In regards to Ray's comment last week, I realized I worded the answer wrong and I appologize. I meant to say that it is impossible for teachers to become complete experts on their content knowledge. We must be competent and have a knowledgeable understanding of our area, but it is impossible to understand and be experts in every single aspect of our content. And, with my area, it would not be ideal to be an expert in every single area of reading. With all of the foundational theories, everyone's reading techniques (at least the ones marketed), and current studies, we would never become an expert in our content because it is constantly changing. It might be more impossible. So, that is why I said we should know our students but I also think we must have an understanding and be good at our content. Experts might be a far cry because we would be reading research constantly and never obtain expertise because it is always changing. We might try, but I believe for these reasons it would be difficult. But, look at historians. They must specify an area to study to become an expert. But, to me, reading encompasses an extraordinary amount of material (we even use it across the content areas it's so vast) so would it be possible to become experts at reading? Or, maybe just experts in one aspect of reading?
