"The Curse of Knowledge"
One concept they bring up is what they term, "The Curse of Knowledge." In short, the curse is this:
Once we know something, we find it hard to imagine what it was like not to know it. Our knowledge has "cursed" us. It becomes difficult for us to share our knowledge with others, because we can't readily re-create our listeners' state of mind.*
It got me to thinking about how this applies to education. When do we - as teachers, administrators, technology directors - make assumptions about what our audience knows? When do we talk over their heads and then blame them for now understanding? The truth is, I think it happens way too much.
When communicating with each other, with parents, and with students we must carefully examine our perspective and assure we are not "cursed" by our own knowledge.
