Great lessons are co-created between students and teachers

I've decided that the three rules for being a great teacher are as follows;
1. Do the right thing
2. Say the right thing
3. Do your best

Isn't that right? If a teacher does and says the right thing and does their best they will be an amazing teacher. Of course, how one knows what the right thing is -- that can be debated forever. The reality is that the right thing changes constantly. It is different depending on the day, the child with whom you are working, the mood you are in that day, etc. The right thing is local, contextual, and impossible to fully plan.
The same goes for doing your best. What is your best? Isn't that also local, contextual, and difficult to really know. We often don't know until after the fact.
So, how do we operate in order to come close to doing your best and the right thing as much as possible. I believe that you must be in the moment with your students as much as possible. Plan, of course. Have the plan, know the content. But, then free yourself to really listen to your students and respond to what they tell you they need. They might tell you verbally, maybe just through their body language, or maybe the message will be in the work that they produce.
I am in the midst of grading papers and have been too busy to write. But, I needed to get at least this much down now. More later.
