What are they trying to prevent? Does eBay think some student is going to fork over the $ to buy the book(s) particular to his/her class(es) - and note, the correct printing/editions of them to match his/her course. Then what, read them (heaven forbid!) or simply memorize the answers?
Or is it more likely kids these days would forgo spending real $ and print media in general and just google what he/she needed to know?
The only slice they are stopping (while frustrating many teachers) is the very small percentage of kids bent on rote memorization. All the teachers have to do to thwart that is mix up the questions, don't ask them in the same order as in the guide/examples. Then, if the kids memorize the questions and answers such that they can handle them any any order... Yikes, they've actually learned something in spite of their best efforts to cheat! Ok, maybe they haven't learn the topic as thoroughly nor as in-depth as you might like but still... With that demographic, I'd take even that as a win.
Really silly, ill-concieved policy IMHO eBay.
This reeks of NEA shenanigans. Follow the money.
***I don't get it. Does eBay really think they are helping keep the answers "secret?"***
I once went to a physical therapist who bragged about his fraternity's filing cabinet full of tests and the answers to them. He was rather stupid and I changed therapists.
Sometime later I worked at a university for a professor who, under the cloak of secrecy, borrowed an exam from another professor and presented it to his class as his own work.
If professors didn't use the same exams over and over again, the students wouldn't be able to cheat so easily.
