I enthusiastically wrote that I'd read this in X's book and briefly outlined an example they used. I remembered in the box the example was written over a few paragraphs and I'd only used a sentence so was sure it was my own words, posted and carried on.
Only later I was interested in something else it had made me think of, opened the book on my Kindle and saw I'd used very similar words albeit obviously very condensed. I wouldn't say they were massively unique phrases as such, more technical terminology but described in a certain order, but it must be I'd retained the info in the way the author wrote it. Obviously I've cited that it's her example and where I read it but I'm really worried that I may have paraphrased poorly and inadvertently committed plagiarism.
I'm feeling really stupid as I knew not to fall into this trap, but I can't edit or delete the post now and will need to submit it next month with all the others as a small percentage of assessment is for contributions to discussion.
My friends have said it looks completely different to them, but there's a couple of instances of four or so consecutive words in my sentence that match the paragraph (admittedly one is a scientific term of three words). It doesn't flag with online similarity checkers but I don't know how they compare with turnitin which it will be submitted through (I also hadn't really considered this when happily posting away on the boards, although I'd been careful about referencing etc on principle. I'd thought more about turnitin for actual assignments).
I'm so worried about it I can't concentrate on study now and have arranged childcare etc so that I can this weekend. Should I email the module lead and ask what I should do or leave it? It would be great if I could delete it, or submit the contributions without it (or maybe they'll say it's fine and I'm worrying about nothing).
I'd literally just asked if I can do more modules and my lack of experience is probably a factor against me but I'm so motivated and sure I can do it and now this.
I'm an awful catastrophiser so any practical advice is really welcomed please!
