Sometimes our understanding of deep learning isn’t all that deep. Typically, it’s defined by what it is not. It’s not memorizing only to forget and it’s not reciting or regurgitating what really isn’t understood and can’t be applied. The essence of deep learning is understanding—true knowing. That’s a good start but it doesn’t do much to help students see the difference between deep and surface learning or to help persuade them that one is preferable to the other.
