Slop.

I mean, I'm sure that it's pretty much universal that you don't need to be anywhere near as anal about sourcing anywhere outside an academic context. It's still asking a lot of students to expect them to write something to that different standard with no training on how to do so - it was just a different expectation for that one unit. It was tough enough for me as a mature student in my 40s since I had just spent several years having it hammered into my head that every single idea I present must be supported by a reputable source or it's an ethical violation and I can get in trouble. Can't imagine how much tougher it would be for kids straight out of school.
