It hurts me to have to disagree with you because you invoked the He's a tenured professor statement (I have a general bias against tenured professors) and the rest of your argument was right on. I was spitting at my screen until the last few paragraphs of the blog.

I don't trust a college degree from anywhere to prove anything other than that the student was able to finance his/her purchase, regardless of school. I know this will not be taken well by several folks, but it's not a complete disregarding of higher education (take me on my word or call me an idiot, you'll probably be right).

Cheating is a fact of life. When I was in college, the punishment was expulsion. This rarely happened. It was the old "make the punishment so awful that nobody would want to commit the crime", and it fell flat as soon as human beings were put in the picture.

Those who knew how to get away with it almost always got away with it. And even when caught, the book was rarely thrown at them. This "tenured" professor is trying to find a way to separate cheating from passing. I don't know that he'll be successful. But the traditional "Turnitin" approach is working as well as anti-malware software/devices work. It's an arms race. The solution isn't to build better detection or encourage better behavior from users ... it's to make the attack irrelevant.

I'm skeptical that it can be done, but I like the approach. I don't believe this is a Lazy Coward operation (good to edit it out, but I didn't downmod you, I thought your comments were fair). It's a creative, and possibly disruptive, method to teaching.

Edit: Sorry, it's really difficult to write out a reasonable reply without reading it over a few times and making changes.
