For students, plagiarism often takes the form of:
Using someone else's text without re-writing the original passage entirely into your own words and giving a reference to the source;
Re-using material from a previous assignment of your own in a new assignment without permission from the teacher;
Handing in a report which includes material from someone else's work without giving sufficient attribution to the originator;
Using material from the internet without giving a reference to the source;
Often plagiarism occur because you have copied and pasted material from other sources into your own document, with the idea that you will re-write it later, but then forget which are your words and which you have copied.
Note that it does not matter whether you missed giving a proper reference accidentally or deliberately; both cases are plagiarism.
Assignments that are handed in should be the "final" version and any content in them must not break rules about plagiarism.
Self-plagiarism occurs when one re-uses one's own published work. When re-using your own work, reference the source as in any other case.;
Avoiding plagiarism is relatively easy: always completely re-write other people's ideas or work with your own words and give a reference.

Linköping University can submit student texts to Urkund, which is a plagiarism-checking tool for teachers. Submitted texts are checked against a very large database of material taken from the internet, published material and student material. A report from Urkund is used by a teacher to judge whether a closer look at a text is necessary.
