Does Teaching=Results?

I saw this quote the other day about teachers.  I really liked the quote and the background is pretty too.  One of the things that I think education suffers from is a lack of understanding that our jobs are hard too.  Politicians try to put it in a box, or make it so that we have to meet certain standards.  What they don't get is that lawyers, doctors, and dentists can fit into that results box because they tailor their results getting to the individual case.  They have a main objective--save the life, win the case, etc...yes there are a variety of ways to get there.  And doctors and lawyers will agree on some of the best practices to get there and others will disagree with those practices saying that another kind works better.  But the patient/client/world doesn't really care as long as the cancer is cured or the bad guy goes to jail.  In the teaching world, our results are not that simple to see.  We all agree on best practices and we all disagree on best practices.  But the trick is knowing that the student learned and that the teacher did their job.  We don't know that as instantly and we don't know that for sure---mostly because like the quote points out--everyone learns differently.  That's why people try to put testing on our students and there is so much pressure to standardized everything everyone learns.  I wonder what it would have been like to teach in the days of the one-room school house, where everyone was grateful for the education that they did get.  Only people questioned the teacher's behavior methods and treatment of their students then--not whether their kid was learning or not. I don't know, maybe I'm just crazy...but what made our society think that teachers should be so results oriented.
