When I TA'd, I took a hard line on any cheating I detected. Basically it was a 2-strikes approach.
I didn't use turnitin or other mechanisms. I figure, if someone is smart enough to cheat well enough that it's not detectable, it's okay to pass that person. It's not "great", but it's not unleashing a total disaster onto the world.
The cheating I detected was usually because those students were moronic. I am not talking "slightly different". I'm talking, copy-pasted from prior semesters, with 1 modification: the name. Or copy-pasted from the other person in the class with 1 modification.
