An interesting article about teaching in the digital age by Prof.Cathy N. Davidson. It explains why I hate grading :

” Grading, in a curious way, exemplifies our deepest convictions about excellence and authority, and specifically about the right of those with authority to define what constitutes excellence. If we crowdsource grading, we are suggesting that young people without credentials are fit to judge quality and value. Welcome to the Internet, where everyone’s a critic and anyone can express a view about the new iPhone, restaurant, or quarterback. That democratizing of who can pass judgment is digital thinking. As I found out, it is quite unsettling to people stuck in top-down models of formal education and authority.”
